Hello I am new to Evohome and to this forum.
New Evohome install on old Vaillant thermocompact last week by local plumbing company. CH&HW relays and the rad valve heads. Specific plumber had installed Evohome on new builds in a previous job.
After I got home in the evening I set up Wi-fi which triggered firmware update after which it rebooted.
That night it had a comms error with the relays and the house was cold in morning.
Plumber returned and rebound hot water relay.
System has then worked mostly as expected but I had a suspicion it cycles boiler all night.
Last night I confirmed this two hours after last heat demand. System status shows 0% demand but boiler doing minimal one minute cycles with pump overrun.
Tested again this morning using the off setting and checking 0% demand and the same.
Any systematic troubleshooting advice from the experts I have observed posting here would be appreciated. I have pinged an email to Honeywell but I am sure it might take a while to get a response. I can do Evohome settings stuff but if it’s wiring I will call in installer to do. Many thanks!
Edit:
I forgot to say the house being cold was a boiler pump problem that was fixed. I also can now add that last night I checked and the relay green lights are NOT illuminated when the boiler is cycling so could this mean it’s not an Evohome problem?
