Hi
Looking for a bit of help...
I've just finished converting my S Plan+ system to EvoHome, but I'm having problems with the radiator values not switching the CH BDR91 value. The boiler fires (controlled by the Opentherm Bridge) but the CH zone value remains closed? The BDR91 controlling the CH value works fine when tested manually.
For background:
Boiler controlled via Opentherm, switched live discounted. This appears to work fine. EvoHome configured for Opentherm Boiler control
Ground Floor, and 1st Floor CH valves linked together. Testing the attached BDR91 manually the valves on/close as expected.
EvoHome hot water kit connected. Setup configured as a 2/3 port valve, with both HW and CH values binded. This appears to work fine. When hot water is needed the HW valve opens etc...
14 HR91 valves attached to radiators
For testing purposes 1 radiator valve zone configured and binded to 1 of the HR91. Testing, this calls for heat, boiler comes on, however the CH valve doesn't open (green light remains off).
Any help would be greatly appreciated. I assumed that when a HR91 called for heat, it would open the CH valve setup during the Stored Hot Water setup?
Many thanks
Dan
