    A T50 rad, assuming a room temp of 20C with a flow temp of 75C will require a return temp of 65C to give its rated output, it will...

    If the flow temperature is up to its target temp and the boiler is running at 50% output then the heat demand is 50% of the boilers...

    Yes John, many thanks for all your replies.

    Run this past me again please. WB say...... . If the burner is lit for a longer duration than the anti-cycle time, then this element...

    Target flow is 45C, ACT 12 mins and Hysteresis is 7C. No problem at all getting to room temp of 19C although it does take a couple of...

    Got it now, thanks, I think. Just to be clear, what are your current settings of Target Flow temperature and antcycle ACT time and your...

    If I set it at 2C from an initial obviously long burn then the 10 minute ACT is fulfilled so the boiler would wait for the 2C drop...

    A little clearer now, if you set the hysteresis at something daft like 2C, will the boiler just stay OFF for the (10 minute) ACT time or...

    It starts from scratch again. It seems very different than say, the Vaillant anti cycle mode. If I set 10 mines ACT and the boiler runs...

    Find a bit difficult to understand this, you set 2.3B to 10 seconds, the boiler may run for only 3 minutes so this leaves minutes of of...

    I thought the anti cycle time would be as stated below, the amount of time between stops and starts?. The hysteresis function is a nice...

    Very informative, thank you John. It's really trying to find the happy medium. When I was trying the flow at 55c (which still should...

    Not quite range rating as this only affects the maximum boiler output but will result in a longer run time, also the minimum Off time...

    A run time of 3600 decs is bordering on constant running, gas fired boilers have a very small HEX volume of ~ 2L or so, so will refire...
