E8.1124
Mixer module
System diagram E8.1124
Configuration
2 mixed heating circuits remoted by BUS or
1 mixed heating circuit and fixed value-/swimming
bath / DHW-control (LPS = 00)
With boiler control as mixer expansion module
The E8.1124 is for stand-alone-control too.
In this case you have to add the external sensor.
Without boiler control with 1 external sensor
Without boiler control as zone-control
Mixer module E8.1124
Electrical connection
~230 V Switching capacity of relays 2(2) A, ~250 V
! If E6.1111 should be replaced, please change
the wiring of the additional relay (plug VI) from
clamp 2 to clamp 1.
