Hi,

We have a small boiler set up to control my heat in our Greenhouse Utility room using a Taco controller and Taco pumps now. I am using a simple Honeywell thermostat to monitor and control a zone with radiant heat floors in the Utility room. It is connected to the Taco controller with 2 wires.

We now need a way to monitor and control 2 water reservoirs using the same Taco system that will use radiant pex to heat those reservoirs. We purchased 2 Insteon Wireless Thermostat with water proof temperature probes. We also purchased 1 Insteon Thermostat that will send the on/off signal to the Taco controller. The Wireless thermostat will connect to the non-wireless thermostat via RF remotely.

The standard non-wireless thermostat is a #2441th and the wireless is a #2441zth. The #2441th that will connect to my Taco system has the ability to connect 2 #2441zth wireless thermostats. The #2441th has the ability to control heat 1 and heat 2. Is this for heaters with 2 stages or could this thermostat control 2 separate zones.

I have contacted Insteons customer support but they are saying I need an HVAC tech to help me with the connections. I am hoping that I can use 1 to control 2 zones because they will allow 2 wireless thermostats to connect to it that are in 2 separate places in the home. If not then I may have to purchase 1 more thermostat to be another controller.

Any one that can help it will be appreciated.

Thanks
