Thermostatic control

The water heated units of the DoorFlow come as a standard with an air side speed

controller and can be extended with a water side room temperature controller.

Electrically heated units come as a standard with a room temperature controller.

1. Air side control

The air side control allows the user to regulate the speed of the air curtain using the

controller. Three fan speeds are available: low - medium - high.

2. Water side room temperature control

Electrically heated units come standard with room temperature control. With hot water

heated units, the air side control can be extended with waterside control (3-way

valve). By means of the water control, it is possible to set the room temperature

manually or automatically via the control panel.

Manual setting

The heating can be switched manually to 100 or 50% of the capacity. Besides, it is

possible to switch off the heating (ambient) to make climate separation possible

during warm periods or in cooled spaces (see page 5).

Automatic setting

If the air curtain is controlled automatically, the air curtain itself reads the room

temperature and automatically selects the correct heating level to ensure and maintain

the preset room temperature level. The desired room temperature can be selected

by means of the control panel. The LEDs represent the temperature setting of 18 ºC

to 25 ºC. The heating can be switched off which is shown by the bottom LED. For

instance, if 22 ºC is set, the air curtain automatically selects the correct capacity to

ensure this room temperature is maintained.

Control of more units

Multiple units (max. 8) can be controlled by one control panel.

More control options

Also a timer, door contact switch and BMS can be connected to the electronic control.
