START-UP

 

        

WARNING!

The installation and initial start-up of the appliance must be per-
formed by qualified personnel in compliance with the national reg-
ulations in force regarding installation.

CONTROL PANEL

The user interface has LCD display and 7 touch buttons. There are 
2 blue leds: ON (when the product is power supplied) and BOOST 
(when BOOST has been activated).

Estimated Energy Content 
(based on the set temperature)

Once the appliance is connected to the hydraulic and electric sys-
tems, the water heater must be filled with water from the domestic 
water supply network. In order to fill the water heater, it is neces-
sary to open the central tap of the domestic network supply and the 
nearest hot water tap, while making sure that all the air in the tank 
is gradually expelled. Visually inspect for possible water leaks from 
the flange and pipe fittings and gently tighten them, if necessary. 
The heat pump requires 5 minutes to become fully operational when 
starting it for the first time.

WARNING! Hot water at temperatures above 50 °C running from 
taps may immediately cause serious burns. Children, the disabled 
and the elderly run a greater risk in this regard. Therefore, it is 
advisable to use a thermostatic mixing valve connected to the ap-
pliance’s water outlet pipe, which is identified by a red collar.

WARNING!
If the water temperature is higher than the set temperature by 6°C, 
the display shows the icon 

INSTRUCTIONS FOR USE

Press the " 

 " button to turn the water heater on.

The display shows the set temperature and operation mode, while 
the  " 

 " symbol and/or " 

 " symbol indicate the operation 

of the heat pump and/or heating element respective.
Press the " 

 " button for 1 second to switch off the water heater. 

The protection against corrosion is ensured. The product ensures 
that water temperature inside the tank does not fall below 5°C.

SETTING THE TEMPERATURE

Press the “ 

+

 ” and “

 

-

 

” to set the desired hot water temperature (T 

SET POINT, the display will temporarily flash).
Press " 

SET 

" button to display the temperature of the water in the 

tank; it will be shown for 3 seconds.
In heat pump mode the min/max temperatures achievable are 
40°C/55°C, by default settings. This range can be extended (min/max 
40°C/62°C) in the installer menu. The maximum achievable tempera-
ture with the heating element is 75 °C. Changing the settings on the 
installer menu this valure can vary.

SHOWERS AVAILABLE " 

 "

When the display shows the icon, it means that at least one shower 
is available. The available showers depend on the availability of hot 
water. One shower is calculated as: 40 l at 40°C. 

MODE OF OPERATION

With the " 

MODE

 

" button you can modify the operating mode used 

by the water heater to reach the set temperature. The selected mode 
will be displayed on the line below the temperature.
If the heat pump is active, this symbol appears  " 

 "

If the electric heating element or integration is enabled, this symbol 
will appear " 

 ".

• GREEN
 

only the heat pump works, the priority is given to energy saving. 
The maximum achievable temperature depends on the value of 
the P7 parameter (40°C-62 °C) – (refer to Paragraph 7.7). Only for 
back-up or safety mode (errors, air temperature out of operating 
range, defrosting process in progress, antilegionnaire’s disease), 
the heating element may turn on and work.

• COMFORT
 

the water heater reaches set temperature with the rational use of 
the heat pump and, only if necessary, of the heating element. The 
priority is given to comfort.

• FAST
 

permanent boost mode, the water heater uses both heat pump 
and heating element to reach set temperature. The priority is giv-
en to heating time.

• I-MEMORY

  mode designed to optimize energy consumption and maximize 

comfort by monitoring the hot water needs of the user and the 
optimized use of the heat pump/heating element. The algorithm 
guarantees each daily need proposing the average of the profiles 
detected over the previous 4 weeks. In the first week of acquisi-
tion, the set point temperature entered by the user remain con-
stant; from the second week onwards, the algorithm will automat-
ically adjust the set point temperature to ensure daily needs. To 
reset the I-Memory profile use U9. (I-Memory mode is visible when 
U1: PROGRAM is ”OFF”)

•   HC-HP

  mode heating is performed within HC-HP signal detection in order 

to heat when low-tariff energy is available. The target temperature 
depend on the particular HC-HP mode selected:

- HC-HP:

 when signal EDF is detected, HP and HE can work (priori-

ty is given to HP). Antifreeze protection is guaranteed all day long.

-  HC-HP_40:

 when signal EDF is detected it works as HC-HP, oth-

erwise temperature is maintened at 40°C (HP only)

- HC-HP24h:

 when signal EDF is detected it works as HC-HP, 

otherwise set temperature is achieved with HP only (min/max 
40/62°C)
