Manual operation

During commissioning or in the event of fault, manual operation enables the heating
plant to be controlled manually.
Using the 2 setting buttons, 2-port valve Y1 in the primary return can be driven into any
position. The heating circuit pump and d.h.w. pump(s) will run.
The controller's display shows the flow temperature (sensor B1).
With plant types no. 4 through 6, the display changes to the d.h.w. flow temperature
(sensor B3 / B71), if the heating circuit is switched off (operating line 52), but the setting
buttons still act on 2-port valve Y1.
In manual operation, the control functions do not affect the relay outputs.
