Honeywell PCR-100 Thermostat User Manual


 
7.1 Input parameters and input ranges:
Parameter on display Setting range
( or ) ( and or ) Preset
E00 Cold store temperature difference 1 to 20 K 2 K
E01 Min. permissible
cold store temp. –55 °C to E02 –55 °C
E02 Max. permissible
cold store temp. E01 to +50 °C +50 °C
E03 Delay time,
relay energizing 0 to 15 mins. 5 mins.
E04 Alarm temperature difference –50 K to +50 K 20 K
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 0 to 99 mins. 10 mins.
E06 Sensor calibration T1 –5 to +5 K 0 K
E07 Mode selection 1 = Cooling, 1
2 = Heating
E08 Time between 2 defrost cycles 1 to 24 hours 8 hours
(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.
