oventrop Regumat Instructions D'installation page 12

The Regumat M3 and M4 are supplied with an actuator.
Models: Regumat with actuator NR 230 for 230 V
Regumat with actuator NR 24 for 24 V
The actuators NR 24 and NR 230 are used for the motorised actuation of Oventrop three- and four-way mixing
valves.
The actuators can be activated via any commercial control system with a three point output. If the actuator
rotates clockwise, the flow temperature increases until the limit stop of the actuator
is reached (supply opened, bypass closed). The flow tempera-
ture drops if the actuator rotates anticlockwise until the oppo-
site limit stop is reached (supply closed, bypass opened).

The angle of rotation is limited to 90°. Having reached the limit
stops, the actuator is switched off electrically and is without
current. In case of a malfunction of the control system, the
actuator can be converted to manual operation with the help of
an additional rotary knob.
Installation instructions for the connection to an Oventrop three-way mixing valve:
– Mount antirotation device (1) onto the valve body.
– Push adapter (2) onto the spindle of the mixing valve (3) until stop. Ensure flat surfaces on spindle and
adapter are aligned
– Set spindle of the mixing valve in such a way that the nose of the adapter points downwards in the direction
of the axis of the connection thread. In this position, the supply is closed by the spindle of the mixing valve
(bypass completely opened, cold).
– Place actuator (4) onto the shaft of the mixing valve.
– Place rotation indicator (5) onto the actuator as illustrated.
– Slip handle for manual setting (6) onto the shaft of the mixing valve with the arrow being in the blue zone (fac-
tory setting: Anticlockwise sense until stop, operating posi-
tion "A" automatic operation). Introduce and tighten screw
(7) together with the serrated lock washer.
Installation in intermediate position:
Factory setting misaligned – actuator has not reached limit stop.
– Place actuator onto the shaft of the mixing valve.
– Set operating switch to manual operation.
– Place rotation indicator onto the actuator as illustrated.
– Push handle for manual setting onto the shaft of the mixing
valve.
Attention: The handle can only be engaged easily in a snap-
in position. Do not use excessive force
Turn handle for manual setting to the left until stop.
Arrow of the handle is in the blue zone.
– Introduce and tighten screw together with the serrated lock
washer.
– Set operating switch to automatic operation.
