SUMMER MODE
During the summer months when there is no need for heating, sum­mer mode can be activated. This reduces the fan operation to 30% af­ter 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.

SYSTEM DESIGN
An air heating system combines air-based heating and balanced venti­lation 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.
SETTINGS
The temperature, fan speed and other parameters are set in consulta­tion with the installer/service personnel.
ELECTRICAL DATA

NORMAL MODE
The air heating unit automatically controls the fan speed to maintain the desired temperature.
FORCED MODE
The fan goes up to maximum flow. This function can be used to dis­tribute surplus heat through the house, for instance if a heating stove is used.
The unit operates in forced mode for 120 minutes, and then returns to NORMAL mode. If forced ventilation is required for only a short time, it can be terminated manually by pressing the arrow button and select ing NORMAL mode.
Example: If the NORMAL symbol flashes twice and the FORCED symbol flashes three times, the temperature is currently set at 23º C.
2. To change the temperature, press * to reduce it or # to increase it.
3. After setting the desired temperature, press ARROW to save and return to normal mode on the control panel.
