2 Product information
2.1 Intended use
The actuator is suitable for use in connection with the following basic
units models:
n1246
n1246.1
n1247
n1247.2
n1247.3
n1247.6
Since the combination with electronic components by other manufac‐
turers has not been tested, proper function cannot be ensured in this
case.
2.2 Product description
2.2.1 Functions
The actuator opens or closes the valve of the manifold, depending on
which signal the room thermostat transmits to the basic unit.
The power-actuated valve regulates the flow volume in the heating cir‐
cuit and is controlled and supplied with power by the basic unit via
cable connection.
The actuator is suitable for heating and cooling mode.

3 Handling
3.1 Transport and storage
Observe the following with transport and storage:
nAvoid heavy blows and vibrations.
nStore the components in a clean and dry place.
nDo not remove the components from the packaging until immedi‐
ately before use.
3.2 Mounting the actuators
Mounting preparation
DANGER!
Danger of electric shock due to electrical current
An electric shock can lead to burns and serious injury and
even death.
– Work on the electrics may only be carried out by trained
electricians.
– Always de-energise the connection line before work is
commenced.
Components required
nActuators – Number corresponding to the heating circuits to be con‐
trolled.
Set the actuator on the valve body with the connection cable facing
backwards, and hand-tighten the connection screw fitting.
CAUTION!
Damage to the actuator
Excessive tightening of the connection screw fitting may
damage the actuator.
– Tighten the connection screw fitting by hand only. Do
not use a pipe wrench.
