1 flexotron 300 RDT 0: Electronic controller f ventilation and air-conditioning How energy efficiency is improved Highest level of flexibility as regards adaptation of the controller to the particular system and therefe a guarantee of extremely efficient operation. Areas of application Moniting and control of temperature, humidity, pressure and flow rate in ventilation and airconditioning applications. Features Clearly laid out operating unit with large LCD display and generously proptioned kead 3 controller models Plug-in memy f copying and documenting system parameters Fast commissioning thanks to preset parameters Sealable sliding switch f selection of operating mode Technical description Housing x 9 mm made of flame-retardant, pure white thermoplastic (RAL 90) universal inputs and digital input P,, cascade and differential control 3 continuous outputs and relay outputs (-point 3-point) Reset, sequencing and limiting functions Suitable f fitting on walls, in panels and on top-hat rails Electrical connection in base with screw terminals f wires up to. mm² Te ) Range C Control modes Voltage Weight kg RDT 0 F P,, pt, 3pt 30 V~ 0, RDT 0 F P,, pt, 3pt V~ 0, Models Structure of controller output continuous Sequence contin.-contin Sequence contin.-pt output pt fixed-value controller: 0 30 with command 3 3 fixed-value controller: with common actual value with y = min/max selection controller with command 3 with common command common actual value; once with command common acttual value; common command cascade controller: 3 with command 33 differential controller: with command 3 output (3pt) Ranges (depends Temperature Percentage Rel. humidity Abs. humidity Enthalpy no units on transmitter) C K % %rh g/kg kj/kg Setpoint X s C P-band 0,...0 K 0, ,...0 0,...0 0, universal inputs ) binary input ) Threshold V Temperature Ni00 (DIN 30) Voltage 0()...

When selecting the control model, the software modules are linked to (f instance) a cascade controller with sequence output and shift. There are also modules f min./max. limitation, selection and external setpoint. All user parameters can be sted in the optional memy f documentation purposes f copying when installations are similar. All parameters are captive. The sliding switch (Hand/Automatic/Service) controls the operating modes. Service In this mode, the controller is matched to the control task by selecting the appropriate control model, and the inputs and outputs and the additional functions are configured. Automatic Control mode with setpoint Xs internal external; Xs internal only. On entering this mode, the prevailing positioning signals are adopted. They can be set manually between 0 and 0%. Any adjustments to the control parameters are made in the Hand mode.
