MIXING VALVE

The EU-L-4X WiFi board can operate an additional valve using a valve module (e.g. the EU-i-1m). This valve has RS
communication, but it is necessary to carry out the registration process, which will require users to quote the module number
located in the rear of its housing, or in the software information screen). After correct registration, individual parameters of
the auxiliary valve can be set-up.
➢ Information - allows viewing the valve parameters status.
➢ Register - After entering the code on the back of the valve or in the
the valve with the main controller.
➢ Manual mode – users have the ability to manually stop the valve operation, open/close the valve and switch the
pump on and off in order to control the correct operation of the devices
➢ Version - displays the valve software version number. This information is necessary when contacting the service.

register the new module).
➢ ON – temporarily enables/ disables valve operation
➢ Valve set temperature – for establishing valve set temperature
