By JForrester 08 Mar 2023

With the nights getting colder, it might be time to start cranking up the heat!

a control panel

You may have noticed an Irus controller in your room - these are the control buttons for the heating.

The top arrow button increases the temperature and the heating level will be indicated on the screen

The bottom arrow button turns the temperature down.

There are 3 modes;

  • Frost
  • Setback
  • Boost range

Setback mode is active most of the time, this keeps your room at a constant comfortable temperature. If you want your room to be warmer, press the up arrow button to enter boost range mode.

Frost mode becomes active when your room is left empty for long periods of time.

The controller has a PIR (passive infra-red) sensor which tells the sensor what to do, for example, if you set the mode to boost range and leave your room for a long period of time, it'll switch back to setback mode to save energy.

Once you return if you need more heat simply click the up arrow button.
