TROUbLESHOOTING
Symptom
Temperature
display seems
inaccurate.
Problem
Air from the wall cavity may
be leaking into the rear of the
thermostat / sensor enclosure.
The internally fitted temperature
sensor is folded back inside
the thermostat and not being
exposed to the room air
temperature.
External heat or cool source
such as lamps, televisions or
drafts from open doors affecting
the accuracy of sensor.
Sensor calibration setting is
incorrect.
Solution
Plug holes in wall with tape to
prevent leaks.
Carefully move the room
temperature sensor bead so
that it is just behind the sensor
opening in the case.
Move lamps, vents or other
sources of abnormal temperature
away from sensors.
Adjust C1 = XX value in Advanced
Installer Mode to correct
perceived sensor inaccuracy. See
page 26.
