Section IV - Operating Procedures
Energy Management Application
Selection
For correct energy management operation
it is important to select the correct mode
of operation for the application.
For applications where the compressor,
receiver and the dryer are in the same
location, linking the controller energy
management into the compressor pressure
limit switch, an effective method of energy
saving is offered.

For applications where the compressor
is a continual operating type or the dryer
is point of use or is remote from the
receiver, a dewpoint dependant method of
switching should be employed.
This links the operation of the energy
management to the outlet dewpoint from
the dryer.
