Remote Thermostat Control
The Remote Thermostat can be any thermostat
that can interface with an electronic thermostat via
RCWYBG terminals. The Control Selection jumper
must be in T’STAT position. During a call the remote
thermostat will pass R back to the controller on a
respective terminal. The push buttons on the touchpad
become inactive in the remote thermostat mode.
However, the control pad LED display will indicate the
mode of operation, and the room temperature.
Installation of Remote Mounted Thermostat
Units that are furnished with remote mounted
thermostats should be wired as shown in Figure 40.
Other considerations for this arrangement are as follows:
Remote Wall Mounted Thermostats
1. When wiring the low voltage plug and receptacle
disconnect, provide enough wire to move harness
out of the way for chassis removal.
2. If subbase is used, a small hole must be drilled and
grommeted in the subbase front to allow passage
of the low voltage wires.
3. If secondary units are to be employed, see
connections in Figure 40. The number of
secondary units that can be connected is limited to
32 units.
4. When using a programmable wall thermostat,
connect it to the terminal board remote thermostat
plug. Refer to the instructions furnished with the
chosen thermostat.
