Or am I missing something? N.O. The Grundfos relay will run your new zone 1. Circulator Pump Relay. Only the Heat Timer 926577-00 will also work with zone valves - Taco and Azel Pump Controllers only work with pumps. Figuring Pump Head. How you wire it up is up to you it just has to be connect this way.Screw the W/R radiant relay to the boiler cabinet or whatever.This will work and save you a ton of money, too. Get your circulator controls from Grainger. I have, I think, already explained this. and your answer is Yes then--. Each Zone Control Panel can operate 2 circulator pumps at the same time. Add up the VA of all the current users when everything is operating and it should be less VA than the rating of the transformer. A timer and temperature aquastat combination is designed to cycle the circulator during peak demand periods. If you were to use the isolation relay then the zone 1 valve would control the Grundfos relay box and therefore the radiant pump. Read below. This system too is usually found on hot water baseboard heating systems. This should be located near the boiler in the near boiler piping. Taco, Azel and Heat Timer pump relays used for many types of hydronic heating systems when you want to control on and off function of pumps. One load must be line voltage; the other may be either line or low voltage. If not, you would need to connect up an auxiliary transformer in parallel with the aquastat transformer. I think I got it. You have 2 zones that are controlled by 2 Honeywell T87F thermostats + a radiant zone run by a circulator controlled by the thermostat on zone 1. What is it about my solution that you don't understand? But I think circulators is a better design. Hmmmm...... what happened to “I am open to any criticism of my solution”? Once the thermostat is satisfied the thermostat contacts open and the motor closes the zone valve. Pumps can be equipped with an internal flow check valve (IFC). When 24v is applied to the zone 1 zone valve motor. Thanks, HomerjSmith! The rugged 3-speed circulatory is specifically designed to provide dial-in precision to meet the requirements of any hydronic heating system, including I was going to control the zones with zone valves and someone asked why I am not using circulator pumps. AN IMPORTANT NOTE: Both the aquastat and auxiliary transformer connected in parallel must be in phase. I thought zones valves were less expensive and quieter and didn't need a flo control valve. REKBDR--No, no, no--That is not correct. TACO Zone Control Product Information Switching Relays Product No. The parallel wiring between zone 1 and zone 2 doesn't mean that zone 2 will control the radiant pump. I just installed a new radiant floor with its own circulator. Connect the radiant pump to Relay 1 on the Grundfos box as previously posted and connect the power to the Grundfos box as previously posted. If you want to get involved, click one of these buttons! Ok, Here's the deal. Then the L1 power supplied to the NO point (now closed) goes to the radiant pump and a white (N) wire goes from the radiant pump to the N wire on the 120V input. You may wish to also turn off the breaker for safety. I need the radiant relay to keep the pump going, even though the Zone valve motor has paused while awaiting that signal. • Zone 1 may be selected to give priority to the indirect hot water tank. But, the latest way to connect everything, thanks to the insight of Iman, is to not use a isolation relay and allow the Grundfos box to control the zone 1 valve. The real concern is the current draw on the aquastat transformer, it is probably 40 VA as that seems to be the standard. The Grundfos advanced, variable-speed, "smart" pumps for hydronic heating systems can reduce pumping energy use by 80%. 4 out of 5 stars (1) Total Ratings 1, $299.50 New. You do need the relay if you want the zone 1 circ to run only with zone 1. SKU: 98996435. If I follow you correctly, the new N. O. relay would be closed (and T-T connected) only when the Zone 1 motor is running. Brand: Grundfos (1)-+ $247.99 each ADD TO CART. We're getting close, but we may not be all the way to where I'd like to be. Each Priority Zoning Circulator has low and high voltage terminal strips for ease of electrical hookup as well as a built-in priority switch. REKBDR--Quit already, it's been solved and stop worrying about zone 2. Using his thoughts, it could be wired this way without the W/R isolation relay. There is a way to do this. Click on image to enlarge. Circulator pumps can stop working for several reasons: a … In the meantime, if the suggestion is to wire the new relay (which then triggers the Grundfos relay) to Terminals 1 and 3, It appears to me that the radiant pump would run whenever the Zone 2 valve is open and calling for heat. Yup! This motor opens the valve. Correct? ZONE 1 ZONE 2 ZONE 3 ZONE 4 120 VOLT CIRCULATORS ZC ZR X X END SWITCH ZONE1 ZONE2 ZONE3 ZONE4 POWER INPUT SR 504 ZONE 2 POWER ZONE 1 relay. I want to wire up its relay (Grundfos UPZCP-1) to the controls for an adjacent room which is Zone 1 of a two zone house. Pump Zone Controls in Hydronic and Radiant Heat Applications. They work with 2-, 3- or 4-wire zone valves and their easy-to-follow PC board layout eliminates the problems caused by incorrect wiring and the unfinished look of conventional zone valve installations. In other words, when the thermostat for Zone 1 (Honeywell T87F) is calling for heat, I want the radiant pump to be operating simultaneously. Click Here