Fireplace function
The fireplace function is designed to create overpressure in the house, so
that the fireplace can be lit without problems. The overpressure is created
by reducing the extraction and maintaining the supply at fan step 3.
The function is activated/deactivated by pressing UP for 5 seconds, then
FP07 is shown in the INFO LINE = fireplace mode for 7 min. It now counts
down (FP07…FP01) till 7 minutes have passed, and then the unit returns to
the previous operation mode.
Please notice!
The fireplace function cannot be activated if outdoor temperature (T1) is
lower than -13°C. This can be solved by adding a preheater (accessory).
Bypass-
cooling
Only available if mechanical bypass damper is mounted
AUTOMATIC BYPASS-COOLING
The built-in AUTOMATIC BYPASS-COOLING mode is used during summer
time when the outdoor temperature is higher than 15°C, as long as it is
lover than inside air temperature. This means it is not necessary to activate
the MANUAL BYPASS-COOLING during this period.
The setpoints for AUTOMATIC BYPASS-COOLING can be adjusted if
needed in the INSTALLER MENU.
MANUAL BYPASS-COOLING (BYP6)
The MANUAL BYPASS-COOLING mode can be useful if cooling is needed in
the spring or autumn (when the outdoor temperature is below 15°C) in-
stead of using the heat recovery function.
MANUAL BYPASS-COOLING is activated by pressing DOWN for 5 sec. and
the display will shows BYP6 and the unit will be cooling for 6 hours. After
the 6 hours the unit returns to heat exchanger mode with AUTOMATIC BY-
PASS-COOLING.
Please notice!
Only when the conditions for BYPASS-COOLING mode are actually present
the display will show parallel air channels (no heat recovery) and the
BYPASS-COOLING damper opens.
