Error Message
Description
ADJUST ERROR
The control failed to read the Adjust menu settings, and reloaded the factory default settings. Operation
stops until all the Adjust menu settings are checked.
Note:
To clear the error, the access level must be set to Installer and each setting in the Adjust menu
must be checked.
OUTDOOR SENSOR SHORT CIRCUIT
Due to a short circuit, the control failed to read the outdoor sensor. As a result, the control assumes an
outdoor temperature of 32°F (0°C) and continues operation. Locate and repair the problem as described
in the “Test the Sensor Wiring” section.
OUTDOOR SENSOR OPEN CIRCUIT
Due to an open circuit (disconnected or broken wire), the control failed to read the outdoor sensor. As
a result, the control assumes an outdoor temperature of 32°F (0.0°C) and continues operation. Locate
and repair the problem as described in the “Test the Sensor Wiring” section.
MIX SENSOR SHORT CIRCUIT
Due to a short circuit, the control failed to read the Mix supply sensor. As a result, the control operates
the variable speed pump at a fixed output as long as there is a Mix Call. Locate and repair the problem
as described in the “Test the Sensor Wiring” section.
MIX SENSOR OPEN CIRCUIT
Due to an open circuit (disconnected or broken wire), the control failed to read the Mix supply sensor.
The control operates the variable speed pump at a fixed output as long as there is a Mix Call. Locate
and repair the problem as described in the “Test the Sensor Wiring” section.
BOILER SENSOR SHORT CIRCUIT
Due to a short circuit, the control failed to read the boiler sensor. The control no longer controls the
boiler. Instead, the control provides a boiler enable and the boiler operates on its aquastat/limit until the
sensor is repaired. The control will not operate the boiler contact if the Boil Minimum setting is set to Off.
Locate and repair the problem as described in the “Test the Sensor Wiring” section.

HEAT PUMP RETURN SENSOR SHORT CIRCUIT
Due to a short circuit, the control failed to read the heat pump return sensor. The control still operates
the heat pump, but the HP RETURN MAX and HP RETURN MIN settings are no longer used. Locate
and repair the problem as described in the “Test the Sensor Wiring” section.
