2.5.1.1. Alarms

This menu displays the notification of existing faults.

After failure elimination (see chapter 2.8), mes-

sages are deleted by selecting “Delete”. By click-

ing on „History“ can be viewed up to 50 registered

alarms.

2.5.1.2. Operation counters

This menu displays operation time of the fans, the

consumed energy of the heater and how much en-

ergy was recovered by the heat exchanger.

2.5.1.3. Efficiency status

Menu for the heat exchanger efficiency and energy

recovery monitoring in real time.

Also in this menu it is possible to start CF ex

changer calibration, if it was not performed during

first start of AHU. If calibration was successful and

“Calibrated” is shown – there is no need to start cali-

bration again. During calibration AHU will operate for

about 10 minutes on different ventilation intensities

while measuring internal pressure. Thus do not open

AHU doors, do not regulate duct system and do not

change any settings during CF calibration. If you wish

to stop calibration – turn off the unit from the control

panel.

2.5.1.4. Detailed information

All temperature sensor readings, functioning of sepa-

rate air handling unit elements and other detailed in-

formation is available in this menu.
