flexotron 300
RDT 300: Electronic controller for ventilation and air-conditioning
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. Activa-
tion of intelligent unitary controllers.
