Operating Modes
The Eco system is programmed to work in 3 running modes, ECO, AUTO and BOOST, which are
summarized in this table:
Note that the electrical heater is sometimes referred to as “Immersion heater”, or
“Resistance” in the Eco system
.
ECO Operating Mode
In ECO operating mode, the equipment runs only as a Thermodynamic System to heat the
water in the hot water cylinder maximising savings for the user.
If required, the electrical heater (immersion heater) may be activated by manually pressing the
key (E-HEATER). The system will automatically change operating mode to BOOST and indicates
the reason of its activation. If you manually switch off the E heater, the equipment will revert
to ECO mode.
AUTO Operating Mode
In AUTO operating mode, the equipment will run as a Thermodynamic System and/or
electrical heater, (emersion heater) and the operation of the electrical heater is managed in an
optimized way to keep the water hot.
The electrical heater will start every time:
•
The user activates it manually (key E- Heater).
•
The contact LP opens (low external temperature, lack of fluid, leak in the circuit, etc.).
•
The compressor running time exceeds parameter T05*
•
The water temperature is below P08*
* Parameters T05 and P08 are adjustable and can be turned ON and OFF
BOOST Operating Mode
In BOOST operating mode, the equipment runs as a Thermodynamic electrical
heater, (emersion heater) simultaneously.
This mode enables the user to obtain hot water more quickly.
Once the panel is unlocked (pressure the OK button), the user can change the
operating mode when he/she wishes; he/she need only press simultaneously the
keys MENU + OK/LOCK for 3 seconds and select the mode that suits users’ needs
with the cursor.
After changing modes, check that the compressor is turned on.
