KNX Heating Actuator 4-fold, 2SU MDRC, 24-230VAC.
✔ Heating Actuator to control electrothermic valve drives. LED indicator for each channel.
✔ New generation with extended functionality. Each channel controls up to 4 electrothermic valve drives (230VAC).
✔ Free assignment of the outputs to the controller channel. Controllable with 1 Bit (Switching/PWM) / 1 Byte actuating variable or direct control with temperature value via KNX bus.
✔ Integrated PI temperature controller (Heating and Cooling). Comfort-, night- and frost protection.
✔ Summer-/winter operation. 1 Bit +/-, 1 Byte or 2 Byte absolute object to set the given value.
✔ Setpoint values are stored at bus voltage failure. Emergency operation if cyclic actuating variable fails.
✔ Overload protection with fault message object (230VAC). Mains voltage failure detection with fault message object (230VAC).
✔ Objects for heating request and cyclic movement of the valves. Comprehensive scene functions. Compatible with many visualisations. Minimum flow temperature.
✔ Diagnostics for each channel with 14 Byte plain text object. Quick application download (long frame support for ETS5).
