TROUBLESHOOTING
cont.
Symptom:
LO
is shown in the thermostat display where the room temperature is normally displayed.
Potential Solutions:
The temperature sensed by the thermostat is lower than the 40˚ F (5˚ C) lower limit of the
thermostat’s display range. The display will return to normal after the sensed temperature rises within the 40˚ to 99˚ F
(5˚ to 37˚ C) display range. If the temperature in the controlled space seems to be normal, wait for the thermostat to
acclimate to the correct room temperature. If the room seems to be colder than usual, turn on the heating system to
raise the temperature as needed for comfort within the room.
This condition could occur from the system being turned off during a cold weather period or upon installation when
the thermostat has been stored for a long period of time in a cold vehicle or location prior to being installed. The
thermostat should be allowed to warm up prior to installation in order to provide proper heating control once installed.
Symptom:
Fan continues to run all the time whether the system is on or off.
Potential Solution:
Verify that the fan is programmed to run in
AUTO
mode. This will allow the fan to run only
when the heating or cooling system is turned on and running.
Check thermostat wiring to make sure that the fan control wiring is connected to the correct terminals on the
wiring terminal block (see section 6 of the Installer Guide).
Symptom:
Unit will not enter program mode.
Potential Solution:
Non-Programmable mode was selected during Installer Setup (see section 4 of the Installer Guide).
Symptom:
Air conditioning stays on after set point is reached.
Potential Solution:
Dehumidification control is enabled (see section 3.17).
Symptom:
Temporary override of the program set point is limited.
Potential Solution:
Override limit was set in user options (see section 2.4.7).
Symptom:
Heating or cooling set point cannot be raised above a certain limit.
Potential Solution:
Set point limit was set in installer options.
Symptom:
Heating or cooling system turns on ahead of scheduled program times.
Potential Solution:
Adaptive recovery mode was enabled in installer options.
