option 2. The temperature reading of the sensor will be dis-
played. Compare the reading to an accurate thermometer. Use
the left upper or lower set point buttons to raise or lower the
temperature reading (by tenths of a degree) until the desired
calibrated temperature is shown. The range of possible temper-
atures is 30 to 180 F.
Zone Temperature Monitoring —
tem thermostat uses sensors to monitor the temperature in the
zone.
The TEMP system thermostat can do one of the following:
• use the local zone temperature sensor for temperature
information
• use its remote room sensor(s) (field installed) for tempera-
ture information
• average the temperatures it receives from its local room tem-
perature sensor and remote room sensor for temperature
information.
To configure the room sensor, set category 5, option 1.
When the Room Sensor option is set to 1, the TEMP system
thermostat will use the local zone temperature sensor for tem-
perature information. When the Room Sensor option is set to 2,
the TEMP system thermostat uses its remote room sensor(s)
(field installed) for temperature information. When the Room
Sensor option is set to 3, the TEMP system thermostat averages
the temperatures it receives from its local room temperature
sensor and remote room sensor for temperature information.
Remote Room Temperature Sensor —
system thermostat can measure zone temperature through a
solid-state temperature sensor located at a remote location up
to 1000 ft from the TEMP system thermostat. The sensor mea-
sures temperature with a range of 30 to 180 F with
resolution. The remote room temperature sensor is connected
to the TEMP system thermostat through the wiring connector
board. See Fig. 10. Up to 4 remote room sensors can be used.
When more than 1 remote room sensor is used, the tempera-
tures are averaged.
All sensors must be wired in parallel. When adding remote
room sensors, a field-supplied 9.2 K ohm resistor must be add-
ed to the connector block for each sensor. See Fig. 10.
REMOTE ROOM TEMPERATURE SENSOR CALIBRA-
TION — To calibrate the remote room temperature sensor,
configure category 5, option 3. The temperature reading of the
sensor will be displayed. Compare the reading to an accurate
thermometer. Use the left upper or lower set point buttons to
raise or lower the temperature reading (by tenths of a degree)
until the desired calibrated temperature is shown. The range of
possible temperatures is 30 to 180 F.
SET-BACK OVERRIDE — Whenever the set-back override
(SBO) contacts are closed the TEMP thermostat will proceed
in Occupied mode. When the SBO contacts open the TEMP
thermostat will continue to follow the local occupancy sched-
ule it is programmed to follow. The SBO dry contacts are field-
supplied. See Fig. 10.
NOTE: The set-back override (SBO) contacts will only over-
ride the TEMP thermostat's local occupancy schedule and will
not interrupt any devices following a global schedule unless
the thermostat is the Global Schedule Broadcaster.
Duct Temperature Sensor —
thermostat measures supply-air temperature through a solid-
state temperature sensor. The sensor can be located up to
1000 ft from the TEMP system thermostat in the supply air
duct. The sensor measures temperature with a range of 30 to
1
180 F with / -degree resolution. See Fig. 3 for sensor wiring.

The TEMP system thermostat must be configured to use the

duct temperature sensor.

To configure the Duct Temperature Sensor option, config-
ure category 5, option 4. Set the option to ON if using a duct

NOTES:
1. Four (4) is the maximum number of Remote Room Sensors
considered as standard.
2. For each additional sensor (2 or more total) a resistor must be
added. Resistors are wired in parallel between terminals RS–
and W on the thermostat terminal block.
3. Example shown is for 4 Remote Room Sensors.
4. The SBO contacts, when closed, cause the thermostat to oper-
ate in the Occupied mode. When the SBO contacts open, the
thermostat returns to the internal schedule.

temperature sensor. Set the option to OFF, if not using a duct
temperature sensor. The default is OFF.
DUCT TEMPERATURE SENSOR CALIBRATION — To
calibrate the duct (supply air) temperature sensor, configure
category 5, option 5. The temperature reading of the sensor
will be displayed. Use an accurate thermometer to compare
temperature readings. Use the left upper or lower set point but-
tons to raise or lower the temperature reading (by tenths of a
degree) until the desired calibrated temperature is shown. The
range of possible temperatures is 30 to 180 F.
DX (Direct Expansion) Coil Temperature Sen-
sor —
The TEMP system thermostat measures DX coil tem-
perature through a solid-state temperature sensor. The sensor
can be located up to 1000 ft from the single zone relay pack.
