If the iQ Ceramic was purchased after 16th October 2024, it does have a Boost Mode.
You can set the radiator to heat at any temperature between 7-30℃ at 1-hour intervals for up to 24h.
When triggered, an animation will play along the side of the display, the rocket icon will be flashing, and the boost temperature and time will alternate on the screen.
This can be enabled in manual and program mode by pressing and holding down the rocket symbol.
You can cancel this by pressing and holding the rocket symbol or by pressing standby.
Please note: By pressing standby, you will put the radiator in standby and will need to turn it on again. This can't be overridden.
