1. Installation

1.1 Mounting

• Attach the electrothermal actuator to the valve by means
of a union nut. The valve can be mounted in any position,
but the actuator must not face downwards.

The installation of the valve must be carried out in accor-
dance with the approved technical regulations. The installation
must be carried out by an approved technician! Pay attention
to the valid loacal regulations!
The connection has to be carried out in accordance with
the connecion scheme shown in the overview.
The cables of the actuator have to be connected to the relay
outputs of the controller:
• connect the brown line to the terminal with the phase.
• connect the blue line to the terminal with the neutral con-
We recommend fusing the individual devices. The cable sec-
tion should correspond to the valid local regulations at 220 V
operating voltage and should be at least 1,5 mm² at 24 V.
Important note: Operating voltage and control voltage
must be equal.

When several valves with actuators are used in one system,
the voltages must be in-phase.
Use a stuffing box screwing as a strain relief of the connec-
tion cable. Tighten the screwing after the installation has
been finished.
During routing of the cable, the connection cable
must not touch hot system components (e.g. radia-
brown
tor, pipes, etc.)
After the cables have been connected to the controller or
thermostat, the actuator is ready for operation.
