Description
• Thermo-actuator, on/off in NC/NO versions with pinconnection cable ends.
• NC – Normally Closed. Deenergized closed, commonly
used on cooling valves.
• NO – Normally Open. Deenergized open, commonly
used on heating valves.
• Older ADAPT and CONTROL controllers only support

”First open”-funCtion
• At delivery, the actuator is set to the ”first open” function.
This means that the actuator is open when it is installed,
making it easier to pressure test and vent the water system.
• The function will be automatically disabled after the
actuator has been energized for approx. 6 minutes.
A clicking noise will be heard after which the actuator will change over to the NC mode and the normal
regulation function will begin.
Figure 1. ACTUATOR valve position indicator. The actuator’s cylinder shaped position indicator clearly shows the current operating
setting from all angles. The actuator is in closed position when the
indicator is at its lowest position, i.e. the same height as the enclosure. The actuator is in open position when the indicator is in the
raised position above the enclosure, i.e. the blue marking is visible.
