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.

Operation with 2 compressors

In this case when Sd1>=Set+r0 the compressor with less hours of working is turned on 
first and after c6 delay the second compressor is turned on.
When Sd1<Set+r0/2 the second compressor is turned off and when Sd1<Set the first 
compressor is turned off.
If before turning off the first compressor Sd1>=Set+r0 the second compressor is 
turned on again.

HACCP

If this option is activated, the thermostat registers up to 5 alarms of the types High, Low, 
and blackout. These alarms can be seen in the menu Registry of Alarms (HAC). To 
access 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, the time and date (only models 
with real time clock) and elapsed   time of the alarm. For the disconnection alarm, the 
temperature, the time and date (only models with real time clock) 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      xxH   (Hours) 
will be shown, and pressing    again,   xxn (Minutes) will be displayed. When located 
over a temperature of alarm or time, pressing   +   during 2 seconds, both recorded 
data of the alarm (time and temperature value) are deleted. 
In the HAC menu, and pressing   +     keys during 2 seconds,   all the recorded data of 
alarms are deleted.

Defrosting Cycles

Intelligent Defrosting

By d13 parameter the time between defrost cycles can vary. The time is only counted if 
defrost probe is below the evaporator set d15.
Selecting d13=jup some of the defrosts will be skipped. After a defrost the following 
JdF defrosts will be ignored. JdF is initially 0. If a defrost ends before a time d16*d2 
then JdF is incremented, otherwise is decremented. Maximum value for JdF is 3. 
When JdF is 3 if the next defrost ends before a time d16*d2 then JdF is set to 1, 
otherwise is set to 0.
Selecting d13=Cic the defrosting cycle can vary.
If a defrost ends before a time d16*d2 then time between defrosts is incremented d17 
minutes, otherwise is decremented. The initial and minimum value for time between 
defrost is d8. The number of times that it is incremented it can be seen in JdF.

SLINK

This input allows to connect a programming key to read or to write the parameters.
It also admits a clock module so that the hour of the thermostat goes with a real 
time clock.
If the system is managed with a PC it can be connected it to the thermostat through 
this input with a communication module

The cycles of defrosting can be performed counting total time (d14= rt) or counting 
the time only when the compressor is connected (d14= ct).
If d14= rt, first defrosting will be always made at the hour d3 and the others with the 
cycle given by d8.
If d14= ct, defrosting will be always made with the cycle given by d8.
Manual defrosting do not modify the programmed.
