The

COMPUTHERM

®

DF-330is an electrothermal valve actuator with 2-point control.

It is connected to a radiator valve or heating manifold with the help of a are nut, and

allows its opening/closing. The open or closed state of the valve is shown by the position

of the blue indicator on the face of the actuator. When the valve is closed, the status indi-

cator sinks into the housing of the actuator, and when the valve is open, it emerges a few

millimeters. The simple, electrothermal design is reliable and ensures stable operation

and low energy consumption.

The

COMPUTHERM

®

DF-330actuators have an automatic and a manual mode too. The

transparent dial on the front of the actuator can be used to switch between these modes.

In the automatic (AUTO; factory default) mode the actuator keeps the valve closed when

it is not supplied with the 230 V mains voltage, and it ensures its opening (~4 mm stroke)

within 4 minutes when supplied with 230 V. In manual ( ) mode, the actuator keeps

the valve in a partially open state, regardless of power supply (~2.5 mm stroke).

The

COMPUTHERM

DF-330 electrothermal actuator complies with the requirements of

directives EMC 2014/30/EU, LVD 2014/35/EU and RoHS 2011/65/EU.

CAUTION! Modifying the device involves the risk of electric shock or malfunction.

ATTENTION!Leave the electrical wiring of the product to a professional! Before instal-

lation, make sure that the device to which you want to connect the actuator is not con-

nected to the 230 V. Do not use pipe clamps or similar tools when wiring. Only use wires

with high heat resistance (e.g. silicone rubber) insulation. When installing the actuator,

make sure that it is protected against dripping water.
