Description
SNOW SENSOR BROWN WIRE OPEN CIRCUIT ERROR
Due to an open circuit, the control is unable to read the brown wire connected to the Snow/Ice Sensor 090 or 094 on terminals 7
and 10. Idling and Storm is disabled and energy saving features such as Warm Weather Shut Down (WWSD) and Cold Weather
Cut Off (CWCO) are operated using the outdoor temperature only.
Check the snow/ice sensor brown and black wires for open circuits according to the sensor installation manual. It may be
necessary to replace the sensor. Once the error has been corrected, the error message automatically clears.
SNOW SENSOR BROWN WIRE SHORT CIRCUIT ERROR
Due to a short circuit, the control is unable to read the brown wire connected to the Snow/Ice Sensor 090 or 094 on terminals 7
and 10. Idling and Storm is disabled and energy saving features such as Warm Weather Shut Down (WWSD) and Cold Weather
Cut Off (CWCO) are operated using the outdoor temperature only.
Check the snow/ice sensor brown and black wires for short circuits according to the sensor installation manual. It may be
necessary to replace the sensor. Once the error has been corrected, the error message automatically clears.
SNOW/ICE SENSOR ERROR
The control is unable to properly detect the Snow/Ice Sensor 090 or 094 on terminals 6, 7, 8, 9 and 10. The control can no longer
automatically detect snow or ice, but manual start of the snow melting system is still available.
Check the snow/ice sensor brown, yellow, red and black wires according to the sensor installation manual. It is important to check
any cable splices for loose wiring connections. It may be necessary to replace the sensor. Once the error has been corrected,
the error message automatically clears.
SNOW SENSOR ERROR
