Error Message Description
MIXING EXPANSION MODULE CONFLICT
A Mixing Expansion Module is connected to the Boiler bus. The Mixing Expansion Module
must be removed from the Boiler bus, or the bus must be changed to Mix 1, Mix 2, or Mix 3
in order to clear the error message. The error message self clears once the error condition
is corrected.
MIX 1 SENSOR SHORT CIRCUIT
Due to a short circuit, the control failed to read the Mix 1 supply sensor. The Mix 1 Supply Sensor
is connected to the Mixing Module. As a result, the control operates mixing device 1 at a fixed
output as long as there is a call for heat. Locate and repair the problem as described in the
Data Brochure D 070. The error message self clears once the error condition is corrected.
MIX 1 SENSOR OPEN CIRCUIT
Due to an open circuit, the control failed to read the Mix 1 supply sensor. The Mix 1 supply
sensor is connected to the Mixing Module. The control operates the mixing device 1 at a fixed
output as long as there is a call for heat. Locate and repair the problem as described in the
Data Brochure D 070. The error message self clears once the error condition is corrected.
MIX 2 SENSOR SHORT CIRCUIT
Due to a short circuit, the control failed to read the Mix 2 supply sensor. The Mix 2 supply
sensor is connected to the Mixing Module. The control operates the mixing device 2 at a fixed
output as long as there is a call for heat. Locate and repair the problem as described in the
Data Brochure D 070. The error message self clears once the error condition is corrected.
MIX 2 SENSOR OPEN CIRCUIT
Due to an open circuit, the control failed to read the Mix 2 supply sensor. The Mix 2 supply
sensor is connected to the Mixing Module. The control operates the mixing device 2 at a fixed
output as long as there is a call for heat. Locate and repair the problem as described in the
Data Brochure D 070. The error message self clears once the error condition is corrected.
MIX 3 SENSOR SHORT CIRCUIT
Due to a short circuit, the control failed to read the Mix 3 supply sensor. The Mix 3 supply
sensor is connected to the Mixing Module. The control operates the mixing device 3 at a fixed
output as long as there is a call for heat. Locate and repair the problem as described in the
Data Brochure D 070. The error message self clears once the error condition is corrected.
MIX 3 SENSOR OPEN CIRCUIT
Due to an open circuit, the control failed to read the Mix 3 supply sensor. The Mix 3 supply
sensor is connected to the Mixing Module. The control operates the mixing device 3 at a fixed
output as long as there is a call for heat. Locate and repair the problem as described in the
Data Brochure D 070. The error message self clears once the error condition is corrected.
BOILER SENSOR SHORT CIRCUIT
Due to a short circuit, the control failed to read the boiler 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.
