Error Messages

ROOM
The control is no longer able to read the indoor sensor due to an open circuit. The control will continue to operate as
if there was nothing connected to the indoor sensor input. Locate and repair the problem as described in 10K Sensors
L630070. If the indoor sensor is deliberately removed, the control must be powered down, and then powered back
up. To clear the error message from the control after the sensor has been repaired, press the Item button.
VIEW
BOIL
The control is no longer able to read the boiler sensor due to an open circuit. If the BOIL MIN adjustment is higher than
100°F (38°C), the control closes the Boiler contact when the mixing valve starts to operate. The boiler temperature is
then limited by the operating aquastat. If the BOIL MIN adjustment is lower than 100°F (38°C), the control does not
operate the Boiler contact. Locate and repair the problem as described in 10K Sensors L630070. If the boiler sensor
is deliberately removed, the control must be powered down, and then powered back up. To clear the error message
from the control after the sensor has been repaired, press the Item button.

BOIL
The control is no longer able to read the boiler sensor due to a short circuit. If the BOIL MIN adjustment is higher than
100°F (38°C), the control closes the Boiler contact when the mixing valve starts to operate. The boiler temperature is
then limited by the operating aquastat. If the BOIL MIN adjustment is lower than 100°F (38°C), the control does not
operate the Boiler contact. Locate and repair the problem as described in 10K Sensors L630070. To clear the error
message from the control after the sensor has been repaired, press the Item button.
VIEW
MIX
The control is no longer able to read the mixing supply sensor due to a short circuit. In this case the control will
operate the mixing valve at a fixed output as long as there is a mixing demand. Locate and repair the problem as
described in 10K Sensors L630070. To clear the error message from the control after the sensor has been repaired,
press the Item button.

VIEW OUTDR
The control is no longer able to read the outdoor sensor due to an open circuit. In this case the control assumes an
outdoor temperature of 32°F (0 °C) and continues operation. Locate and repair the problem as described in 10K Sensors
L630070. To clear the error message from the control after the sensor has been repaired, press the Item button.

The control was unable to read a piece of information from its EEPROM. This error can be caused by a noisy power
source. The control will load the factory defaults and stop operation until all the settings are verified.
