2.9 TOTAL RECOVERY MONITOR

WARNING: this mask is available on units with total recovery.
This mask is used to display the status of the total recovery:
Total Recovery
Inlet water:
Out Total Rec.:
O unit
Total require:
— Display of the water temperature value of the total recovery input probe;
— Display of the water temperature value of the total recovery output probe;
Total recovery status:
— flow switch open (water is not circulating in the hydraulic circuit of the recovery
system and therefore it is disabled);
— enabled (water is circulating in the hydraulic circuit of the recovery system and
therefore it is enabled);
— general off (the whole unit is in stand-by), off from the display (general disa-
bling of the unit from the pGD1 button);

2.10 PEC PRESSURE CONTROL MONITOR

This mask is used to display the result of the control on the machine pressure delta,
controlled by the PEC card:
Circuit 1
PEC
Pressure delta control
in progress...
:
If the result of the pressure delta control is greater than 15 bar (and the 4-way must
switch), the valves must be controlled without the activation of the compressors to
reduce the pressure delta; Alarms (warnings) are not generated in this situation).
If the control is less than 3 bar (hot/cold operation or a 4-way must switch), the
compressors are started without the valve control in order to create the pressure
delta; after 300s in this situation an alarm is generated with a machine block.
