Display Messages
In normal operation the probe temperature selected by P5 will be displayed.
The following messages can also appear :
- Err Memory reading error.
- ErP1, ErP2, ErP3 Probe1 , 2 or 3 error
- Eri Internal parameter error. In this case, enter the standard configuration,
as it is indicated in “To record a standard configuration”.
- ALH High temperature alarm.
- ALL Low temperature alarm.
- ALE External alarm.
- AEH High temperature and external alarm.
- AEL Low temperature and external alarm.
- ooo Open probe.
- - - - Short-circuited probe.
- DON Defrosting activated.
- DOF Defrosting de-activated or cannot be done.
- CON Continuous cold cycle activated.
- COF Continuous cold cycle de-activated or cannot be done.
- -d- Thermostat on defrosting.
To view the probe not chosen by P5, press SET+UP
The display blinks when there is an error recording a parameter in memory or
when awaiting confirmation of a value.
Operation in Error Case
If the ambient probe fails, the thermostat will connect the compressor
according to parameters c2 and c3, being able to perform defrosting and
continuous cold cycles.
If the memory fails the thermostat will connect the compressor ON for 5
minutes and OFF for 5 minutes, not being able to perform defrosting or
continuous cold cycles.
Buzzer Operation
If there is a memory error, probe error, temperature alarm (high or low),
external alarm or door open alarm, the internal buzzer sounds.
The buzzer can be muted pressing any key.
Two Compressors Operation
In this case, when the thermostat demands cold (Sd1 >= Set+r0) the first
compressor to be connected is the compressor with less running hours, and
after c6 seconds, the second compressor is also connected. When the
thermostat begins to cool, and Sd1<Set+r0/2 is reached, the second
compressor stops, and the first one continues. The second will be stopped
when Sd1<Set. Nevertheless, if before stopping the first compressor, Sd1 >=
Set+r0, the second compressor starts running again.
HACCP
If this option is activated, the thermostat registers up to 5 alarms of the types
Hight, Low, and blackout. These alarms can be seen in the menu Registry of
Alarms (HAC). To acced to this menu, proceed as for the parameters menu.
The first value that appears is the number of registered alarms. Afterwards,
for each alarm (if it has existed), the value of the temperature and the time of
the alarm. For the disconnection alarm, the temperature when returning the
connection is registered, as well as the time until the correct values are
reached. (Probe<Set+A1-A0)
When the elapsed time is showed it will appear xxd (days).Pressing UP xxH
(Hours) will be shown, and pressing UP again, xxn (Minutes) will be
displayed. When located over a temperature of alarm or time, pressing
UP+DOWN during 2 seconds, both recorded data of the alarm (time and
temperature value) are deleted.
In the Ald menu, and pressing UP+DOWN keys during 2 seconds, all the
recorded data of alarms are deleted.

Manual Defrost.
Pressing UP key for 8 seconds defrost is activated. Repeating the
operation is deactivated.
Continuous cold cycle.
Pressing DOWN key for 8 seconds a continuous cold cycle begins.
Repeating the operation the cycle finalizes.
Setting keyboard code to zero
The keyboard code can be programmed to zero by turning off the
controller, and turning it on again, while the key SET is pressed.
Alarm validation
An active alarm can be validated (the alarm output will be turned off)
pressing the SET and DOWN keys simultaneously.
Led Indications
Out: It indicates Compressor connected. It blinks when a
continuous cold cycle has to be initiated and has to wait until the
minimum compressor stoppage time is over.
Def: It indicates defrosting is activated.
Fan: It indicates ventilator is connected.
Alarm: It indicates an error or alarm. It blinks when the alarm is
validated by the user
ON OFF Thermostat
Pressing the keys SET+DOWN for 8 seconds the thermostat will
turn-on or turn-off
If we have a relay setup as light, pressing keys UP+DOWN for 3
seconds the thermostat will turn-on or turn-off the light
The cycles of defrosting can be performed counting total time (d14=
rt) or counting the time only when the compressor is connected
(d14= ct). When (d14= rt) and (d8 24.0 ) First defrosting of day is
made at the hour d3 And the others with the cycle given by d8.
When (d14= ct) or (d8 24.0 ) the cycle is only performed by d8 .
Hour/Minutes Parameters H-M
It is a way to show hours and minutes in 3 digits
The two first digits are the hours and the third the tens of minutes.
E.g. 2.4 2 hours 40 minutes
8.0 8 hours 0 minutes
10.3 10 hours 30 minutes

In this input we can connect a programming key to read or to write the
parameters. We can also connect a clock module so that the hour of
the thermostat goes with a realtime clock. If we manage the system
with a PC we can connect it to the thermostat through this input with a
communication module.
