Thermostat Operation
A thermostat is an adjustable temperature actuated switch. It automatically turns heating and cooling equipment on and off to maintain constant, controlled temperatures within your home. While thermostats vary with the type of system in your home, the following information applies to most thermostats sold through Central City Air.
System Switch
Positions: "HEAT-OFF-COOL" or "OFF-HEAT-AUTO-COOL". Set the system switch for either heating or cooling. Some thermostats have an "AUTO" setting for automatic heat-cool changeover. This "AUTO" setting may not provide the most economical energy usage, as the system will heat or cool to maintain the temperature chosen, unless your thermostat has two TEMPERATURE SELECTOR settings, one for heating and one for cooling. This gives the best control in the "AUTO" position, since it allows a range between heating and cooling where equipment operation is not needed.
Fan Switch
Positions: "AUTO-ON" or "INT-CONT". The "AUTO" or "INT" setting is for intermittent blower operation, that is, the blower will run only when the thermostat calls for either heating or cooling. The "ON" or "CONT" setting will run the blower continuously, regardless of whether the equipment is heating or cooling.
It is generally more satisfactory to operate the indoor blower continuously, as it provides constant air circulation and filtering, with a more even temperature from floor to ceiling, and room-to-room.
Temperature Selector
Simply set indicator on thermostat to desired temperature. Some thermostats may have two temperature settings, one for heating, and one for cooling.
Programmable Thermostats
With the use of higher efficiency equipment, and increased interest in saving on energy bills, many systems are installed with programmable thermostats. These provide the same SYSTEM and FAN control as standard thermostats, but also provide automatic heating setback and cooling setup. Please refer to the separate instructions provided with your programmable thermostat for operation and adjustments. Lennox and Amana now provide a programmable thermostat for use with two-speed "Power Saver" cooling units.
