● Modulating heating coil(s).
● Modulating rotor speed
● Any external cooling unit and cooling recovery
Select Select one of the following:
● Supply air regulation - Typically used when the unit serves several rooms
with different loads (sunlight, people, machines). The temperature is regula-
ted by the built-in temperature sensor in the supply air spigot. If cooling
and/or heating coil(s) are fitted, temperature is regulated from the nearest
temperature sensor in the supply air duct.
● Room temperature control - Typically used when the unit serves several
rooms with similar loads. The temperature is regulated by the built-in temper-
ature sensor in the extract air spigot or via an external duct or room sensor
(accessory).
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 the room (CO
2
content in air)
2. Humidity compensation - Air humidity in the room
3. Airflow reduction - reducing the airflow in the event of falling supply air tem-
perature
4. Outdoor air compensation - reduces airflow in the event of falling outdoor
temperature falls
