I've moved into a flat with three new storage heaters all linked to a
central control panel.

The one small storage heater that does not have a 'boost' button I
have no trouble with.

The other two are quite curious. The larger one only seems to come on
(and annoyingly with the fan) if I press the boost button. It won't
work in 'normal' mode.

The medium sized one always seems to be on boost mode - i.e. fan
assisted which wakes me up every morning at the alloted time.

Is there a way to get the two with boost settings to work normally
without their fans coming on?

Regards,

Gwyn
