BOILER SUPPLY SENSOR SHORT CIRCUIT
Due to a short circuit, the control failed to read the boiler supply sensor. When there is a call
for heat, the control no longer controls the boiler(s). Instead, the control provides a boiler
enable to the boiler’s aquastat or boiler control until the sensor is repaired. The control will not
operate the boiler contact if the Boil Minimum setting is less than 100°F (38.0°C). Locate and
repair the problem as described in the data brochure D 070. The error message self clears
once the error condition is corrected.
