Function is deactivated.
On
Function is activated.
When manual control is activated, the relays are no longer energized and deenergized
according to the control state, but are set to a predefined manual control state in
accordance with their functions (see table below). The relay outputs are set to a state
where heat is provided, independent of their hydraulic function. The solar plant remains
Off since there is a possibility of storage tank recooling via the collector. A relay
energized with manual control can be deenergized by an electronic control thermostat
(TR) or limit thermostat (LT).
Note!
In the case of manual control, mixing valve outputs Open/Close are not controlled.
The mixing valves should be manually driven to a suitable position.
