The electronic MA X! Radiator Thermostat has the
advantage over mechanical thermostat dials in that
it can protect against the threat of valve calcification

Routine descaling is factory-set to run on Saturdays
at 11 in the morning. "CAL" is displayed during routine
descaling; you can set the day of the week and the time
of day via the MAX! Software.
