About the unit

1.3.1 Application and operation of the air curtain

The air curtain is designed to separate indoor and outdoor climates. The unit draws air from the room and discharges it, either heated or not, across the width of the doorway. The air curtain removes the undesired effects of an open door by either reducing the exchange of indoor and outside air, by heating the entering air, or a combination of the two.

Mounting methods

The free-hanging model is designed for free, visible installation above the door.

2.7.1 Control panel details

Positioning

• You may fix the control panel either to the wall or to a standard junction box.

Cabling n Note:

Take the following into account, otherwise faults may occur:

- The control cable between the control panel and the

(first) connected unit may not be longer than 30 m

(98 ft).

- Keep control cables away from electromagnetic fields and interference sources such as high-voltage cables and fluorescent-light starters.

- Lay control cables out straight or roll them bifilarly by folding cables in half before rolling them. This significantly reduces inductance.

- Do not remove the dummy plug, unless otherwise stated.

n Note:

Use Biddle control cables only (Type RJ4). Standard modular telephone cable is NOT suitable.

Multiple units operated from one single control panel

• A maximum of 8 units can be connected to a single control panel. n Note:

The RSR receiver module counts as one unit.

• Units are daisy chained using Biddle control cables and

Connectors E and G .

• The total length of the control cables must not exceed 30 m (98 ft). If the distance is too great, an additional control panel must be connected.

• Configure any one unit as a master. The sequence of the connected units is not important.

Units with two control circuit boards

Only the following types: DF S-250-E, M-250-E.

These units have two control circuit boards that each control a part of the unit. The control circuit board on the connection side has been configured as master on delivery.

You can connect one or more of these units to a single control panel in combination with other units. The following applies in this regard:

• A unit with two control circuit boards counts as two units.

• A unit with two control circuit boards is always the master unit. Units with a single control circuit board must be configured as normal units.

• If several units have two control circuit boards, then one of these units is configured as the master unit. All control circuit boards in all other units must be configured as normal units.

• The control panel and the external control components must always be connected to the master unit.

2.7.2 Control panel settings
