Ways of adjusting the pump flow
The circulation of the heat transfer liquid by the pump can be divided between internal (INT) and external (EXT)
with the aid of the selector switch at the front on the control head (flow distribution). This adjustment is continu-
ously variable and is also possible at any time during operation.
The adjustment between internal and external circulation is only practicable when an external consumer is
connected. You need a pump connection set for this. This set is included as standard with cooling devices and
with the heating devices E 4G and ET 15 G. With immersion thermostats and the other heating thermostats the
pump connection set is available as an accessory. (
Ì
With a pure bath application the selector switch has to be set to INT.
