Programmable Dual Fuel Model
The TSTATBHPDF01-A Electronic 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 combi- nations. 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 TSTATBHPRH01-A Electronic Thermidistat Control provides single-stage or multiple-stage equipment operation, 7-day program- mable 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. Humidify outputs connect directly to 24-v humidifiers. Dehumidify outputs connect directly to variable-speed furnaces or fan coils that have dehumidification capabilities. This model requires use of the Outdoor Air Tempera- ture Sensor accessory, which is included with the Thermidistat Control.
