REMOTE SENSOR INSTALLATION INSTRUCTIONS
The T-32-P can use an indoor remote sensor or
multiple sensors for temperature averaging or as
an outdoor sensor for temperature display or a
control function depending upon the thermostat
configuration.
Locate the sensor in the same manner as a
thermostat. Mount the sensor 18” away from any
outside wall. Do not install the sensor behind
doors, in corners or other dead air spaces. Keep
the sensor away from direct air flow, supply
registers or near sources
INDOOR SENSOR INSTALLATION
of heat such as lamps
and appliances. The maximum wire length from the
sensor to the thermostat is 300 feet. Use a
separate 18-2 thermostat cable for sensor wiring.
Prior to wiring the sensor to the thermostat, use an
ohm-meter or multimeter to measure the
resistance of the sensor. Measure at the end of the
wires that will connect to the thermostat.
OUTDOOR SENSOR INSTALLATION
Mount the sensor on a vertical exterior surface
below an overhang. Choose a location protected
from direct sunlight and exposure to excessive
moisture. Follow the same wiring and test
procedures as installing an indoor sensor.

Confirm the resistance value (within 5%) to the
temperature where the sensor is mounted.
Disconnect power to the thermostat when wiring
the sensor to the ‘T’ and ‘T’ terminals. Strip only as
much insulation off of the wires as necessary to
provide a good contact with the terminals. The
sensor is not polarity specific so either sensor lead
may be connected to either terminal on the
BASIC TROUBLE SHOOTING
SYMPTOM
POSSIBLE FAULT AND REMEDY
Thermostat
displays wrong
temperature.
The T-32-P can display in either Fahrenheit
or Celsius. Change CF=C or F in the
Advanced Installer menu.
The fan continues
to run after a
heating or cooling
call is satisfied.
The thermostat is set to Fan ON. Set the
thermostat to Auto Fan. The fan purge
mode is set to run the fan for a fixed period
of time after the equipment shuts off.
Change the FP value in the Advanced
Installer menu.
Some buttons on
the thermostat do
not function.
Lock values have been set. Refer to LC
settings in the Advance Installer menu.
Thermostat clock

proper time.
Make sure that the plastic tab on the
internal fitted battery is removed so that the
battery is operational.

Dashes (---) appear
on the LCD.
Check wiring to outdoor sensor. Make sure
that TT=OA in the Advanced Installer menu.
Heating or Cooling is
flashing while the
HVAC system is
running.
This is not a fault. The T-32-P has a built-in
minimum equipment run time of either 2 or 6
minutes. Sw6 may set for 6 minutes (ON)
which is keeping the equipment on after the
thermostat reaches setpoint. Try setting

higher heating or
lower cooling
temperature.
This is not a fault. HL and CL restrict the
heating and cooling setpoints. The limit
values can be changed in the Advanced
Installer menu.
