InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers, products, or services discussed at this website. We include wiring diagrams and installation instructions for most zone valve model and multi-zone controllers, and we describe special wiring problems that can occur if you mix different types, brands, or models of heating zone valves on the same hydronic heating hot water heating system.
Above: wiring example for the Taco SR two-zone switching relay. See the SR instructions for important details and safety warnings.
Above: wiring example for the Taco SR three-zone switching relay. To control up to eight heating zones you might wire multiple standard switching relays together as shown in this TACO wiring diagram. Watch out : Be sure to see important instructions and safety notes in that document. The guy who sweated the tubes and zoned it out has never come back to hook up the zone controller.

Absolutely, if properly wired, you can take a single loop of hot water baseboard heat and subdivide it, giving each sub-loop its own thermostat and zone control valve. Properly wired, the individual thermostat calls for heat, the zone valve opens, when the valve is fully open an end switch in the valve connects a second pair of wires that turn on the circulator pump back at the boiler.
On most U. In addition to your control, the Honeywell LCHoneywell's LA,C and A are triple aquastats similar in function, often used to control zone valves. Where you can run into trouble is with an installation that has a mix of different brands of zone valves.
In that case, the wiring instructions for one company may be different from the other. When I got into that trouble years ago I was wiring up a Honeywell zone valve to a system already using Flair zone valves. I called my heating supplier who had Dave Ferris now retired on deck to answer wiring questions. The solution was trivial once Dave said - Just hook the red wire to terminal "x" and the yellow to "y" and so on. My ugly rough sketch above on thi spage needs to be re-drawn neatly, but there I show how we successfully wired-up a mixed brand zone valve installation.
I had two Honeywell zone valves and one White Rogers zone valve. Watch out : in wiring the mixed-brand zone valves shown in my sketch above, it is important that.
The Flair and White Rogers are compatible with one another with no special tricks. I give an example above, but you may need to review wiring with the manufacturers of your zone valves. Zone-A-Trol Valves should not be wired in the same circuit with zone valves of a different make or manufacturer. The thermostat wires on the master primary control will show about volts from the on-board thermostat relay transformer inside the primary control.
No voltage should be presented by the zone valves, thermostat, or transformer circuit TO the primary Controller. We see volts through the zone controllers and transformer but Zero voltage on the zone valve end switch wires that go to the thermostat TT terminals on the master or primary control. Normally one thermostat controls one heating zone and is connected to one zone valve. But as the thermostat is basically an on-off switch, indeed we've discussed with readers the successful combining of more than one zone valve switched by the same thermostat.
Watch out : to avoid overloading the tt or its power or circuit, check the zone valve wiring instructions. For switching multiple zone valves with one thermostat you may need to have the thermostat control a switching relay that in turn switches the gang of multiple zones.

WardWeathers Member Posts: 9. January edited January in Gas Heating. About 5 years ago, a Williamson-Thermoflo GWA boiler was installed for this s vintage square foot house with hot water baseboard. The house is poorly insulated. Prior to conversion to gas, the old oil boiler was able to heat the house. The unit was heating contractor installed. The "new" gas system performs ok when the outside temperatures aren't too bad, i. But when it is sub freezing, as it is now in the Northeast, the heating system cannot keep up, to the point that we've got cold fingers and are dressed for the outdoors, indoors.
The boiler has "functioned" this way on the coldest of days more or less since installation, and I think it has to do with the boiler itself. Original heating contractor's service department failed at figuring the problem out long ago. The boiler setpoint is at deg F. The Economy knob is set to min, because we have trouble keeping heat in the house.
When the outside temperature isn't too cold, the boiler fires up and heats water to deg F, cuts out and lets the circulator pump the hot water until supply temperature drops to deg F, then fires up again.Save Hide Contact Print Share.
