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.

Remote Mounted Thermostat Installation

Units that are furnished with remote mounted

thermostats should be wired as shown in Figure 25.

Other considerations for this arrangement are as follows:

1. When wiring the low voltage plug and receptacle

disconnect, provide enough wire to move harness

out of the way for chassis removal.

Remote Wall Mounted Thermostats

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.

If secondary units are to be employed, see

connections in Figure 25.

Note: To allow Primary (Master) / Secondary (Slave)

operation, the primary board thermostat jumper must

be in the “T’stat” position and the secondary boards

must be in the “Sec” position.

The number of secondary units that can be

connected is limited to 32 units.

When using a programmable wall thermostat,

connect it to the terminal board remote thermostat

plug. Refer to the instructions furnished with the

chosen thermostat.
