At this point the current configuration of the unit will be displayed for a few moments as indicated below:
LED A (red) on: the unit is configured as a heat pump;
LED B (green) on: the unit is setup for the lower part of the wall (factory default);
LED C (yellow) on: the unit is setup for the upper part of the wall;
LED D (green) on: reset settings function after an active black-out (factory setting).
At this point all of the LEDs on the console will start flashing simultaneously for 10 seconds.
During this time the configuration of the unit can be changed by pressing the reset key (H) until the settings
match your specific application.
Configuration of the control board for installation to the upper part of the wall sets an automatic
correction of the detected room temperature detected of 5.5º.
At this point the self-diagnostic function activates the appliance in heating mode (if fitted with the heat pump
function) for approx. 2 minutes and then in cooling mode for another 2 minutes. it is possible to terminate
the function prematurely simply by switching the appliance off using the remote control.
Should the unit stop and signal an error, determine which LEDs are flashing then use the chart below to
determine the cause:
DESCRIPTION
overtemperature of internal exchanger (Hti)
overtemperature of external exchanger (Hte)
external temperature probe fault (short circuit) (tfS7)
external temperature probe fault (open circuit) (tfS8)
internal fan malfunction (SV)
Insufficient exchanger temperature (CF/RL)
maximum level of condensate water (of)
invalid eeprom parameters (CKS)
room temperature probe fault (short circuit) (tfS1)
room temperature probe fault (open circuit) (tfS2)
internal exchanger temperature probe fault (short circuit)
(tfS3)
internal exchanger temperature probe fault (open circuit)
(tfS4)
external exchanger temperature probe fault (short circuit)
(tfS5)
external exchanger temperature probe fault (open
circuit) (tfS6)
: flashing
WARNINGS DISPLAYED DURING NORMAL OPERATION SHOULD NOT BE INTERPRETED AS ERRORS.
LED A: Indicates the filter may need cleaning.
After cleaning or replacing the filter the LED must be switched off manually as indicated in section 2.6.1
leD B steady light: indicates high battery temperature signal.
LED A + LED C flashing: Indicates continuous pump operation.
