Power and Switching cable – used to
power thermostats and drive output.
Grouping and Communication cable.
Communication cable can be used when units are used as individual PRT's for
heat/cool changeover. Please refer to page 13 and the Wiring Centre
Instruction Manual.
While the units can function as standalone PRTs or
Timers, installing this optional inexpensive
Communication cable allows the units to communicate
with each other. This allows a thermostat to assume
convenient remote control of a group. This brings
central control of features such as Time Control,
Holiday and Party functions as well as Frost Control.
The individual group members can leave or re-enter
group control at the push of a button.
Cable size 1.5mm 3 core for L,N,SL and 0.5mm twin for the communication.
