The 230 V thermoelectric valve drive is used to open

and shut valves in heating, ventilation and air

conditioning technology. It is controlled by a room

temperature control unit (230 V) with a two-step

output or pulse width modulation.

A large selection of valve adapters ensures that it

conforms perfectly to a range of valve bodies and

heating circuit distributors. The 230 V thermoelectric

valve drive therefore has universal applicability and is

suitable for a diverse range of systems.

De-energised - closed

The control mechanism of the thermoelectric valve

drive works with a PTC-heated expanding element and

a compression spring. The expanding element is

heated when the operating voltage is applied. After

the delay period has expired, the valve will open

uniformly. When the operating voltage is switched off,

the expanding element will cool down and, when the

idle time has expired, the valve will be closed

uniformly by the closing pressure of the compression

spring. The closing pressure of the compression

spring (90 N controlling torque) has been matched to

the closing pressure of commercially available valves

and holds the valve closed in its de-energised state.

First-open function

In the supplied state, the 230 V thermoelectric valve

drive is opened without current using the first-open

function. This makes it possible to operate the heating

during the shell construction phase, even if the

electrical wiring of the single room heating has not

been completed. When started up at a later stage, the

first-open function is automatically released when the

operating voltage is applied (for longer than 6 min), and

the 230 V thermoelectric valve drive is then ready to

function normally.

Functional display

The functional display of the thermoelectric valve drive

(all-round display) makes it possible to see the

operating status (valve "open", "closed" or in an

intermediate position) at a glance.

½Risk of fatal injury from electrical current!

All work on the device should only be carried out

by skilled electrician. Please observe the

country-specific regulations.

For the installation of a 230 V system, we recommend

the following cables:

Light plastic-sheathed cable: NYM1.5 mm²

Flat webbed cable: NYIF1.5 mm²

The valves are adjusted using a valve adapter, various

versions of which can be supplied for the most widely

used valve bodies and heating circuit distributors.
