auxiliary relay that is installed, and you can actuate two other
components with the multi-functional module.
The following components can be actuated:
1.

5.6.9
Actuating the circulation pump according
to requirements
Note
The product's electronics provide the opportunity
to control a domestic hot water cylinder's circula-
tion pump as necessary (similar to an automatic
light unit for stairs). It is controlled using an ex-
ternal button (to be fitted on-site) that can be in-
stalled anywhere in the dwelling, e.g. in the bath-
room or kitchen. When the button is pressed, the
circulation pump starts up. The pump is switched
on again after five minutes. Several buttons can
be pressed in parallel. Irrespective of the external
control of the circulation pump, the "Control by
programmable time periods" function continues to
be possible when a controller is used.
Conditions
: Domestic hot water cylinder connected
▶
Carry out the wiring. (

▶
Connect the supply line for an external button using ter-
minals 1
(0) and 6 (functional drawing) on the X41
edge connector, which is supplied with the controller.
▶
Plug the edge connector into the PCB slot X41.
