KNX Heating Actuator 8-fold, 42SU MDRC, 24-230 V AC.
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 (230 V AC).
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 (230 V AC). Mains voltage failure detection with fault message object (230 V AC).
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).
