THERMOSTAT AND THERMIDISTAT CONTROL APPLICATION

NON-PROGRAMMABLE ELECTRONIC THERMOSTAT USAGE

			OUTDOOR UNIT
	Air Conditioner				Heat Pump
INDOOR UNIT
	1 Speed	2 Speed		1 Speed		2 Speed
1-Stage Furnace	Model AC or HP*	Model 2S		†		Model 2S‡
2-Stage Furnace	Model AC or HP*	Model 2S		†		Model 2S‡
Typical Fan Coil	Model AC or HP*	Model 2S		Model HP		Model 2S
FK4C Fan Coil	Model AC or HP*	Model 2S		Model HP		Model 2S

*Model HP thermostat must be field converted to air conditioner operation.

†Must use Programmable Dual Fuel Thermostat or Thermidistat Control in this application.

‡ Dual Fuel operation controlled by heat pump when using Model 2S Thermostat.

Non-Programmable Models

The TSTATBHNAC01-A Electronic Thermostat provides single-stage, non-programmable heat/cool temperature control for 24-vac heating-cooling systems with auto changeover. Temperature display can be selected to read °F or °C.

The TSTATBHNHP01-A Electronic Thermostat provides versatile 2-stage heating and single-stage cooling, non-programmable tem- perature control for 24-vac heating-cooling systems with auto changeover. Temperature display can be selected to read °F or °C. Thermostat comes factory set to operate as a heat pump model with second-stage controlling auxiliary electric heat. This model can easily be converted from heat pump operation to air conditioning operation requiring 2 stages of gas or electric heat.

The TSTATBHN2S01-A Electronic Thermostat provides versatile multiple stage, non-programmable heat/cool temperature control for 24-vac heating-cooling systems with auto changeover. Temperature display can be selected to read °F or °C. Thermostat is designed for 2-speed compressor bearing units. Thermostat comes factory set to operate as a heat pump model with 2-stage cooling and 3 stages of heat, third-stage controlling auxiliary electric heat. This model can easily be converted from heat pump operation to air conditioning operation requiring 2 stages of cooling and 2 stages of heating.

Programmable Models

The TSTATBHPAC01-A Electronic Thermostat provides single-stage, 7-day programmable heat/cool temperature control for 24-vac heating-cooling systems with auto changeover. Temperature display can be selected to read °F or °C.

The TSTATBHPHP01-A Electronic Thermostat provides versatile 2-stage heating and single-stage cooling, 7-day programmable temperature control for 24-vac heating-cooling systems with auto changeover. Temperature display can be selected to read °F or °C. Thermostat comes factory set to operate as a heat pump model with second-stage controlling auxiliary electric heat. This model can easily be converted from heat pump operation to air conditioning operation requiring 2 stages of gas or electric heat.

The TSTATBHP2S01-A Electronic Thermostat provides versatile multiple stage, 7-day programmable heat/cool temperature control for 24-vac heating-cooling systems with auto changeover. Temperature display can be selected to read °F or °C. Thermostat is designed primarily for 2-speed compressor bearing units. Thermostat comes factory set to operate as a heat pump model with 2- stage cooling and 3-stages of heat, third-stage controlling auxiliary electric heat. This model can also perform smart-staging with FK4 fan coils (special heaters and setup required) using a single-speed heat pump with 3-stages auxiliary electric heat. In addition, this model can easily be converted from heat pump operation to air conditioning operation requiring 2 stages of cooling and 2 stages of heating (e.g. gas or electric heat).
