RDT 300: Electronic controller for ventilation and air- condi t i oning
How energy efficiency is improved
Top quality algorithm for generation of c/o signal for changeover between heating and cooling mode,
and therefore ensuring energy saving operation of the system.
Areas of application
Weather-compensated flow temperature control in 2- and 4-pipe systems for heating/cooling. Activation of intelligent unitary controllers.
Features
• Clearly-laid-out operating unit with large LCD display and generously proportioned keypad
• 6 controller models
• Plug-in memory for copying and documenting system parameters
• Fast commissioning thanks to preset parameters
• Room user panel with display available as accessory
• Weekly and annual switching program
• Automatic summertime/wintertime changeover
• Sealable sliding switch for selection of operating mode
Technical description
• Housing 144 x 96 mm made of flame-retardant, pure white thermoplastic (RAL 9010)
• 4 universal inputs and 2 analogue inputs
• 2 independent PI controllers
• 3 continuous outputs and 6 relay outputs
• Reset, sequencing and limiting functions, as well as alarm and time functions
• Suitable for fitting on walls, in panels and on top-hat rails
• Electrical connection in base with screw terminals for wires up to 2.5 mm²

Sauter Components
Operation
The RDT 300 controller has software modules with fixed configurations and captive standard parameters. The
software modules have definite links given by the control model. There are also modules for min./max. limitation.
All user parameters can be stored in the optional memory for documentation purposes or for 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 can be matched to the control task by selecting the appropriate control model, and the
inputs, outputs and additional functions can be configured.
Automatic
Control mode with setpoints as per weekly programme.
Manual
The current positioning signals are adopted on entering this mode. They can be set by hand between 0 and 100%.
Any necessary adjustments to the control parameters and to the time programme can be made in this mode.
