Supply Temperature Too High – Check
Sensors
• When:
• During Chill or Frozen Mode: Supply air
temperature is too high compared to return
air temperature under operating conditions.
The state will by time request defrost or/and
probe test.
• Indicates:
• Low refrigerant charge
• Incorrect connection or location of supply or
return air sensor
• Air leakage at supply air sensor cable
• Ice or frost on evaporator coil
• Incorrect evaporator fan operation
• Using DATA menu inspect readings.
• Enter Manual Function Test menu and operate
evaporator fan at high speed to evaluate probe
spread.
24
Supply Temperature Too Low – Check
Evaporator Coil
• When:
• During Chill or Frozen Mode: Supply air
temperature is too low compared to return
air temperature under operating conditions.
The state will by time request extended
defrost, defrost or/and probe test.
• Indicates:
• Incorrect connection or location of supply or
return air sensor.
• Air leakage at supply air sensor cable.
• Incorrect evaporator fan operation.
• Using DATA menu inspect readings.
• Enter Manual Function Test menu and operate
evaporator fan at high speed to evaluate probe
spread.
25
Evaporator Temperature Too High – Check
Evaporator Sensor
• When:
• During Chill or Frozen Mode: Evaporator
coil temperature is too high compared to
return air temperature under operating
conditions.
• Indicates:
• Probe spread, misplaced probes.
• Using DATA menu inspect readings.
• Enter Manual Function Test menu and operate
