A breaker has turned OFF or a fuse has
blown.
The thermostat set point is incorrect.
In Wall Control.
The master Wall Control timer setting is
incorrect.
Built-in safety timers have been activated
A breaker has turned OFF or a fuse has
blown.
The thermostat set point is incorrect. In
Wall Control.
The master Wall Control timer setting is
incorrect.
The cooling/heating function may not
work effectively if the air inlet and air
outlet on the outdoor unit are blocked.
The airflow across the indoor coil may
not be enough and the anti-freeze
protection or over heat prevention
systems can lower the cycle capacity for
the unit.
The cool/heat load is too great for the air
conditioner.
Open windows or doors will cause
inefficient operation.
Appropriate zones not turned on.
The outside temperature is beyond the
air conditioner design conditions.
You may be trying to operate the whole
house on Auto Fan Mode.
This is caused by the defrosting
operation of the outdoor units heat
exchanger in heating operation in cold
ambient conditions.
Condensation of water on the outdoor
coil during heating operation.
The master control set temperature
limits are reached.

Remedies
Wait for up to 20 minutes to pass from turn on
time.
Check breakers and fuses.
Check master wall control settings are correct.
Check the thermostat "setpoint" is set low
enough for cooling or high enough for heating.
Check the master Wall Control timer settings.
See Operating Instructions section.
Wait for up to 20 minutes to pass from turn on
time.
Check breakers and fuses.
Check master wall control settings are correct.
Check the thermostat "setpoint" is set low
enough for cooling or high enough for heating.
Check the master Wall Control timer settings.
See Operating Instructions section.
Make sure the air inlet and air outlet on the
outdoor unit is not blocked.
Check that the area around the outdoor unit is
free from obstructions that may cause the airflow
to recirculate.
Reduce the total static pressure on the indoor fan
to increase airflow.
For example increase duct sizes, reduce tight
duct work bends or increase return air grille size.
Perform a heat load analysis on the conditioned
space. You may need to consider upgrading your
air conditioner with a larger system.
Close windows and doors in conditioned areas.
Turn on appropriate zones (if applicable)
If you know a extreme day is coming turn the
air conditioner on a few hours before ambient
temperatures reach extreme. This should help on
those few extreme days.
Change fan mode to CONT HIGH fan speed. This
increases the total fan speed. This will boost fan
capacity.
This is normal during the defrost operation in
cold ambient conditions.
This is normal during heating operation. You can
purchase drip trays to contain then drain this
excess water.
Check the upper and lower temperature limits
are set correctly. See operation manual for
details on setting upper and lower temperature
limits.
