Honeywell PCR-100 Input parameters and input ranges, E00, E01, E02, E03, E04, E05, E06, E07, E08

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 (switch off cooling)

1 to 24 hours

8 hours

☛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.
