USER INFORMATION
If there is no 230 V power supply for the module or one of its 230 V
components (e.g. plug-in connection has not been made), the relevant
components (e.g. pumps) will not be activated.
You cannot recognise this error on the module in question since the
LED and the control functions work independently of this power
supply. Check cable connections thoroughly before re-fitting controller
casings.
Function
The module logs on as a new
module FM455/CMC 900 or
FM457/CMC 920.
