Product features
Fields of application The actuator is particularly suitable for utilisation in outdoor applications and is
protected against the following weather conditions:
- UV radiation
- dirt / dust
- rain / snow
- Humidity
Parameterisable actuators The factory settings cover the most common applications. Single parameters can be
modified with the ZTH EU or the Belimo Assistant App.
The Belimo Assistant App simplifies commissioning and parameterisation via Near
Field Communication (NFC). Moreover, it provides a variety of diagnostic options.
Simple direct mounting Simple direct mounting on the butterfly valve. The mounting orientation in relation to
the butterfly valve can be selected in 90° (angle) increments.
Manual override The valve can be manually operated using a hand crank. Unlocking is carried out
manually by removing the hand crank.
Internal heating An internal heater prevents condensation buildup.
Thanks to the integrated temperature and humidity sensor the built-in heater
automatically switches on.
High functional reliability The actuator is overload protected, requires no limit switches and automatically stops
when the end stop is reached.
Combination valve/actuator For valves with the following mechanical specifications in accordance with ISO 5211
F07:
- Square stem head SW = 17 mm for form-fit coupling of the rotary actuator.
- Hole circle d = 70 mm
Flexible signalization The actuator has one auxiliary switch with a fixed setting (10°) and one adjustable
auxiliary switch (0...90°).

Operating controls and indicators
!
Note Perform settings on the actuator only in deenergised state.
1Gear disengagement
Opening the manual override cover and adjusting the hand crank.
Manual override is possible.
2Manual override control
Turn the hand crank until the desired switching position A is indicated and then remove the
crank.
3Auxiliary Switch
Opening the auxiliary switch adjustment cover and adjusting the hand crank.
Turn the crank until the arrow points to the vertical line
4Terminals
Connect continuity tester to S4 + S5 or to S4 + S6.
If the auxiliary switch should switch in the opposite direction, rotate the hand crank by 180°.
