Please could someone clarify the "Loss of Communication Setting" option (parameter 7LC) on the CM927. I understand the principle in that if communication is lost between the two units then fail-safe keeps the relay and hence boiler off as one option (0) but what exactly are the time periods used when set as 20% on 80% off (1)?
Is this 20% "on" in an hour/day/week etc? I know the total "on" figure will be the same i.e. 20% "on" in an hour will be the same as 20% "on" in any multiple of one hour but does anyone know what the base-line time is against which the 20% is calculated?
Hope this makes sense!
Thanks
