Looking for some help, on the weather compensation aspect of the heating system.
WB Engineer and WB Technical all pretty rubbish, in that just set all setting to max so not that helpful.

thats the controller.
Page 36 shows the heating curve settings.
the controller has 4 input settings
Design Temp i have 54 deg c
Max Flow Temp i have 54 deg c
Room Infleunce i have 1K
Room Temp Offset i have 0k

does that look reasonable

controller now showing room temp of 20.5 Deg and heating on, set point is 21 deg.
photos showing screen info.

Strange- heating set for 6 am to 10 pm on weather compensation

Woke up 4am and heating was on, which it shouldn’t

125 kWh of gas on yesterdays experiment,
100kWh so far for today’s experiment.

No wonder you just use on-off programmer.

So reduced the set back temp last night to a good 4 or so degrees below the room temp so I know it never gets this low, the heating didn’t come on until 30 mins before the set on time so must have realised temps were falling and had to override the set on time.

Temps are more stable in the house as opposed to the on/off, warm/cold of the traditional on/off dumb stat when weather compensation is switched off.
