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.