for more info. Product description Taco Zone Valve Controls simplify the wiring nightmare. Taco 009-vtf5 Variable Speed Solar Control Cartridge Circulator Pump. Also have that 24v energize the coil of a N.O. Then, with the installation cost added the total price can range from £150-£350. You want the radiant circulator to run only when zone 1 is running and not run when zone 2 is running. Which is better: heating control using zone valves or heating control using individual circulators? Sorry about getting fixated on a 2 wire system. But when the valve is fully open, the Zone motor stops running until it gets a “satisfied” signal from the thermostat. If you have this scenario ("Do you have a #6 screw on zone 1 valve and is a wire connected to it? Look, REKBDR, just wire it up the way you were told and if you have a problem and your house burns down you can call Zman or reach me in my office in Romania. sp-83: 3 zone pump / circulator control (switching relay) with priority for hydronic radiant floor heating systems. Thanks, too, to Zman for heading us in the right direction. us$185.00; On the supply side there's also a shutoff valve for each zone. Knowing the heat load (in BTU's) for a given zone, allows to calculate the required circulator pump's flow rate in gallons per minute (GPM). Add Kate, there can be several things wrong that keeps the water from circulating through the water loop. Variable speed pumps are best for zone valve systems with a one system circulator. The 3 wire zone valve is a White/Rodgers Type 1311. The R845A may be directly controlled by any 2-wire series 80 thermostat, such as the T86A Round Thermostat or T852A Electric Clock Thermostat This is because valves require only low-voltage control wiring. Your home heating system is a typical example for the use of a circulator pump. Heating circulator pumps or "zone circulators" are used to force hot water from the heating boiler through radianting devices such as hot water baseboards or … There are aquastat controls, automatic timer kits, and timers. Circulator Pump Operation The HPZC10* Zone Panels are compatible with common circulator pumps and should be wired as shown in the following diagrams. "I would wire the W/R 115V (COIL) terminals to the boiler pump. When Relay 1 closes, power is supplied to the W/R relay coil, closing the NO points on the W/R relay . It will all operate the same as before. If you want the radiant pump to operate the same time as the boiler pump and be controlled by the thermostat on zone 1, which is a Honeywell T87F, then you just wasted $50 on a Grundfos UPZCP-1.This is the way I would wire your radiant pump to work with the boiler pump. Make sure that you have appropriate wiring available to hook up the thermostat. This energizes the hot water loop circulator pump via a relay. The i-Link controller provides intermediate switching to permit up to 2 circulators and a boiler operating control in a multi-zone hydronic heating system. "If you can't explain it simply, you don't understand it well enough". While pumps may cost from $150 to $200, a valve is only $50 to $60. If you want the radiant pump to operate the same time as the boiler pump and be controlled by the thermostat on zone 1, which is a Honeywell T87F, then you just wasted $50 on a Grundfos UPZCP-1. Switching Relay provides DPST switching for hydronic zone controlled heating systems or SPST control of two separate loads. The Honeywell R8888A Hydronic Circulator Zone Panel with Priority Control is the main control which provides relay switching for multizone hot water control systems. Photo: Grundfos USA. This causes the water to circulate to the zone where the thermostat is calling for heat. It is really a White/Rodgers Type 1361 valve. us$136.00; add to cart . Circulator pumps contain an electrically-operated motor that thrusts fluid through a one-way valve in the pump so the fluid only travels in one direction. The only difference is that the thermostat operates the Grundfos box instead of the zone 1 valve. Switching Relays control the functioning of circulator Pumps. Since this left the kitchen without any place for a radiator, none was reinstalled. The i-Link series 2 zone hydronic radiant floor heating circulator pump controller is operated by low voltage thermostats or any other low voltage controllers having an SPST switching action. OK, this is how I'd do it. A circulating pump itself will typically cost between £90-£160. Boiler Circulation Problems | Troubleshooting Hydronic Water Loops. Taco Circulator Relay - SR503-4 • 3 zones single throw with end switch for boiler • 110 Volts • for Circulating Pumps TACO50130001 • View Detail • Free Shipping Eligible. The boiler operating controlÕs ZC terminal will see the load of the circulator(s). "If I keep in place the existing line from the thermostat directly to Terminal 6, am I facing a problem...?". The panel controls the boiler burner operation and circulator pump motor control for up to three zones in residential or … Pump Zone Controls in Hydronic and Radiant Heat Applications. So two questions: Zone valves vs circulator pumps? I was thinking about Zman's post and solution and he probably has something there. If only 1 zone is open, the entire system is still operating as if it is a single circuit. Rather than stress (with two pumps) the Aquastat relay that controls the boiler pump, I would add another relay.A 115v coil single pole, NO relay (90-291Q White Rodgers) $8.00.I would wire the W/R 115V