I was wondering if you could help explain in detail how my residential heating and cooling system supplies heating & air conditioning. I have a Lennox XP15 heat pump, CBX32M blower coil, EvenHeater Supplemental Heater & a Honeywell Vision 8000 thermostat.
I'm confused about the heating stages mostly. If I set the thermostat to 70 & the indoor temperature is 69, the thermostat calls for heat. The heat pump is first stage, I believe, but I'm confused about the EvenHeater Supplemental Heater 'Temperature Selection Jumper' settings (85, 100, 115 or 130 degrees) and what part they play in the first stage heating, if any, and the second stage heating. I had the 'Jumper' on 130 degrees and my electric bill was enormous so I backed it down to 85 degrees, but the forced air seems too cool so I recently moved the 'Jumper' to the 100 degrees setting. Where should the 'Jumper' be set? When does the EvenHeater activate? How does the EvenHeater work? What does the 'Temperature Selection Jumper' setting mean?
My system was installed by a local, professional company. I just am a little confused about how it all works together.
Thanks for your time.
