Geothermal furnace running excessively on ProTech 520 thermostat

Jan 16, 2015 1 Replies

Do not have owners manual for thermostat so I don't know how to adjust it. I do not fully understand the set point A and set point B feature. Set point A can adjust from .5 to 2 and set point B can adjust from 1 to six. Does this have anything to do with how long the furnace runs?


Can't find any good info on that stat. The .5 to 2 looks like a heat anticipator number. That adjusts the sensitivity of the stat. The 1 to 6 might be the CPH setting. That's cycles per hour.
