1. INTRODUCTION
The BASIC microprocessor control is designed to manage CADB-D units in variable flow
mode. It is not possible to carry out controls of constant flow or constant pressure.
Equipment incorporating BASIC has an electrical cabinet where the equipment connections
can be accessed. In addition the equipment is fully wired inside, with the following compo-
nents:
• Differential pressure switches in both filters.
• Differential pressure switch in the fans.
• Electrical connections to the fans.
• Temperature probes for outside air (Te), return air (Tr), extracted air (Tx).
• Control (external, not wired).
2. INSTALLATION
Installation must be carried out by an experienced technician. The control is supplied not
wired to the unit; it must be connected to the equipment electrical cabinet.
2.1. PLACEMENT
For optimum operation, the control should be fitted to an indoor wall at about 1.5 metres
above floor level, away from sources of heat and not exposed to direct sunlight. Avoid
fitting the control near doors, where it could be hit and get damaged.
