fies during cooling.  
AUTOMATIC HUMIDITY  
MENT—When used with the outdoor  
temperature sensor, the Thermidistat  
Control automatically adjusts the humid-  
ity setting reducing excess condensation  
on the windows.  
Bryant’s Thermidistat Control can be used  
to control any equipment application ex-  
cept zoning. It possesses all the features  
and benefits of Bryant’s non-programma-  
ble and programmable thermostats plus:  
ADJUST-  
OVERRIDE CAPABILITY—Hold func-  
tion allows the regular schedule to be  
bypassed with a temporary setting.  
ENHANCED COMFORT—Allows the ho-  
meowner to accurately maintain the  
desired temperature and humidity set-  
tings in the home. By combining the  
functions of a programmable thermostat  
and a humidistat, the Thermidistat Control  
provides temperature control, humidity  
control, and dehumidification.  
BATTERY-FREE—Non-volatile RAM chip  
requires no battery backup. Program is re-  
tained in memory so reprogramming is not  
required after power loss.  
VACATION MODE—With a single touch  
of a button, vacation mode adjusts all  
comfort levels for optimum efficiency  
while the home is unoccupied—or re-  
stores the settings to normal upon return.  
TIMEGUARD—Equipment protection.  
DUAL FUEL MODEL—The dual fuel  
thermostat can be used to control a gas  
furnace and a heat pump. This thermostat  
eliminates the need for an interface con-  
trol kit.  
SMART RECOVERY—Provides consis-  
tent heating and cooling right on time as it  
gradually adjusts indoor temperatures be-  
fore a scheduled change.  
HUMIDITY CONTROL—The Thermidi-  
stat Control accurately controls humidity.  
It humidifies during heating and dehumidi-

Outdoor air temperature sensor is an accessory for all Bryant electronic thermostats, except the non-programmable air conditioner version. It allows the  
temperature at a remote location (outdoors) to be displayed on the thermostat. The outdoor air temperature sensor must be used with the Thermidistat  
Control to automatically adjust humidity setting.  
The outdoor air temperature sensor must be used with the dual fuel thermostat. Do not use with electro-mechanical models.  
Thermostat backplate can be used for programmable and non-programmable electronic thermostats only. This plate is designed to cover surrounding wall  
area located behind thermostat.  
Thermostat conversion kit is a 24-vac accessory that can turn a 4-wire thermostat application into a 5-wire application.This kit can also be used to replace  
a broken thermostat wire, or add an extra wire when needed.

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.

OPERATIONAL INFORMATION FOR ELECTRONIC MODELS  
FIVE-MINUTE COMPRESSOR TIMEGUARD  
This timer prevents the compressor from starting unless it has been off for at least 5 minutes. It can be defeated for 1 cycle by simulta-  
neously pressing the FAN mode button and INCREASE TEMPERATURE (UP) button.  
FIFTEEN-MINUTE CYCLE TIMER  
This timer prevents the start of a heating or cooling cycle until at least 15 minutes after the last start of the same cycle. Its function is to  
assure that equipment is not cycled more than 4 times per hr. This timer is defeated for 1 cycle when the desired temperature is manu-  
ally changed. It can also be defeated for 1 cycle by simultaneously pressing the FAN mode button and INCREASE TEMPERATURE  
button.  
FIFTEEN-MINUTE STAGING TIMER  
In multistage heating or cooling, this timer prevents any higher stage from turning on until preceding stage has been on for 15 minutes.  
This timer is defeated if temperature error is greater than 5°F (usually due to a large change in desired temperature).  
MINIMUM ON TIME  
In normal operation, when a stage turns on, it will not turn off for a minimum of 2 minutes (3 minutes on Thermidistat Control).  
HEAT/COOL SETPOINTS (DESIRED TEMPERATURE)  
A minimum difference of 3° is enforced between heating and cooling desired temperatures. This is done by allowing 1 setting to “push”  
the other, to maintain this difference. (Thermidistat Control 2° and adjustable.)  
EQUIPMENT ON INDICATORS (THERMIDISTAT CONTROL)  
When cooling equipment is ON, a COOL icon preceded by a small triangle is displayed below the cool setpoint. While cooling equip-  
ment turn on is delayed by a staging or cycle timer, the triangle will be flashing. The same is true for the HEAT icon and its preceding  
triangle located under the heat setpoint. These 2 triangles are also used to indicate the state of the humidify and dehumidify outputs.  
See next section.  
HUMIDIFY/DEHUMIDIFY OUTPUT ON INDICATORS (THERMIDISTAT CONTROL)  
Within humidity select screen (selected by Humidity button and indicated by “hu” or “dhu” on clock display), the triangle under humidity  
setpoint will be on while humidify output is on.The triangle under dehumidify setpoint will be on while dehumidify output is active (turned  
off, because this output is reverse logic).  
AUTO CHANGEOVER  
When auto changeover mode is selected, a change from heat to cool (or vice versa) will not occur until an opposite mode demand has  
existed for 20 minutes. If setpoint is changed, the 20 minute requirement is deleted.  
EMERGENCY HEAT MODE  
When thermostat is controlling as a heat pump and emergency heat is selected, all Y signals are locked out, and W becomes energized  
upon a call for heat.  
SMART RECOVERY  
With Smart Recovery selected, transition out of setback begins a fixed time period before selected recovery time and gradually adjusts  
room temperature so that the desired temperature will be achieved at selected recovery time.
