Error Displayed Description of Error
The control is no longer able to read the boiler sensor due to an open circuit. If the Boiler Minimum
setting is higher than 100
°F (38°C) the control closes the boiler contact when the mixing device starts
to operate. The boiler temperature is limited by the operating aquastat. If the Boiler Minimum setting
is lower than 100
°F (38°C) the control does not operate the boiler contact. Locate and repair the
problem as described in the Data Brochure D 070. If the Boiler Sensor was deliberately not installed,
set the Boil SENS item to NONE. To clear the control after the sensor has been repaired, press either
the Menu or Item button.
The control is no longer able to read the Mixing Supply sensor due to an open circuit. In this case, if
the Boil SENS item is set to SUP, the control will operate the mixing device at a fixed 15% of output
as long as there is a Mixing Demand. If the Boil SENS item is set to RET or NONE, the control operates
the mixing device at a fixed 30% of output as song as there is a Mixing Demand. Locate and repair
the problem as described in the Data Brochure D 070. 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 Mix Return sensor due to an short circuit. If the MIXING item
is set to FLOT, the control will operate without
∆T protection of the slab. If the MIXING item is set to
VAR, the control operates the snow melting system as required. In order to provide ∆T protection,
the control periodically shuts off the injection pump and uses the Mix Supply sensor to determine the
Mix Return temperature. Locate and repair the problem as described in the Data Brochure D 070. 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 input because of an open circuit. The control will continue
to operate as if there was nothing connected to the 10K input. Locate and repair the problem as
described in the Data Brochure D 070. If a 10K sensor was deliberately not installed, set the 10K item
to NONE. To clear the error message from the control after the sensor has been repaired, press either
the Menu or Item button. 10K
≠ NONE
The air sensor in the RTU is being read as a short circuit. The RTU will continue operation using all
remaining sensors. If all of the sensors are unavailable, the control will continue to operate as if the
RTU was not connected to the control. This error message can be cleared once the sensor has been
repaired. To clear the error message from the control, press either the Menu or Item button.

The Remote Sensor 1 attached to the RTU is being read as a short circuit. The RTU will continue
operation using all remaining sensors. If all of the sensors are unavailable, the control will continue to
operate as if the RTU was not connected to the control. This error message can be cleared once the
sensor has been repaired. Locate and repair the problem as described in the Data Brochure D 070.
