KaDeck

Versatile air conditioning for offices and administration buildings
Installation and operating instructions
The required room temperature is set on the room thermostat. If it
rises above the set value, the tangential fan starts up at the set speed
and the thermoelectric actuator valve opens the water-side valve.
In the event of a possible motor fault, the EC fan is disabled and a
potential-free fault message can be called up.
The clock thermostat 30456 permits the operation and temperature
control of 230 V electromechanical KaDeck units.
The room temperature is set by sensor-controlled functional keys.
Complete with 10-stage fan speed adjustment in manual and
automatic operating mode, including automatic summer/winter
changeover and a day or week program.
