Dry Contact for Alarm Signal
The C1050 has an analog input which can be designated as an alarm signal input. Please refer to Figure 9 to see how to
correctly connect it. To signal an alarm, the contact must be closed. Closing this contact will prevent the use of the com-
pressors, either in heating or cooling. Auxiliary heating will still activate as required.
