Need Wireless Thermostats hooked up to a zone valve controller

Mail4tommo

Hello,

I'm trying to find what set up to use for setting up wireless thermostats (2) to some sort of interface that would hook up to my 2 Taco Zone sentry's. There is no easy way of pulling wire or I would just do that.

I've been looking through the honeywell HZ322 and HZ432 Schematics and I'm a bit confused… The unit is a NTI VM110 and does not have a fan center…

I called Honeywell the support was a bust…

I called Taco tech support for any recommendations and there was no clear answer.

Any suggestions would be extremely helpful, I have been down this rabbit hole on and off the last few days with no avail.

Thanks in advance

Never used these controls and looking at them is giving me a migraine LOL.

I think you could run a lot of wire for what they cost.

The Honeywell instructions are for furnaces air conditioners and heat pumps etc not boiler or zone valves.

You are correct about Honeywell tech support they won't talk to contractors or homeowners only their Honeywell distributors.

I think the control you're looking at is $$$ and has all kinds of stuff you may not need.

Take a look at this control. I don't know if they are any good but less $$$ and straightforward to hook up.

the honeywell is labeled for force air, you need to translate from zone damper to zone valve.

the fan center is t-t or x-x on your boiler, you only need w and r, g and y are for ac.

you could also drive the heat call at the boiler off of the paralleled end switches instead of off of the wireless t-stat receiver/zone controller.

Honeywell/Resideo is making a lot of changes with the RedLink line.

A wireless thermostat was TH5320R1002 with the THM5320R1000 EIM. I don't know if its still offered. A 24 vac transformer should already be there to power the zone valves. I don't know what the va rating is on the interfaces, but I would check first.

Use one of these kits per zone:

Wire 24 volts (available on the control) to "C" and "R", "Rh" and "W" to T-T on the pump or zone valve control.

I don't have any experience with the Braeburn thermostat which communicates using a 433 MHz radio frequency while Honeywell uses a 900 MHz signal. I've used many of the Honeywell ones and they have been very stable, especially in large homes with plaster walls.
