TT TERMINAL FUNCTIONS
INDOOR SENSOR WIRING
When the T-32-S1 is used as an indoor sensor, the
T-32-P can be configured to allow only the remote
sensor to control the temperature (TT=RS) or both
the remote and onboard sensor can be used for
temperature averaging (TT=AV). An optional in-line
switch can also be used with the remote sensor to
change the temperature sensing location from
remote to onboard sensor. The Advanced Installer
menu setting must be TT=RS to use this feature.

USING MULTIPLE SENSORS FOR
TEMPERATURE AVERAGING
Multiple sensors can be connected to the ‘T’ and
‘T’ terminals if temperature averaging is required
with or without the use of the thermostat onboard
sensor. The total value of remote sensors wired in
series/parallel must equal 10k
@ 77 F.

REMOTE ON/OFF OR OVERRIDE
OFF
Using an external dry contact switch, the T-32-P
can be configured to turn the thermostat off or
change the heating and cooling setpoints to a
pre-programmed override value.
(Figure 9)
To turn the thermostat off, TT=OF in the Advanced
Installer menu. When the switch is closed, the
T-32-P will turn off and the word
will flash on
the LCD. When the switch is opened, the
thermostat will return to the user settings.
For remote override, TT=OC in the Advanced
Installer menu. Override setpoints are programmed
in the Advanced Installer menu using ‘OC’ (Cooling
setpoint) and ‘OH’ (Heating setpoint). When the
switch is closed, the user setpoints are replaced by
the pre-programmed override setpoints. When the
switch is open, the thermostat will return to the user
settings.

TESTING
Testing ensures that the thermostat and the HVAC
equipment operate properly. Follow the detailed
testing steps and refer to the Troubleshooting Guide
in this manual if any problems are encountered.
When the T-32-P is powered, the LCD will briefly
show all available LCD icons, software version, then
display the time and operating mode, etc.

For three sensors, (1) T-32-S2 and (2) T-32-S1
sensors can be wired in series / parallel. For four
sensors, (4) T-32-S1 sensors can be wired in
series / parallel. Both of these configurations can
be used with or without the thermostat onboard
sensor. To include the onboard sensor, TT=AV. To
exclude the onboard sensor, TT=RS.
