I have a Taco model 572 valve connected to an existing wired Honeywell TH8110 thermostat for my oil fueled radiator system. I'm getting a new Honeywell TH6320 wireless thermostat for a new A/C installation and I would like to know if there is equipment available that would allow me to connect the wireless thermostat to the Taco valve. The Taco valve is currently connected to a Honeywell control board.
This turned out to be much easier than I expected. The EIM that had been setup for A/C only had the
R Rc Rh terminals connected by jumpers.
- I removed the jumper on the
Rhterminal because the heating system had it's own 24V power.
- I replaced the wire that was coming from the old wired thermostat with a new one that I connected to the
Wterminal on the EIM.
The thermostat had already been connected to the EIM so these steps were all it took.
