Some options are only revealed if the user has Smart+ available.

The ability to add tight control over temperature Range. There is a range from 0 degree to 5 degrees of tolerance, this relates to the amount of tolerance higher than set temperature only and the system will not normally go below the set temperature. I have found that with our home running with 22.5 degrees C as our preferred setting, the 0 degrees setting holds the tolerance to - 0 and +0.6 degrees above our setting. I believe that each additional degree of tolerance permitted will add just that to one’s preferred setting. We are very fussy so the 0 degrees is our setting. Homely have explained this facility as ‘the wider the range, the greater economy may be achieved if the heat pump could benefit from an anticipated drop or rise in OAT by ‘riding through’ the change should a change in TOU rates occur’. As I am running on battery outside of the cheapest Cosy hours, this facility doesn’t really have any value for me.

Another option is ‘Cool Night Mode’ which ‘Restricts Pre-heating Overnight’ they say. I have toggled this option several times but have noticed no difference, whether I had an overnight set back or not. YMMV on this facility but I could not feel any difference in temperature, nor could I see any difference in the heat pump running behaviour when I view the Dashboard graphs. (Readers should please bear in mind that my limited sight may not allow me to see any subtleties in the graphs though).

Thirdly, I made mention above of set back and using a setting of 2 degrees lower during the night, this setting does not appear to materially affect the room temperature. It could be that our insulation is keeping the temperature from dropping significantly but, as when I look at the dashboard graphs, the temperature does not drop and the heat pump does run at times during the setback period though the node is indicating that the house is still above the minimum temperature that the set back should allow, I am unsure of efficacy. 

My conclusion is that Homely control ensures that if the heat pump has been sized correctly, there is very little chance that the home will ever drop significantly below your desired comfort level. Comfort level, once set will always meet your requirements and if, like us, you are intolerant of a wide range of variation, it is possible to hold variations within that +0.6 degrees of your target.

Regards, Toodles.
