GT 351: controlling furnace from rear thermostat
Anyone care to offer a theory of why our rear thermostat doesn't kick on the furnace? The front thermostat works fine but for some reason the back one isn't controlling the furnace.
It's not a huge deal, as the front one works fine, just curious why it won't work the same as front.
With front thermostat off, rear thermostat set to "auto", "furnace" and a high enough temp to call for heat...nothing.
