How energy efficiency is improved
Key directly on device for individual changeover between presence and absence
Areas of use
Individual unitary control and zone control (heating, cooling, heating/cooling) e.g. in air conditioning systems (2- or 4-pipe systems) in hotels and residential and business spaces.
Air-conditioning controller for 2- and 4-pipe systems (heating, cooling, heating/cooling)
Measurement of room temperature by either integrated or external temperature sensor
Saves energy costs by means of presence/absence key and rotary knob on front
Inputs for C/O signal, changeover between presence and absence, dew-point monitoring and setpoint shift
Choice of P or PI control with 2-point, pulse-pause, 3-point or outputs (0…10 V)
LED indicator
Servicing level with adjustable control parameters
Frost-protection facility
Electrical connection in baseplate
Electronics in attachable housing
