Lennox heater won't turn off emergency heat continues to run regardless of thermostat
Thermostat set to 70 yet temp continues to climb (80+). Can't trun off with thermostat switch, must go to air handler and turn CB offand then back on. Then can only get control by placing thermostat to EMER. Then temp responds to what is set in thermostat (both on and off). When going back to HEAT (heat pump) it works OK for a while then again will continue to NOT shutoff as temps go above requested setting. Only turning off CB and then Setting EMER will get heater to respond to thermostat
