Thermostat Fault
The control determines that the
• Low pressure sensor inoperable or not
pressure sensor is not reacting
properly connected
properly.
The control has detected that the
• Outdoor coil thermistor inoperable or not
Outdoor Coil Temperature Sensor is
properly connected
out of range.
The control has detected that the
• Liquid thermistor inoperable or not prop-
Liquid Temperature Sensor is out
erly connected
of range.
• Wiring to control board disconnected
Indicates the control board may
• Faulty control board
need to be replaced.
• Electrical Noise
This error indicates the equipment
• Ambient air conditions too high
is experiencing high temperature
• Stop valve not completely open
faults on the outdoor control board.
This error indicates the equipment
is experiencing high temperature
faults on the outdoor control board.
• Ambient air conditions too high
Control has determined continued
• Stop valve not completely open
operation is acceptable. This indi-
cates they may be a problem with
the equipment.
• Current spike in supply
Board detected a high current con- • Stop valve not completely open
dition. This indicates the potential • The compressor wire is lost phase
for a short circuit. • Faulty control board
• Faulty compressor
• Short circuit condition
• Stop valve not completely open
Board detected a high current
• Overcharge
condition.
• Faulty control board
• Faulty compressor
• Blocked/restricted condenser coil and/
The control encountered an abnor- or lines
mal condition during the startup • The compressor wire is lost phase
procedure. • Inconsistent compressor load
• Faulty control board
Indicates the control board may need • Outdoor fan motor not connected properly
to be replaced. • Faulty control board
• High or low voltage from supply
The control has detected a voltage
• The compressor wire is lost phase
related issue with the compressor.
• Faulty control board
• Thermistors inoperable or improperly
Indicates the control board may need
connected
to be replaced.
• Faulty control board
Control determines that its compres-
• Memory card not correct
sor requirement is different than the
• Control board mismatch
compressor capability.
• Refrigerant leak
The control has detected a low • Low refrigerant charge
refrigerant condition. • Thermistors inoperable or not properly
connected
Control detects a low power supply
• Low line voltage supply
voltage condition.
Control detects a high power supply
• High line voltage supply
voltage condition.
The control detects the outdoor
temperature outside recommended
• Ambient air conditions too high or low
operational range. Unit may continue
to operate normally.
The control is unable to start the
Cooling mode test because indoor
• Heat provided by secondary heating
heat has been turned on by ther-
source
mostat. Please set thermostat to off
position.
Probable Causes
