Gloworm ultracom 38 cxi ebus connection
hello all, first time posting on this forum so please have patience.
I have had a tado system for about 3 years now (v3) all has been working fine. I have just changed the extension kit which is downgraded to a EK01-TC-UK-03 to enable the ebus connection, I have connected 230v supply and ebus + and - to the receiver and + and - to the ebus boiler connection, extension has been paired to bridge and is showing connected, settings have been modified in wireless room stat, but when calling for heat through the app no heat is called to the boiler. the firmware version on the extension is 42.6.
Is there something that I am missing.
