Nobody ever told installer that setting up the Outdoor Temperature Sensor for Heat Pump Temperature Lockouts would be easy! But when we're done The Progression will control/monitor humidification, dehumidification, fresh air ventilation, air filter, and UV Lamp if you desire all of these features. Welcome to the Big Leagues!!

Here we are installing the fossil fuel backup. Between the balance point temperature and auxiliary heat lockout temperature the compressor will operate. However, the fossil fuel will turn on if the room temperature droops approximately 2°F below the temperature setting, and compressor will be disabled.

Also expect to see our friendly electrician bringing you up to modern code, and a technician who paid attention in school choosing appropriate Balance Point Temperature for your home and climate. We must lock out the more costly auxiliary fossil fuel whenever temperature > balance point!
