activated. If the minimum operation time is not reached, the cleaning will not be
started even if the required number of shutdowns has occurred. To turn off the
„Minimum operating time without cleaning' option, set the parameter to „0h'.

contacts are closed and in case of emergency (e.g. boiler overheating). Selection of
„AUTO” setting means that central heating pump operation will follow regardless of
room thermostat.
