Cooling

operation

The Flexibox controller continuously monitors the inside as well as the outside air te

perature, and select appropriate operation mode accordingly.

Mode

Description

External heating If the inside temperature is lower than the heat setpoint (“Heater

SetPt.”) parameter, any external heater connected to the Flexibox,

will be activated.

Free cooling If the inside temperature is higher than setpoint, the internal fan of

the Flexibox starts up slowly, and increases/decreases speed, to

maintain the setpoint temperature.

Free cooling operation is dependent on a lower outside than inside

temperature.

In Free cooling operation, the damper will open, to emit warm air to

the outside surroundings.

External

AC cooling

If the inside temperature is higher than setpoint, and outside air is

higher than inside, minus the temperature delta of 3° by default, the

Flexibox will change to external AC mode, if connected.

In this operation mode, the damper is closed.

Alarms The controller can issue various alarms, on any of the two alarm

connections. This can be set up in the configuration. See more at

page 26

By default the alarms is setup to:

•Alarm output 1 is operation error alarms, that needs immedi-

ate attention

•Alarm output 2 is activated by the filter surveillance. This

doesn’t need immediate action, and could be handle as an

warning
