Remote Thermostat With Secondary Units - McQuay PDAE Installation & Maintenance Data

Remote Wall Mounted Thermostats
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.

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 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.
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.
