Error Messages (continued)
MIXING SUPPLY SENSOR OPEN
(See fig. e)
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
floating action 3-way valve at a fixed position as long as there is a
mixing demand. Locate and repair the problem as described in
Installation - Step 7 (page 20). To clear the error message from the
control after the sensor has been repaired, press the Item button.
BOILER SENSOR SHORT
(See fig. f)
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 operates the Boiler contact as a boiler
enable (see section C). 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 Installation - Step 7 (page 20). To
clear the error message from the control after the sensor has been
repaired, press the Item button.
BOILER SENSOR OPEN
(See fig. g)
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 operates the Boiler contact as a boiler enable. 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 Installation - Step 7 (page 20). 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.
