Hi guys, this looks a great place for EvoHome advice, I wonder if somebody could point me in the right direction?
We've recently moved house and had a new heating system installed - standard Worcester gas boiler, unvented tank, S-plan system, 2 x BDR91's one for hot water, one for heating and 21 radiators. Each BDR91 also fires the boiler when it's engaged.
The plan is to fit 16 of these radiators with HR92's, 4 with standard TRV's (in the hallway, don't need them to be able to call for heat) and one in the En-Suite that has no TRV .
So far, our installer has fitted the system and he has left us with the EvoHome controller running in a single-zone thermostat mode as I thought adding a bunch of HR92's and setting up some zones would be straightforward enough (my background is software/firmware & hardware).
However, on installing the controller, he had great difficulty getting it to control the BDR91's and had to make 3 calls to Honeywell to get it working correctly so I'm now left in a position of being a bit worried about re-configuring and losing our heating system and would like some re-assurance / advice.
He didn't have any problem with communication (although Honeywell made him relocate the 2 BDR91's to be further apart), but whatever way he had the bindings set up, whenever he bound the hot water and the boiler relays then ran the RF Comms test for the hot water, it would flash the red lights on both BDR91's - is this correct or is this some form of double-bind that has been accidentally configured? We'd get the same when testing the hot water through the RF Comms.
I'm not sure how he corrected this as I wasn't in the house that day, but he said it was to do with re-setting the controller up from scratch, then deleting the first zone and re-adding it. It's all now working, but when I look at the System Summary it says
Stored Hot Water - No Devices Bound
Living Room - Zone valve, Evotouch Sensor (so he has the boiler BDR91 configured as the Zone Valve and is using Controller as thermostat with no HR92s)
I'm not sure how it's calling for hot water, but it does?
I added a zone that appears as:
Study - Radiator Valve
But this zone is unable to call for heat - from reading around, I think this is because the controller is in single-zone mode. I need to find the best way to set this up for the 9 zones I require but I am kinda worried as there's no way that I can see of recording all the settings / backing up the configuration to be able to get back to where I am now if I mess up.
I've gone through the Honeywell online training, just hopeful somebody could explain why the RF Comms was working the way it was (both BDR91 flashing on test), and what way the binding should be configured to allow me to get the zones programmed in so they can all call for heat.
I really miss a "proper" manual for this thing, like explanations of which specific bindings are used in which circumstances. I *think* being an S-Plan, even though I have a BDR91, I shouldn't be binding it as a "Boiler Relay" ... something about because mine was a Connected Thermostat Pack and a Hot Water Kit, it should be pre-bound, but I'm not positive about that
Any advice / links to great articles that I haven't yet found would be greatly appreciated!
