TROUBLESHOOTING

5.6
Resetting The Thermostat
This thermostat includes an automatic compressor protection feature to avoid potential
damage to the cooling system from short cycling. This thermostat automatically provides a
5-minute delay after turning off the cooling system output to protect the compressor. This
protection is also present in the heat mode of operation on single stage heat pump systems
to protect the compressor.
Low Temperature "Freeze" Protection
While the thermostat is in the HEAT mode of operation on standard heating (non-heat pump)
applications, the thermostat will mechanically initiate a call for heat if the room temperature
drops to less than 41˚F (5˚ C). The system selector switch must be in the HEAT position for
this feature to be active. This feature will allow the thermostat to initiate a call for heat on
standard heating (non-heat pump) applications, to provide a minimum amount of heat, even
if the batteries are dead or missing. Call a Professional service technician immediately to
verify proper system operation. This feature is only active on standard heating (non-heat
pump) applications and is not available on single stage heat pump applications.

Low Battery Detection and Replacement
This thermostat requires two (2) properly installed "AA" alkaline batteries to provide power
for the thermostat to properly control the system operation. The system must have 24 Volt AC
power present for proper system operation and control.
This thermostat is equipped with a low battery detection feature that constantly monitors the
batteries during normal operating mode to
determine whether they have sufficient power
to provide proper operation.
When this feature determines that the battery
status is low, a low battery indicator will appear
in the display. It is recommended that the
batteries be replaced immediately to maintain
system operation and program settings.
Replacing the Batteries
1. Open front thermostat door and locate the battery compartment door.
2. Gently remove the two "AA" alkaline batteries located in the battery compartment.
3. Install two new "AA" alkaline batteries into battery compartment. Make sure to match
the positive (+) ends of the batteries with the positive (+) terminals located in the
battery compartment.
4. Close battery compartment and verify that the low battery indicator does not appear in
the display.
The Reset feature allows the user to completely reset the thermostat to register new manual
switch settings and return to factory set software settings.
1. To erase all entered settings, gently press RESET button using a paper clip or a small
pencil tip.
2. This will return all thermostat settings to their default values and register all new manual
switch settings for proper operation.
SYMPTOM POTENTIAL SOLUTION
Thermostat turns
heating or cooling
system on too often
or not often enough.
Increase or decrease temperature differential setting as
appropriate to provide the desired performance level. See
Setting Temperature Differential section of this manual.
Thermostat does not
turn on heating or
cooling system.
Check to see if OFF is shown in display. This indicates that the
system is turned off at the thermostat. Move the system selector
switch to the HEAT or COOL position. After the compressor short
cycle protection 5-minute period expires the system should start
within a minutes time.
Compressor protection features may be in effect due to
compressor short cycle conditions. See Compressor Protection
Feature section for full explanation of this feature.
Heating or cooling system may be malfunctioning. Call a
professional service technician immediately to verify system
operation.
Check thermostat wiring to make sure that the heating and
cooling stages are connected to the correct terminals on the
wiring terminal block. See Installation and Wiring Diagrams
sections of this manual.
