6.6.3.5. Pressure switch connection

All CAD-COMPACT range of heat recovery units have differencial pressure switches to perform the control of 

polluted filters. The pressure switches are located inside the equipment and wired to the electrical cabinet. If you 

want to obtain specific information on the status of the filters through (light or sound indication), it is possible to 

carry out an electrical operation by passing the power line through the filter contact.
