INSTALLATION DIAGRAMS

System 1 - SOLAR HEATING WITH 1 STORAGE CYLINDER

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.

Optionally, sensors S3 and S4 can be used for metering purposes.

Sensor S3 can be used as a reference sensor for the storage cyl-

inder safety deactivation function (

OSEM

).

If the thermal energy metering function (

OHQM

) is activated, 

sensors S4 and 

VFD

 can be used as flow and return sensors.

If the drainback function (

ODB

) is activated, relay 2 can be used 

to activate the booster pump. The booster function (

OBST

) must 

be activated for this purpose.
