5.1.8 Enthalpy control

Calculating the enthalpy means to calculate the energy content of the air, taking into consideration
both the temperature and the air humidity. The value is given in energy per kilogram air (kJ/kg). If
enthalpy control is configured, the enthalpy is calculated both indoors and outdoors. If the enthalpy
is higher outdoors than indoors, the recirculation damper will be overridden to increase the
recirculation. The function is not active when using free cooling, in this case outdoor air is used for
cooling the room instead. For the enthalpy calculation to be made, four sensors are required:

5.1.9 Heat exchanger efficiency monitoring

General

The function calculates the heat exchanger temperature efficiency in percent when the output signal
to the exchanger is higher than 5 % and the outdoor temperature is lower than 10°C.

When the control signal is lower than 5 % or the outdoor temperature is higher than 10°C the
display will show 0 %.

The heat exchanger efficiency is calculated using the following formula:

Efficiency = (Extractairtemp – Exhaustairtemp) /
(Extractairtemp – Outdoortemp) * 100

Alarm

An alarm is activated if the efficiency falls below the set alarm level (50 %).
