Hello,
I'm new to the forum so apologies in advance for any newbie questions!
I'm looking to install 8x HR92s along with wiring up the BDR91 relay box to my Worcester Bosch Greenstar 30si boiler which currently has a DT20RF RF programmer attached on the front panel.
My plan is as follows:
1. Leave the DT20RF set to "always on" and leave the DT20RF connect to the boiler.
2. Wire the BDR91 relay box into the boiler using the following diagram from http://www.ultimatehandyman.co.uk/fo...t=73938&start=

Use 5 core 0.75mm cable like this: https://www.screwfix.com/p/time-3095...10m-coil/391pf
3. Connect the HR92s to all radiators except one of the hallway ones and the kitchen radiator (this has an old TRV are so doubt compatible with the HR92). These will act as bypass radiators.
Does this make sense?
Also, I have two radiator in the through ounge/dining room (one in each room) - do you set this up as one zone or two?
Many thanks!
