Just trying to understand my Eco RF 36, and hope the brains trust here can help...

It is installed as a System boiler with a 300L cylinder (5 showers, 12 radiators), and an on/off thermostat (with smart TRVs). TBH, I am not 100% sure what 'plan' it is, but there are two solenoid valves, and the system __seems__ to provide heat to CH or the cylinder, but not both; so S-plan?

It has been working 'OK' since July.

Questions (I have tried to read the manual):

1) sometimes the service display (the single digit display above the service button) show a single dot, in addition to the operating mode (and sometimes not) - what does that signify?

2) when responding to a CH call for heat, the system has a propensity to go to mode 1 when I would have thought it should have stayed in mode 5. There is no bypass radiator, but there is an external ABV. Can I adjust something in the parameters, or just I just use a bypass radiator?

I am hoping to avoid a bypass rad, because I found that the room with that radiator was always too hot.

3) I have the InTouch capability & can turn 'Use Internet outside temperature' on & off - this changes the temperature display from 85 to (say) 55, but appears to do so for both CH & HW. How do I get it to do so for CH only?

Non-default settings are (AFAICT):
1 - 3 (heating only, default is 0)
3 - 85 (Max. CH power set, 60)
3. - 85 (Max power CH-pump, 80)
4 - 100 (Max DHW power set, 99)
c - 25 (Minimal CH rpm, 30)
c. - 60 (Min capacity modulating pump, 40)

Its ok, but the "problem" is its a festive period and most are with their families, and not to mention some of our best most knowledgeable plumbers / heating engineers no longer post. :cb

Working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe?

That sound like a sad story - what happened?

Looks like I'm going to have to call Intergas myself, and there's no way they're gonna tell me what that dot means on the service display...
