Two thermostats running one boiler
I've got a unique situation where I am heating an apartment building with apartments having different wind exposure. With a steady wind, one apartment can be 75, and another 68. Averaging temps will not solve this problem. Other than going to an internet based thermostat, and manually switching it as needed, I thought I could run two thermostats. That way, I would be assured of keeping a minimum temperature in different parts of the building.
Is there any issues this might present? If one thermostat is calling for heat, would the control voltage on the back side of the other thermostat present any problems?
Basically, I envision two Honeywell visions, each with one external temp sensor to be installed in an apartment, and then both hooked up to the boiler.
