If the temperature/pressure decreases under the set rC06-rC07 the heat recovery operation is re-enabled.
To avoid long period in wich the heat recovery function is disabled and if the condenser
temperature/pressure within the range rC06-rC07, the units starts counting the delay set in rC08. After this
delay if the decreasing temperature is still within the rC06-rC07 range, the recovery cycle is forced on again.

o
AL05=0
o
0<AL05<16:
o
AL05=16
Compressor overload alarm is managed in a special way:
- when the number of the alarms per hour is < AL20, the alarm is a manual reset
- when the number of the event is = AL20, the alarm is manual reset and a password is requested. In
this case the alarm is stored and visible in COtr menu.
