Application

Universal application for controlling mixing valves DN 20 to DN 50. Perfect solution for automated operation of water-based heating and cooling systems. Suitable for mixers from AFRISO, ESBE (except VRG), Seltron, Somatherm, Hora, WIP, PAW, LK, BRV, IMIT, IVAR, HOVAL and OLYMP. Please enquire for other mounting kits.

Description

Compact, silent actuator with an angle of rotation of 90°. Can be switched over from automatic mode to manual mode. A rotary knob with scale allows for fast and accurate manual adjustment of the mixing valve. Two yellow LEDs indicate the direction of rotation of the actuator, the red LED the switching state of the microswitch (ARM 443 only). Microswitch for controlling a pump. The pre-assembled connection cable with colour-coded wires simplifies installation. Two scales with "0 to 10" for horizontal installation and "10 to 0" for vertical installation are included for maximum flexibility. The integrated protection unit keeps the actuator and mixing valve from blocking for a long service life. A mounting kits allow for adaptation to mixers from a wide variety of manufacturers. ARM is maintenance-free.
