Question about Heating & Cooling

Open Question

Do you have a wiring diagram for (2) Honeywell V8043E zone valves with separate thermostats?

I'm trying to wire (2) Honewell zone valves to my Weil McLain CG series boiler. The manufacturer's diagrams are confusing. I'm using a 24V transformer and have one circulator pump. My confusion lies around how to tie into the existing boiler circuitry. I found your 2-wire thermostat with a 3-wire zone valve helpful, but my zone valve has 4 wires, and I need to know how to tie it into my boiler.

All of the sudden, my Honeywell zone valve opens all the time even with thermostat lowered.


Have you checked to see if you are getting a power call from the thermostat to the valve? Possible Zone valve stuck open. Pull wire off valve to see if valve closes if not then valve is bad. If valve closes then you need to check to see if you have a wire shorted over from power supplied from stat> If supply wire to valve from stat is making contact with power wire supplied to stat this will keep valve open all the time.

Replacing double pole 220 v with honewell ct410a two wire120/140v wiring diagram not clear


1 power wire (120v) will go to the thermostat and 1 power wire (120v) will go directly to the unit. The other wire on the unit will go to the other side of the thermostat. The safety precaution behind using a single pole to replace a double pole contactor is that you will always have 1 leg of power going to the unit. Many systems are designed like this from the factory, but it is always better to have a 2 pole to cut all power off to the unit unless it's in operation. The unit will still not work as long as it does not have both legs of power.
L1 to Thermostat T1 to Unit
L2 and T2 wired together.

This is only for 240v systems. 120v Will have 1 common and 1 power, therefore you will need to know which wire is which. Power to thermostat, common wired direct.

Replacing WHITE-RODGERS manual thermostat with 3 wires ( red, white, blue and installing Honeywell electronic thermostat RTH110B, how do I connect it? The heating is not central, baseboard heating.


I have only seen one Honeywell thermostat that would work with a 3-wire heating system.

I would replace it with a White-Rodgers 1F80-0471. They are about $100, but they are a good thermostat, and they work well with the 3-wire zone valves.

Most other thermostats have the "Y" terminal that you need, but do not control the zone valve correctly.

I have a red and a white wire but the heater wont


It sounds like you have at least 2 zones in your system. If this is a normal hot water boiler system with zone valves. When you have your thermostat call for heat it closes the 24 volt circuit that then energizes the motorized zone valve for that thermostat. In that motorized zone valve there is an end switch that will close and complete the circuit to the boiler. Zone valves when they start to clog up with mineralization will not allow the motor to go far enough to close the end switch, so then the boiler and circulating pump will not come on. If this is the case then you need to have the zone valve replaced.
Also make sure your wires at the thermostat are connected correctly. One thing you could also check at the thermostat to make sure it works or not is to jumper the 2 wires and see if your system starts up or not. If the system starts up then the thermostat or its subbase is defective. Hope I was of help to you!! Good luck!!

Typically the four thermostat wires are:

R = power (or common)
G= FAN
W = Heat
Y = Cool

Assuming that you have a normal electric or gas furnace and air conditioning, if the heat really is coming on, then just switch the position of the the Yellow and White wires.
