9.10.5 OPERATION AREA - ACTIVATION OF THE AUXILIARY ELECTRIC HEATER AND BOILER (Plant circuit water
temperature sensor is not enabled)
The possible configurations of the parameters related to auxiliary heaters are listed below in the tables 1, 2, 3 and 4, that are
divided by areas of operation (the columns of the items "MODE" and "rxx" parameters indicate the operation mode and the
possible values of the parameters for allowing the auxiliary electric heaters to act according to a predefined order of intervention,
when the unit is running in a certain type of operation; several modes and values of the parameters can be alternatively selected
and they are reported in the same cell separated by the symbol "/").
