How to Adjust the Running Cycle on My Honeywell Round Thermostat

Honeywell round thermostats are one of the most recognizable items found on the interior walls of a home. The Honeywell thermostats utilize a mercury switch attached to a temperature-sensitive spring to operate the home heating, ventilation and air conditioning system (HVAC). Once set, the furnace or air conditioner cycles will correspond with the thermostat setting until it is changed. You can adjust the cycles of your Honeywell thermostat without special skills or tools.
