Compensation
Compensation Each form of regulation provides different options for set point compensation. See
the next sections.
General Compensation of the airflow and temperature is carried out by a sensor sending
signals to the control system, which then reduces or increases airflow and temper-
ature if required. Airflow and temperature are always compensated, no matter which
indoor air quality level the unit is set to.
Menu 3.1.2 - Air compensation
Airflow Compensa-
tion Airflow compensation can be carried out on the basis of the following:
1. CO
2
compensation - Air quality in room (CO
2
content of air)
2. Humidity compensation - Air humidity in room
3. Airflow reduction - reduces airflow in case of falling supply air temperature
4. Outdoor compensation of airflow - reduces the airflow in case of falling out-
door temperature
NB
●
All compensation options can be connected and active at the same time, and
may influence the control airflow
Autostart with timer
operation If the weekly schedule is at OFF and either the CO
2
or the humidity level exceeds
the starting limit for CO
2
or humidity compensation, the VEX will automatically start
up using the settings from indoor climate level "Economy".
Menu 3.1.2.1 - CO
2
compensation
Requirements A CO
2
sensor (CO2B, MIO-CO2, BMS) must be mounted to allow selection of
CO
2
compensation of the airflow. Connection of the sensor is described in the ad-
ditional instructions accompanying the sensor.
Function When the control system is operating, this function can be used to increase the
airflow in the event of increasing CO
2
levels.
Selection of CO
2
compensation
