17.3 “BUMP” FUNCTION
This feature is available only using ON-OFF compressors and if par. bMp=Y. When regulation
starts, the compressor will be activated and deactivated for a nub number of cycles and with a
duration respectively set in par. bon and boF. During the "BUMP" phase pressure/temperature
alarms are ignored.
17.4 COMPRESSOR CAPACITY LIMITATION IN CASE OF HIGH
CONDENSER PRESSURE/TEMPERATURE
If pressure/temperature measured from probe FPb>HAF, then the compressor capacity will be
able to be limited in the following way:
- By using par. HFL (if Digital or inverter-controlled compressor) for dHF interval of
time. After that, the compressor will be stopped if the alarm condition persists and if
HFC=YES
- Immediately stopped after dHF interval of time if ON-OFF compressor.
17.5 PRESSURE PROBE ERROR MANAGEMENT AT START-UP
At powering on, a pressure error probe will be signaled after the P1d delay expires. If pressure
error probe persists, the ON-OFF compressor will be activated following par. Con and CoF.
If regulation is stopped because of:
- Safety delays
- External alarms (from digital input)
- Pressure alarms
then any measured pressure value out of the probe range will not raise any additional alarm but
the display will show the last valid measured value.
