d1 – Power supply ON/OFF 1 (Automatic Operation when Power Supply is ON)
This function stores the unit settings in the event of a power cut. The unit is restarted when the power is re-established.
?
C A U T I O N
When this function is used without anyone controlling the unit, set the system monitoring mode to avoid risks.
?
N O T E
In the event of an electrical fault, the unit starts and stops according to the on/off setting of the power supply. If the fault occurs during a
stoppage enabled through the remote control, the unit will restart automatically once the power supply is reconnected.
d2 – Not available
d3 – Power supply ON/OFF 2 (Restarting Function After Power Failure)
This function is used to restart the unit after a power cut taking more than 2 seconds. The standard unit starts
automatically under the same operating conditions, such as the operating mode, etc. in the case of an electrical fault
lasting for a maximum of 2 seconds.
The compressor unit restarts after 3 minutes plus the maximum 2 seconds of the fault.
?
C A U T I O N
When this function is used without anyone controlling the unit, set the system monitoring mode to avoid risks.
d4 – Prevention of drop of discharge temperature in cooling
This function is avoiding getting a too low air outlet temperature from indoor units in cooling operation. Remote Control
Switch is controlling the air outlet temperature and adjusting the Thermo-ON/OFF status accordingly.
When ambient temperature > setting temperature:
-
If air outlet temperature ≤ 11 ºC for 3 minutes, the system is switched to Thermo-OFF.
-
In this status, if air outlet temperature ≥ 13 ºC, the system is switched back to Thermo-ON.
This optional function is only available for the following indoor units models: RPI-(4.0-6.0)FSRE
For the following indoor units: RCD, RPK, RCI, RCIM, RPF(I), RPI-(0.4-3.0)FNS5E, RPI-(8~20)FSN3(P)E, this function is
not used.
d5 – Prevention of decrease of heating discharge air temperature
This function prevents a drop in the air temperature by decreasing the fan speed, apart from the settings on the remote
control.
d6 – Room temperature control for energy saving
This function saves energy when the outdoor temperature is lower than the air conditioning load.
The indoor unit is set to cooling Thermo-OFF when: T
out
(outside ambient temperature - out of the building) < T
in
d7 – Only for Econofresh: OA Damper minimum opening
This function is setting the minimum opening angle of the damper for fresh-air intake.
E1 – KPI ventilation mode
This function is used to set the unit ventilation mode with energy / heat recovery
This function is useful to set the heat exchanger ventilation mode. The setting condition and ventilation mode are shown
below:
