Input Parameters And Ranges - Honeywell PCR-100 Installation And Operating Instructions Manual

7.1 Input parameters and input ranges:
Parameter on display
( or )
E00 Cold store temperature difference
E01 Min. permissible
cold store temp.
E02 Max. permissible
cold store temp.
E03 Delay time,
relay energizing
E04 Alarm temperature difference
If the set temperature difference E04 is negative, an alarm is given
if it is too cold in the refrigerated area,
e.g. E04 = –10 K, cold store setpoint value = 18°C
alarm at –28 °C in refrigerated area.
If the set temperature difference E04 is positive, the alarm is given
if it is too warm in the refrigerated area,
e.g. E04 = +10 K, cold store setpoint value = –18°C
alarm at –8°C in refrigerated area.
Attention: any change of coldstore set point value changes also the
alarm temperature.
If E04 is set to 0, no alarm will be given.
E05 Alarm delay time
E06 Sensor calibration T1
E07 Mode selection
E08 Time between 2 defrost cycles
(switch off cooling)
Once the controller has been switched on, defrosting occurs
for the first time at the end of the first time interval.
After defrosting has been initiated manually, the next time
defrosting takes place is after a complete time interval has
elapsed.
