The thermostat can be connected to a remote system or remote switch.  A signal can be sent from the remote

this mode, setup item 01 - "Communications mode" must be set to 24.   
 
Run a two-conductor wire from the remote system or remote switch to the thermostat location.  Make the 
connections using supplied wire splices - See Figure 11.
