We are looking for a thermostat to use with our Elk M1 system for zone control with radiant floor heat. The thermostats we find that have a 2nd temperature sensor to maintain the floor temperature are not communicating and i have not seen that any compatible with the Elk have floor temperature control.
A radiant floor heat thermostat should call for heat like normal except when the floor temperature gets to the max floor temp at which point it should stop calling for radiant heat and either do nothing or start calling for aux heat (via forced air in our case). when calling for cooling it should turn off the floor and call for cooling (comes via forced air again) but not let the floor temperature drop below the minimum setpoint. It should also keep in mind that the gypcrete floors change temperature very slowly.
this is hydronic heat so all the calls are low voltage (i.e., high current, line-voltage version not required)
True, true, this could be done with a standard thermostat and bunch of elk temperature probes along with a couple of rules in the Elk for each zone. however, i have more zones than Elk inputs that can measure temperature and since this is a fairly important task i didn't want it easily messed up. After all, next time my wife may marry for money or looks rather than intelligence and i don't want husband #2 to destroy the house if he can't figure this stuff out.
thanks
