Conventional 1H/1C HVAC control

This thermostat provides manual temperature control for single-stage heating and cooling systems. It mounts on a wall and operates at 125VAC with a 24-volt relay contact. The unit features a large backlit display and a built-in level for straight installation. It is sold in a 12-pack case.

Buyers who need scheduling or multi-stage support

The non-programmable design means there are no daily or weekly schedules and no automatic changeover periods. It does not support heat pump auxiliary heat, line voltage baseboard heating or proprietary communicating protocols. Installers requiring those functions should select a different model.

1H/1C single-stage compatibility

The thermostat works with conventional gas, oil or electric systems up to one stage of heating and one stage of cooling. It also supports heat pump systems without auxiliary heat, millivolt and three-wire zone valve applications. Compatibility with your existing wiring determines whether this is the correct part.
