ACTUATOR ‘STELLA’ 230 V NC FOR AUTOMATIC HYDRAULIC BALANCING
TECHNICAL DATA
APPLICATION
Operating voltage:
230 V~, 50 Hz
‘Stella’ – the intelligent autonomous 230 VAC NC electrothermal actuator for automatic adaptive hydraulic balancing of heating manifolds’ heating circuits in surface heating and surface cooling systems. Sensors on the supply and return lines measure temperature differences, and an algorithm continuously calculates the necessary temperature spread and the appropriate valve position. Normally closed and features a folding lever for easily unscrewing the thermostat valve or opening it manually when it is disconnected from the mains. Features integrated inflow temperature limitation. Combinable with every common tem- perature controller and terminal strip (except devices with switching element Triac).

BRIEF DESCRIPTION
§ Combinable with the commercial 2-point room temperature con- troller (electromechanical, electronic, PWM), except devices with switching element Triac § For heating and cooling systems § Features a folding lever for easily unscrewing the thermostat valve or opening it manually when it is disconnected from the mains § Temperature sensors suited for surface heating pipes made of plastic, metal or combinations thereof with an external diameter of 12 to 20 mm § Measures a heating circuit’s outflow temperature § The range of setpoint temperatures Stella calculates is variable and dependent on user behaviour and the system’s environment § The valve can be adjusted to any desired position between OPEN and CLOSED and set to remain in that position. § An expansion element and a stroke measuring system are needed to position the valve stroke.
