■ Solar circuit pump off:

When reaching the selected set tem-

perature "Tcyl set".

■ The solar circuit pump will start long

enough to enable this temperature to

fall by 5 K, if the collector temperature

rises to the selected maximum collec-

tor temperature "Tcolmax". The cyl-

inder temperature can then rise fur-

ther, but only up to 90 ºC.

■ You can select the consumer to which

the collector cooling function applies.

Delivered condition: This function

affects all consumers.

Note

Ensure the intrinsic safety of the solar

thermal system by accurately sizing the

diaphragm expansion vessel, even if the

collector temperature continues to rise

after the system has reached all limit

temperatures.

The solar circuit pump will be locked out

or stopped in case of stagnation or when

the stop temperature "Tcolemoff" (see

page 118) is reached. This prevents a

thermal overload of the connected com-

ponents.

solar control unit:
