How does it work?
A small temperature sensor is located on the outside of the building, on a north facing wall. This is wired to the internal controls of the boiler and information about the outside temperature is sent to the boiler controller constantly.
When the temperature changes outside the boiler responds and starts to increase or decrease the radiator temperature to compensate.
This pro-active mechanism means that people inside the building won't even notice that the temperature has changed outside.
For example, when the outside temperature drops at night, more heat is lost through the walls of the building.
Because the outdoor sensor detects the fall as soon as it happens, the boiler is able to raise the radiator temperature and keep the inside temperature stable.
With a conventional system, the temperature is dependent on a room thermostat, which will only take effect after the inside of the building has become too hot or too cold.
In summary, weather compensation controls enable the boiler to respond to outside temperature changes and adjust the radiator output, to maintain a constant temperature indoors. -
Weather comp is absolutely pish imo but they want you to fit them im sure in england.

Been using the Honeywell EvoHome for over a year and think it’s great. Each room is individually controlled so I only heat the ones I use, when I use them. Controlled from and app on my phone or the main hub..
This is paired to a Viessmann Vitodens 200w 35kw system boiler and pressurised cylinder, we have also had a weather compensator fitted (only recently). The evohome / Viessmann is not openTherm compatible, hence why we have the weather compensator. It heats the house from a curve based on homes heat loss / outside temperature and target temp.
