(L1) : Live signal (for Normal* Closed type) from PCB to
mixing valve
(L2) : Live signal (for Normal Open type) from PCB to mixing
valve
(N1) : Neutral signal from PCB to mixing valve
*Closed = NOT Mixed
Step3. Insert the temperature sensor to 'CN_MIX_OUT' (Brown) of the main PCB as shown
below. The sensor should be mounted correctly to outlet pipe of mix kit water pump as
shown below.
