6. A field-supplied 0 to 10 vdc signal to the 50XJ unit may
be used to reset the supply-air temperature.
The reset will be taken off the supply air set point
configured in the controller. The reset range can be
changed by adjusting the High Conversion Endpoint
value of the custom voltage input to a value other than
20. For example for 10 degrees of reset change the Hi
input value to 10. This may be found by pressing 7
from the Keypad. RESET will be the second
custom voltage input point in the controller. The first
will be CSMUX, which is the compressor status multi-
plexed input. Press
