6.6.4.1. Manual VAV control (variable airfl ow)
It is possible to control in VAV mode manually with an external potentiometer.
Manual control by external potentiometer REB-ECOWATT (accessory). Valid for CADB/T-HE
04 to 27 models.
IMPORTANT: RISK OF FIRE
The manual speed control, must not be carried out in DI-versions (with electrical
resistances).
The direct stop of the fans without a temporized stop would cause a high temperatu-
re rise of the resistances, and the consequent risk of fi re inside the unit.
