– Burner starts subject to demand from the header temperature control (heating mode) or in case of
cylinder demand.
– Feed/heating circuit pump enabled as a feed pump (heating mode only). Not activated during cylinder
heating.
– Header temperature control (heating mode only)
– Input E2: Header sensor (heating mode only)
– In case of cylinder heating, the reference temperature is provided by the boiler sensor.
– Heating circuit with MM-2! see hydraulic schemes no. 16-52-018-003, 16-52-018-005 and
