About Advanced Features & Operation

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 #11 and 12,
page 13).
When the CK1 and R terminals are shorted together, and the thermostat is
programmed for Unoccupied operation (step #12, page 13), the thermostat
will be forced into Unoccupied setpoints and the Unoccupied icon will appear
on the display.
Important Note: For control of multiple thermostats by one source,
refer to ‘Potential Phasing Problems’ on page 24.
Connect wires to a time clock or
other device to force the thermostat
into Occupied 1 or Unoccupied.
