I am disappointed that the W200 does not support variable speed Furnace fans. This is easily accomplished in Software as the thermostat lets the HVAC handle the fan speed.
I have installed 4 of these and ripped them out as 2 of my units are 2 stage cooling and variable speed fans. I was looking forward to using them and the other product but return them and going to Ecobee as there’s has the function and with there sale and power company rebate the Premium unit 260 normally is now 140.