terminals to the boiler pump, either at the aquastat or in the boiler pump wire housing and then connect the 115V black & white wire that turns on the boiler pump to the NO terminals on the relay that goes to the radiant pump.That is: the added radiant W/R relay coil is wired to the NO terminal on Relay 1 and to the N wire on the 120V input. $150.00 $150.00 Qty . If you were to use an isolation W/R relay and connect it to screw 3 & 1. I am happy to say that I think you have done it, HomerjSmith! Drain any excess water out of the system and close isolation valves that are on both sides of the circulator. Look at the switching mechanism on side B open position on zone 1as to why zone 2 would have no effect on the operation of the radiant pump. I learned that, while I had to figure my total flow on the needs of all the circuits that the circulator would serve, I would only have to base the pump head on what the flow would see while traveling through the highest-pressure-drop circuit. They are also ideal in radiant heat systems that use manifold actuators with multiple zones on a single manifold. But pump head is another matter. The first place to start is the circulator pump. That's what is designed to do and it will work if wired per instructions. The circulator will show its pressure differential as a positive, adding to the overall system pressure and keeping air under control and keeping the system quiet. The only thing is that the gas valve and aquastat circulator relay should if I read the schematic note correctly be connected to screws #3 and #1. Cost of replacing a circulating pump. Might want to check that out. So in the direction the water is flowing, there's a shutoff valve, zone control valve, drain, and another shutoff valve, before the water runs back through the circulator and into the boiler. Zone valve systems are lower in cost as compared to zone pump systems. It looks like you're new here. Years ago a family room (with fin and tube) was added to the house, knocking out the entire back wall of the kitchen. Is this true?") The priority switch allows the installer to choose the zone that requires the most attention and, when activated, run only that circulator. Shop Taco Radiant Heating 3-Speed Circulator Pump in the Hydronic Baseboard Heater Accessories department at Lowe's.com. Free Shipping Policy excludes LTL Truck Deliveries and just a few oversized products. IFC pumps eliminate the need for a separate in-line flow check in the hydronic system. How To Wire a System Circulator to a Zone Valve Control (ZVC) from Taco, Inc. Heat from the family room area was expected to be adequate to satisfy both areas. If so, you then have 3 thermostat wires connected to zone 1 valve, #4, #5, and #6 screws. Are the valves on zones 2 and 3 both opening when either t-stat calls or did someone just use the terminals to tie together the parallel wiring of the end switches and commons? We offer a wide range of universal (compatible with any pump brand) switching relay control modules from Taco, Grundfos, Tekmar and Honeywell in single zone, multi-zone and multi-zone expandable (can be wired together) options. The circulator can run without the burner to prevent short cycling of small capacity zones. The Honeywell T87F sub-base determines whether the thermostat is 2 or 3 wire. Balancing process with valves is harder than zone pumps. I read your post 4 times, boy, am I dense. Thanks guys. Circulator relays on heating boilers - an older and by some heating service technicians, a preferred method to control the distribution of heat to individual building areas uses a individual circulator pump to force heating water through each individual heating zone piping. Weil-McLain 500 Blaine Street Michigan City, Indiana 46360 United States As the valve opens an end switch in the zone valve closes. Here is a crude sketch of the circuits when Z1 is closed and Z2 is open, the green path for the boiler and the yellow for the radiant pump. Hey, Zman, how'd you get a picture of my work? 5. Let me study Zman's comments further. Buy the relay from Supplyhouse.com sku 90-291Q. The Pump End Switch will close a set of dry contacts with every call for heat while the Normally Open 'Zone 1 Pump End Switch' contacts close on a heat demand, wire it to TT on the new switching relay for the Grundfos. Zone 2 operating would have no effect on whether the radiant circulator would run or not. I had assumed zones 2 and 3 were working fine and you are just looking to set up zone one. While developing a plan to improve the performance of the building envelope of this early-1970s, heavily sp-84: 4 zone circulator pump control (switching relay) with selec-priority for hydronic radiant floor heating systems. For the past couple years, I've been helping All Soul's Church in West Brattleboro, Vermont, save energy. If so, my post above will work. The cost to replace a circulating pump will vary depending on the type and brand of pump, where you buy it from, and how easy or difficult it is to install. Turn off water to the circulating pump. ©2000 - 2020 Houseneeds, Inc. • 151 Madriver Canoe Road • Waitsfield, Vermont 05673 • (802) 583-2726, Shipping Delays due to Winter Storm - 2/16/2021. Big Picture—just to help clarify things: the entire house is divided into two zones. For hot water hydronic or radiant heating applications, the following equation can be used: GPM = 0.002*BTU/ (Temperature Drop, F) Circulator Pump Relay. • Zone 2 burner control can be disabled.
