MANUAL MODE

This option enables the user to enable/disable a given contact permanently.
14.

OFF

This function enables the user to deactivate the additional contact altogether.

IV. 0-10V CONTACTS

Voltage modulation from 0 to 10V is performed with the use of two 0-10V voltage outputs.

ACTIVITY

This option is used to select the operation modes of a given contact. It may operate in summer mode, in remaining
modes or in both cases.

HEATING NEED

Heating need - this algorithm is based on the readings from one selected temperature sensor.
Voltage modulation will start when the selected sensor temperature drops below the highest pre-set value reduced by
the hysteresis value of the selected circuits, with a valve or DHW or an additional contact (after the algorithm is selected:
central heating pump, additional heat source, buffer, DHW buffer). Modulation is carried out according to the operating
parameters where the voltage for a given pre-set temperature is defined as well as the voltage surge.
Operating parameter - the current voltage depends on the pre-set range.
