(i.e. the utility managed by the fourth output and/or the
utility managed by the fifth output is the alarm output) and
parameter u4 is set at 1, pressing the key will also cause
the deactivation of the output.
If parameter u9 is set at 0, the buzzer will not be activated.
4 MULTIDECK
4.1 Preliminary notes
If parameter P4 is set at 3, the temperature associated to
the regulation will mainly depend on the temperature detected by the inlet air probe and that detected by the air
outlet probe, herein called CPT temperature (Calculated
Product Temperature).
The formula for the calculation of the CPT temperature is:
CPT temperature= {[(value established with parameter P7)
x (temperature detected by the inlet air probe)] + [(100 value established with parameter P7) x (temperature detected by the outlet air probe)] : 100}.
5 ENERGY SAVING
5.1 Preliminary notes
Once the time you have set with parameter i10 has passed,
without activations of the door micro switch input (after the
cabinet temperature or CPT temperature has reached the
work set-point) the “energy saving” function is activated
(until the input is activated again).
During the “energy saving” function, the work set point is
increased by the temperature established with parameter
r4.
In case of analogue management, the evaporator fan is
switched on (if required) at the speed established with parameter F21; in case of digital management, the evaporator
fan is switched on in cyclic mode (parameter F13 establishes
the duration of fan switch off and parameter F14 that of
switch on.
It is also possible to activate the “energy saving” function in
remote mode through the digital inputs (with effect only on
the compressor), through parameters H01... H14 it is finally
possible to activate the “energy saving” function in real time
(EVRS235 model only).
6 “HACCP” FUNCTION
6.1 Preliminary notes
The device can memorise the following HACCP alarms:
- minimum temperature alarm (code “AL”)
- maximum temperature alarm (code “AH”)
- door micro switch input alarm (code “id”)
- power supply cut-off alarm (“PF code”; in EVRS235
model only).
EVRS225 can memorise up to 3 alarms (one per type);
EVRS235 can memorise up to 9 alarms, after which the
oldest alarm is overwritten.
The device supplies the following information for every alarm:
- the critical value
- the date and time at which the alarm occurs (EVRS235
model only)
- the duration of the alarm (from 1 min to 99 hours and
59 min, partial if the alarm is in progress).
Code Critical value
AL the minimum cabinet temperature or the minimum
CPT temperature during the alarm
AH the maximum cabinet temperature or the
maximum CPT temperature during the alarm
iD the maximum cabinet temperature or maximum
CPT temperature during any alarm of this type;
see also parameter i4
PF the cabinet temperature or the CPT temperature
when power supply is restored; see also parameters A10 and A12
EVRS225 updates the information regarding the the alarms
provided the critical value of the new alarm is more critical
than that stored or provided the information has already
been displayed.
The device stored the minimum temperature alarm on condition that the temperature associated to the alarm is that of
the cabinet or CPT (parameter A0 = 0).
if the device is switched off, no alarms will be stored.
The “HACCP” LED provides information regarding the storage status of the alarms; see paragraph 10.1.
