My first post here and hoping for some help...
I have a gas furnace Lennox whose blower motor died some days ago. I called a guy to replace the motor for me and he put this model on:
Everything looks to work fine, only that the way I control heating/cooling has changed. Before, I could just choose heat (thermostat Robertshaw) http://www.robertshawtstats.com/modu...e&prodID=67345
and the fan together with the heat pump or furnace would start automatically (a second or 2 after setting the temperature). When the room temperature was the same with the one set on the thermostat, fan and heat pump/furnace would stop automatically and starting (both) again automatically when temperature was going down. Now, I have to set the temperature, but nothing would happen till I manually press the fan button. It takes like 3-4 minutes until the heat pump starts heating and the fan keeps going even after the temperature is reached and the heat pump is stopped. I have to go again at the thermostat and stop the fan manually. That's not convenient at all as I do not want to have the fan going and going...Motor is set to high speed and after changing blower filters I get some real noise from one duct entry in my room. I called the guy who replaced the blower motor, but no answer from him...
Do you think it's a wire connection problem here or just a thermostat setting?
Thanks in advance for your help!
