SYSTEM DESIGN

An air heating system combines air-based heating and balanced venti-
lation with heat recovery. 
The heat recovery units can be installed in a kitchen, store room, scul-
lery or attic.
An air heating system uses the same ducts for ventilation and heating.

CONTROL

The control unit automatically controls the ACJB unit’s fan and  
water or electric heater to maintain the desired temperature.

THE UNIT’S MAIN COMPONENTS

1. Coarse filter (G3) ISO Coarse

2. Fine filter (M5) ISO Coarse 85%

3. Secondary air fan

4. Control unit

5. Postheater (water/electrical)

6. Casing

SUMMER MODE

During the summer months when there is no need for heating, sum-
mer mode can be activated. This reduces the fan operation to 30% af-
ter a set time delay (normally 24 hours). Summer mode is indicated by 
a LED on the control panel. 
Summer mode is automatically deactivated when there is a need for 
heating. 

SETTINGS

The temperature, fan speed and other parameters are set in consulta-
tion with the installer/service personnel.
