3. - Operating modes
In menu “3. Operating modes” the cont-
roller can either be switched to automatic
mode, turned off, or placed in a manual
operating mode.
The menu is closed by pressing “esc” or
selecting “Exit operating mode”.
Automatic mode is the normal operating mode of the controller.
Only automatic mode provides proper controller function taking into account the
current temperatures and the parameters that have been set!
3.1. - Automatic
Operating modes
3.2. - Manual
The relay and thus the connected pump, valve or heating rod are switched on and
off manually by pressing a key, with no regard to the current temperatures and the
parameters which have been set. The measured temperatures are also shown.
3.3. - Off
When the operating mode “Off” is activated, all controller functions are
switched off. This can lead, for example, to overheating of the solar
collector or other system components. The measured temperatures are
displayed even when the controller is Off.
Warning
Danger
The manual mode is intended to be used by a technician when
commissioning or checking the system. Activating manual mode in
current operation can lead to system damage or overheating of water in
the hot water storage tank!
Never select other mode than automatic without a reason. Long-term operation in
manual mode may lead to collector or storage tank overheating and limiting the lifetime
of solar fluid and other solar thermal components!
