RECOVERY
Recovery mode
- selecting the operation mode for the recirculation
chamber
•
MECH
– Maximum Energy Changeover – control from the PID
controller, recirculation plays the role of the
fi
rst heating / cooling
section in order to take full advantage of energy recovery, the scope
of possible changes concerning recirculation is de

ned by

setting of minimum fresh air.

xed manual recirculation settings
•
Univ.AI
– control from the universal analog input; the range of
possible changes is limited by the setting of minimum fresh air
Recovery rate
– indicates current recovery capacity, gives a link
to output detail screen (password protected link – see Advanced
Manual)
0% – no recovery, 100% – full recovery
Note!
The controller signal can differ from the actual recovery rate
due to protective functions that could affect it.
Frost prot. rate
– indicates the rate of frost protection, that is
subtracted from controller signal in order to protect the recovery unit
from freezing
Note
!
Frost protection can be managed in two stages - first step
can be reduction of supply fan speed, second step is reducing the
recovery rate
Glycol pump
– indicates current state of the pump, gives a link to
pump detail screen (see Advanced manual)
Status
- combined information for communication problems and for
motor alarms
OK
- no malfunctions
Comm
- communication to the frequency converter not stable or lost
Alarm
- communication OK, but frequency converter reported an
error, e.g. overload
CO2 value
- value of CO2 concentration
