Programmable Dual Fuel Model
The TSTATCCPDF01-A Thermostat provides single-stage or multiple-stage dual fuel operation, 7-day programmable heat/
cool temperature control for 24-vac systems with auto changeover. Temperature display can be selected to read °F or °C. The
Dual Fuel Thermostat is designed with an adjustable balance point for heat pumps when using a gas furnace for backup or
auxiliary heat. Thermostat comes factory set to operate single-speed equipment, but is easily configured to match multiple
stage equipment combinations. This model requires use of the Outdoor Air Temperature Sensor accessory. Using the dual fuel
thermostat eliminates the need for an interface control.

Thermidistat Control
The TSTATCCPRH01-B Thermidistat Control provides single-stage or multiple-stage equipment operation, 7-day
programmable heat/cool temperature control for 24-vac systems with auto changeover. It controls both humidification and
dehumidification and can be used to control heat pumps, air conditioners, or dual fuel applications. Temperature display can
be selected to read °F or °C. The Thermidistat Control is designed primarily as an extension of the programmable thermostat
line to provide humidify and dehumidify outputs in controlling humidity. It can also be field configured to be non-
programmable. Humidify outputs connect directly to 24-v humidifiers. Dehumidify outputs connect directly to variable-speed
furnaces or fan coils that have dehumidification capabilities. To achieve full benefits, this model requires use of the Outdoor
Air Temperature Sensor accessory, which is included with the Thermidistat Control.
The Thermidistat Control comes packaged with the 40FKA for Comfort Heat.
