HL 722 Control Unit for Ventilation System Show data sheet (pdf file) Print page
Technical Description

The trainer HL 722 is required if the ventilation system HL 720 is to be used for experiments with room temperature control.

  The trainer is connected between the ventilation system and an external source of hot water using quick-release couplings. With this arrangement it is possible to demonstrate room temperature control in ventilation systems.

  Only original parts were used for the trainer.
