System 2 - SOLAR WATER HEATING WITH SUPPLEMENTARY HEATING

The controller calculates the temperature differential between

collector sensor S1 and storage cylinder sensor S2. If the differ-

ential exceeds or is equal to the set activation temperature dif-

ferential (

DT O

), relay 1 activates the solar pump and the storage

cylinder is charged until the deactivation temperature differen-

tial (

DT F

) or maximum storage cylinder temperature (

S MX

) is

reached.

Sensor S3 is used for the thermostat function for supplementary

heating, activated by relay 2, or for excess heat dissipation when

thermostat activation temperature (

AH O

) is reached.

This function can be combined with three adjustable time

bands.

Sensor S3 can be used as a reference sensor for the thermal dis-

infection function (

OtD

) or for the storage cylinder safety deacti-

vation function (

OSEM

Optionally, sensor S4 can be used for measurement purposes. If

the thermal energy metering function (

OHQM

) is activated, sen-

sors S4 and

VFD

can be used as flow and return sensors.
