Hi there,
I’m hoping someone can point me in the right direction; sorry, it’s another room stat question!!
I upgraded my motorised Hoorstman 423 Diamond programmer with the Salus EP200 and also added a RF room stat (the Salus RT300RF) as I did not have room stat control before, just boiler on/off at selected times.
Although I believed I carefully noted down all the connections prior to disconnection, the addition of the RF room stat wiring has thrown me somewhat.
My system is gravity fed hot water with pumped heating (there are no motorised valves). I initially wired up the programmer first in this manner (please note – Neutrals and Earth removed for clarity):
Pump ‘Live’ to T4 on the programmer and Boiler ‘Live’ to T3.
This seems to work fine, but is the following the correct wiring/changes to install the room stat:
Run permanent feeds from programmer’s L & N to receiver L (not ‘live in’?) & N. Run wire from ‘Live in’ of receiver to T2. Move pump live from T4 and also wire to T2.
Run wire from connection on receiver SL(on) to T4 of the programmer?
Does this appear correct?
Final thing; do I need to keep the link between the permanent live and the live in connections on the receiver?
Thanks for any help anyone can offer.
Jon.
