Systems

The SOL3-7 provides 117 different hydraulic systems. These differs in basic system components and extentions.

Basic system components Extentions

•number of collector arrays,

•number of storage tanks,

•switching between collector arrays and storage tanks using

valves or pumps,

•internal (or non) or external heat exchanger

•heating circuit,

•auxilary heater,

•circulation pump

The schemes below are only schemes, without any kind of basic valves and security equipement. A system scheme is

identified by a explicit system schema indicator (e.g. I o 2. I.0)

Check and set party mode

Using the Party mode function, the controller continues or activates the day mode during the time when the party timer is

active, regardless of the programmed times-of-use. The activation of the party mode (count down) starts with turning the

rotary switch to any operating mode position (e.g.information level). When the party timer has elapsed, the party mode timer

is reset to 00:00.

The party mode counts down in steps of 15 minutes and ranges up to 48 hours.

Push rotary pushbutton;

Confirm positioning value of valve M1

Turn rotary pushbutton;

Display: further output

Return the rotary switch to normal position (information level).

The manual mode now is deactivated.

Display: Time

Note:

The outputs of the controller are not affected by simply turning the rotary switch to (manual level). You have to enter a

positioning value or activate/deactivate the pumps to configure the outputs.

The frost protection does not work during the controllers manual mode !
