John, I am not sure whether your screenshot is for your thermostat, but it is exactly the same for mine. 6 cycle ph, 1 minute min ON time.
The way I think about this is that a good thermostat should be able to monitor the outside temp and learn/so anticipate the heat loss of the house and work around it. In the real world I do not know how closely my existing thermostat is able to do this and whether there is a sizable margin for improvement or it is good enough. In the end my boiler is an on/off thing which by default means its control is not precise.
That info is from your stat, cant find any info from Honeywell. All these "clever" control systems like evohome will constantly cycle the boiler on and off even when the heat demand is > than the boilers minimum output to give pinpoint temperature control. Weather Compensation is best utilized IMO by controlling the boiler target temperature but the boiler has to be able to use this.John, I am not sure whether your screenshot is for your thermostat, but it is exactly the same for mine. 6 cycle ph, 1 minute min ON time.
