CVHE-SB-32A 58
UCP2 accepts an isolated contact closure input suitable for customer connection to put the unit
in either AUTO or STOP from a remote device. This input has priority over the unit switch when
the unit switch is in AUTO. This input does not have priority over the unit switch when the unit
switch is in STOP. The input is closed for external AUTO operation and open to put the unit in
external STOP. The external stop is a friendly shutdown, i.e. the chiller will unload before the
stop command is given.
The External Auto-Stop input is located on Chiller module terminals J5-1 and J5-2.
