USING A DUCT SENSOR:
The sensor and thermostat are designed to sense air
temperature in a room. The fast moving air in a duct has
small but rapid changes in temperature. This will affect the
control algorithm of the thermostat. For better control, it is
recommended that the air temperature is sensed in the room.
1. Install the indoor sensor using the Single Sensor Ins-
tructions.
2. Clip the thermistor from the indoor sensor with wire
cutters as shown in figure 64.
3. Install the duct sensor in the return air duct according
to the instructions supplied with it. Connect the two wires
from the duct sensor to terminals 1 and 2 of the indoor
sensor. If shielded cable was required because of a
long distance to the sensor box, connect the shield to
terminal 2 also.
TROUBLESHOOTING
Thermostat has no display :
Check wiring between thermostat and sensor.
Incorrect wiring can damage the thermostat, transformer or
blow a fuse.
Check 24VAC supply.
Thermostat reads «AC» :
24VAC power is disconnected.
Not sure if display is showing local or remote
temperature :
Breathe on the wall near the bottom left corner of thermostat.
Temperature will go up for a few seconds if sensing locally.
Thermostat displays very high temperature :
Wires on sensor element are shorted together. Separate
them.
Thermostat displays very low temperature:
Check wiring of probe or duct sensor.
Sensor element is not connected to board or is broken.
