THERMOSTAT AND THERMIDISTAT CONTROL APPLICATION
NON-PROGRAMMABLE ELECTRONIC THERMOSTAT USAGE
* 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 ELECTRONIC THERMOSTAT USAGE
* Model HP thermostat must be field converted to AC operation.
† For use with special 3-stage electric heat setup.
‡ Dual Fuel operation controlled by heat pump when using Model 2S thermostat.
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).
