19.1. COMMISSIONING
The commissioning/starting up of the unit is based on two menus: Fan settings and Fan menu:
Ventilation modes
The first step is to select the ventilation mode:
• CAV: Standard operation. Operation at constant flow.
• VAV: Variable flow operation. Manually or according to an external 0-10V sensor (accessory).
• COP: Operation at constant pressure by means of an external accesory (TDP-S).
After a change in the selected operation mode, the fans stop and re-start in the new selected mode.
In units with electrical pre/post heating, if the operation mode is changed while the fans are running, the unit will stop
sequentially: first switching off the electrical heater and after 2 minutes, switching off the fans. Finally, the unit will re-
start at the selected working mode.
