And the final link is the wiring diag for the PRT-WTS.
My thoughts are: Using the existing wires, L & N are obvious, and keep the live loop between L & COM. The only wire which gives me concern is the Brown wire currently in terminal 3; should this be the S/L connection going to NO1 on the PRT?
Also, because this is thermostatically controlled, are there additional connections needed to allow for thermostat switching on/off? If so, I'll need to get a sparky in for that. Hoping its just a straight swap out though.
