Controller connection FC3.10
The following illustrations show how to connect the 2-way zone valves (switch valves)
electrically to the controller, and how to connect the controllers with each other in order to
establish a communication between them.
WARNING
Risk to life and limb due to electric shock!
Prior to commencing electrical work on the controller, pull the mains plug
and make sure that a restart is not possible.
Only after completing all installation work, plug the mains plug of the
controller into a socket. This avoids an unintentional start of the motors.
