About Advanced Features & Operation

26

DRY CONTACT SWITCH - 

This feature allows an external device such as a 

Central Time Clock, Occupancy Sensor, or a Telephone activated device to 

force one or more thermostats into an Unoccupied mode 

(steps #14 and 15, 

page 21-22).

 

When the CK1 and R terminals are shorted together, and the thermostat is 

programmed for Unoccupied operation 

(step #15, page 22)

, the thermostat 

will be forced into Unoccupied setpoints and the Unoccupied icon will appear 

on the display.  

Note:

 

The thermostat must be in Program On mode for this feature to have any 

effect. 

       

Important Note: For control of multiple thermostats by one source, 

refer to ‘Potential Phasing Problems’ on page 32.   

Connect wires to a time clock or 

other device to force the thermostat 

into Occupied 1 or Unoccupied.
