Compressor (part 2)

The low pressure alarm can be managed

in a way to avoid a premature and unne-

cessary service intervention.

If the LP switch releases, the compressor

is stopped and restarted after the com

-

pressor pause has elapsed. The LP alarm

is inhibited during the winter start delay

(see page 70).

This way the controller tries to bypass

temporary LP alarms.

You can limit the number od compressor

restarts in "RESTARTS"

➐b within a time

space which you can adjust in the ﬁrst

line ➐.

If the maximum number of restarts is

reached, the LP alarm is released and

the compressor is deﬁnitely switched off.

Using the optional LP-sensor you can ad

-

just a threshold

➐a which marks the lower

limit for the permissible pressure range.

With a HP sensor (either part of G-valve

or separate option) high pressure alarms

can be equally managed for the same

reasons as LP alarms.

You can limit the number od compressor

restarts in "RESTARTS"

➑b within a time

space which you can adjust in the fourth

line ➑.

If the threshold ➑a of the HP is excee-

ded the adjusted number of times, the

HP alarm is released and the measure

which you have adjusted in HP mode

➒

is taken.
