7. COMMISSIONING
All the RHE units are subjected to a DC check and a functional test before they are delivered.
Factory parameter settings of the units :
Ventilation mode = CAV mode (description in subsection « Constant airflow operation (CAV) »).
High speed = Unit’s max airflow, Low speed = Max airflow / 2.
Fan type : determined according to the airflow coefficient K specific to the fans (description in
subsection “External input for fire mode”).
Heating mode = constant supply T° (description in subsection « Constant airflow operation (CAV) »).
Heater type (description in subsection “Constant supply air temperature maintenance
”
) : according
to the requested option (by default the electrical resistance is selected).
Factory check of the units :
Electrical conformity tests : Continuity of the ground / Insulation of the electrically powered parts.
Check of the reading of the temperature probes (supply T°, extraction T°, outdoor T°, antifreeze T°
according to option).
Check of the supply fan only (Check of the corresponding airflow sensor).
Check of the extraction fan only (Check of the corresponding airflow sensor).
Check of the heat exchanger (start/stop).
The commissioning and parameter setting of the controller must be performed by a qualified person
respecting the safety instructions described in subsection “Safety instructions”.
Only after the installation is completed can the electric, aerolic and hydraulic connection operations be
performed.
Prior to commissioning and parameter setting, provide yourself with the necessary data, airflows,
pressures, temperatures, desired operation mode and schematic diagrams of the installation.
Make sure that the device does not contain any foreign objects.
Make sure that all the components are attached in their original locations.
Check manually that the fans do not rub or are not blocked.
Make sure that the rotating heat exchanger is not blocked.
Make sure that all the outdoor electrical devices are connected.
Check the tightness of the electric connections / earthing connection.
Check the voltages, currents, gauges of the thermal protective devices.
Check the rotating direction of the fans – airflow directions.
Check the airflow rates.
Make sure that the filters are not clogged – clean them or replace them, if necessary.
Enter the control parameters; simulate the operation of the batteries / alarms / safeties.
