The control is no longer able to read the Boiler Supply sensor due to an open circuit. If the Boiler
Minimum setting is higher than 100˚F (38˚C) the control will close the boiler contact when there is a
call for heat in the system and the boiler temperature will be controlled by the boiler’s operating aquastat.
If the Boiler Minimum setting is lower than 100˚F (38˚C) the control will not operate the boiler contact.
Locate and repair the problem as described in the Data Brochure D070. To clear the error message
from the control after the sensor has been repaired, press either the Menu or Item button.
The control is no longer able to read the 10K 1 input because of a short circuit. The control will continue
to operate as if there was nothing connected to the 10K 1 input. To clear the error message from the
