Programme Selection; Fast Button - Ariston Heat pump water heater User Manual

From this moment on, the appliance operates in the heat pump mode which will turn off once the water reaches 55°C;
once this occurs, the heating element activates until the water reaches the desired temperature, which can be set to
between 55°C to 65°C.
During the programmed operating mode as signalled by the P1 (9) and P2 (8) LEDs turned on (both or just one turned
on), it is not possible to modify the temperature setting directly, as it must be linked to a time setting specified by the
user. When attempting to modify the temperature by pressing the SET (3) knob, "Pr" will appear on the DISPLAY (10)
for 3 seconds, to remind the user that a programme must be selected, according to the procedure described in the
following paragraph.

4.6 Programme selection

Switching from manual to programmed operating mode (Fig. 8) is done by repeatedly pressing the MODE (2) button;
the respective MANUAL, P1, P2, P1+P2 LEDs (7-8-9) turn on, where P1 and P2 indicate the two available programmes
that can be selected individually or together during the course of the day.
Each programme allows for associating a desired temperature to a given time of the day; the appliance then activates
the heating phase to enable the water in the tank to reach the desired temperature at the pre-set time (hereinafter
simply referred to as SHOWER TIME).
The programmes can be configured in the following way (Fig. 8):
- Press the MODE (2) button repeatedly to select either programme P1 or P2 or both; the corresponding
LEDs (8 and 9) will flash to signal the selection.
- The DISPLAY (10) starts flashing and the previously set SHOWER TIME appears.
- Turn the SET (3) knob within 5 seconds towards the right (+) or left (-) until the desired SHOWER TIME (30-
minute intervals) setting appears on the DISPLAY.
- Confirm the setting by pressing the SET knob (3).
- The DISPLAY (10) starts flashing and the previously set temperature appears.
- Turn the SET (3) knob within 5 seconds towards the right (+) or left (-) until the DISPLAY visualises the
desired temperature, which can be set to values of up to 65°C.
- Confirm the setting by pressing the SET (3) knob; the DISPLAY (10) will visualise the current temperature
again.

4.7 FAST button

Should the user require hot water in the shortest possible time, the heating time can be drastically reduced by jointly
activating the heat pump and the heating element; this entails an increased power consumption.
This mode can be selected using the appropriate FAST (5) button as follows:
- Press the FAST (5) button; the orange light turns on while the green light of the previously activated ECO
HP (4) button turns off.
- Turn the SET (3) knob towards the right (+) or left (-) until the DISPLAY (10) visualises the desired temperature,
which can be set to values of up to 65°C.
- Confirm the setting by pressing the SET knob (3).
The use of the FAST button is intended for a single cycle only; this mode automatically deactivates when the set
temperature is reached after which the water heater automatically operates in the heat pump mode according to the
previously set temperature, up to a maximum of 55°C.
