SELECT SENSOR

The user may select the sensor which will provide temperature readings for the cascade.
5.

VOLTAGE

If a 0-10V contact has been selected for the cascade, the user may configure the contact operation parameters:
Pre-set temperature bottom - if the calculated pre-set temperature is lower than this value, the voltage equals
•
0 V (also in case of heating need).
Operation parameters - the voltage depends on the pre-set range
•
The example concerns the following parameters:
Minimum temperature = 15°C
•
Minimum voltage = 2V
•
Maximum temperature = 30°C
•
Maximum voltage = 5V
•
According to this formula, the voltage should increase by 0,2V every 1°C of the pre-set temperature (3:15 = 0,2).
•
Voltage – this function is used to set the contact voltage.
6.

MAIN BOILER

If Main boiler option is selected in a given contact (optional), in every operation mode this contact will be enabled as the
first one and disabled as the last one. Only in Heating need mode, when all selected circuits report no heating need, all
contacts will be disabled at the same time.
7.

RESET MOTOHOURS

It is possible to reset the motohours for all contacts: Fitter's menu > Cascade > Reset motohours.
8.

FACTORY SETTINGS

This function enables the user to restore factory settings of the cascade algorithm.
