Seeking advise on Weather Compensation

Bucki

Hello

I have a system boiler: Ideal Vogue Max and the set max temp is set to 60c because I also have a cylinder water tank.  The thermostat is Ideal Halo System Wifi which is connected to the WiFi which apparently uses the local weather forcast for the weather compensation part which I am not quite following how it works and what benefits... 

So, let's say today is 10c outside as per weather forecast whilst the room temperature is 18c in the room, as per thermostat.  How is weather compensation helping here? What is the aim of the game of it ... what am I expecting?

If I set the thermostat to 20c, what will weather compensation actually do on the boiler?
Will it make the boiler work less harder to reach the 20c temperature? Or will it ensure the Flow and Return temperature are kept within a specific temp range?

I am lost... please enlighten me and advise.
Appreciate your support.

Weather compensation adjusts the boiler’s flow temperature based on outside conditions. At 15°C outside it uses a lower flow temperature because the house loses heat more slowly than at 5°C. You still reach 20°C, but with steadier running and better efficiency in use of gas. The thermostat sets the room temperature; weather compensation sets how hot the radiators need to be.

The boiler ignores weather compensation when heating the hot-water cylinder. That part of the system is controlled by the cylinder thermostat and your programmer.
