Symptom: Cannot program a set point temperature higher than 90˚ F (32˚ C).
Potential Solution: This is above the normal thermostat temperature setting
range of 45˚ to 90˚ F (7˚ to 32˚ C).
Symptom: Cannot program a set point temperature lower than 45˚ F (7˚ C).
Potential Solution: This is below the normal thermostat temperature setting
range of 45˚ to 90˚ F (7˚ to 32˚ C).
Symptom: Fan continues to run all the time whether the system is on or off.
Potential Solution: Check that the fan control switch is in the AUTO position.
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 10.
Symptom: The room is too warm or too cold.
Potential Solution: See section 4 of this manual to verify the current set point
and make any changes that are necessary.
Symptom: System turns on prior to the end of a setback period.
Potential Solution: Thermostat is in Adaptive Recovery Mode. See section 7.
Symptom: NO AUX SET is shown in the thermostat display (2200 and 2200NC only).
Potential Solution: The thermostat (2200 and 2200NC only) is configured for a
conventional system, and the system switch is in the
EM HEAT position. The unit
will still function in a conventional 2 stage HEAT mode, but the display will flash
NO AUX SET. Move the system switch to the HEAT position.

NOTE:
1. Transformer Common not required for battery-only operation
of thermostat. 2. For heating or cooling only system, ignore opposite connection.
3. For 2-wire 24 Volt AC or 250mV - 750mV millivolt heating systems, ignore
cooling connection and fan control.
