Thermidistat Control
The TSTATBBPRH01-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.

OPERATIONAL INFORMATION
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 simultaneously pressing the F AN 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 temper ature is man ually
changed. It can also be defeated for 1 cycle by simultaneously pressing the FAN button and the 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 3 minutes (2 minutes on Builder’s model).
HEAT/COOL SET POINTS (DESIRED TEMPERATURE)
A minimum difference of 2° is enf orced betw een heating and cooling desired temper atures . This is done by allowing one setting to “push”
the other, to maintain this difference. (Thermidistat Control is adjustable.) Builder’ s thermostats are controlled b y a single set point.
EQUIPMENT ON INDICATORS (NON-PROGRAMMABLE MODELS)
When cooling equipment is ON, a COOL ON icon is displayed above the room temperature display. When heating equipment is ON, a
HEAT ON icon is displayed above the room temperature displa y.
EQUIPMENT ON INDICATORS (THERMIDISTAT CONTROL)
When cooling equipment is ON, a COOL icon preceded by a small triangle is displayed below the cool set point. While cooling equipment turn on is delayed by a staging or cycle timer, the triangle and the word COOL will flash. The same is true for the HEAT icon and
its preceding triangle located under the heat set point. The 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
set point will be on while humidify output is on. The tr iangle under dehumidify set point 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 set point is changed, the 20 minute requirement is deleted. Auto changeover mode can be disabled. Builder’s
thermostats are manual changeover .
EMERGENCY HEAT MODE
When thermostat is controlling as a heat pump and emergency heat is selected, all Y signals are loc k ed out, and W becomes energized
upon a call for heat.
SMART RECOVERY (PROGRAMMABLE MODELS)
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 achiev ed at selected recovery time.
ROOM TEMPERATURE OFFSET (ALL MODELS)
Room temperature may be deliberately offset by up to 5°F in either direction.
MAXIMUM ON/OFF DEADBAND
Maximum sensed temperature difference between ON and OFF is 0.8°F for Builder’s thermostats and 0.6°F for all other models.
