RDT 100: Electronic controller for ventilation and air-conditioning
For universal, autonomous use in ventilation and air-conditioning systems or similar; with
measurement, control and time functions for controlling temperature, humidity, pressure and flow.
DDC compact controller with PI, two- or three-point control and command, sequence and limitation
functions. Thirty-five configurations of control models available. All parameters are pre-set and enable
commissioning to be executed quickly. Plug-in memory available as an option, for documenting and for
copying the setting parameters.
Front plate with LCD panel, keys and sealable, 3-position sliding switch (manual, automatic,
service); snap-shut flap for covering the service keys and for safeguarding the abridged operating
instructions. Housing 144 ×96 mm (DIN 43700) of flame-resistant, pure-white thermoplastic
(RAL 9010); for mounting onto walls, into control panels or onto top-hat rails as per EN 50022. PI
