Overview

4. Operating modes.

4.1 Modes in "Thermodynamics only" installation:

AUTO: The setpoint temperature is thus automatically adjusted between 50 and 62° C depending on the
consumption history. The water heater preferentially selects the heat pump to operate. The electrical backup
can be activated automatically in support.
MANUAL - Passive ECO: The user chooses the fixed setpoint temperature between 50 and 62° C. The water
heater preferentially selects the heat pump to operate. The electrical backup can be selected automatically to
ensure sufficient hot water volume.
MANUAL - Active ECO: The user chooses the fixed setpoint temperature between 50 and 55° C. The water
heater works exclusively with the heat pump to maximize savings. The electrical backup is only authorised to
function when the air temperatures are outside the operating range.

4.2 Modes in "Boiler backup" installation:

MANUAL: The user chooses the fixed setpoint temperature between 50 and 62° C. (55° C if Active ECO). The
water heater preferentially selects the heat pump to operate. The electrical backup can be selected
automatically to ensure sufficient hot water volume. If the boiler is not available to provide support (boiler
shut down for example), the electrical backup will be activated.
SMART Energy operation:
A heat pump draws available energy from the
air and transforms this energy into hot water by
the process of heat exchange around the tank.
The heat pump's performance will therefore be
improved with settings that encourage these
energy exchanges; namely, with air that is hot
and with cold water in the tank. Our product
continuously calculates which energy is the
most economical based on the air and water
temperature. This SMART Energy function can
therefore decide to start heating with the heat
pump, before producing the last few degrees
using the boiler backup.
In addition, the Smart Energy function can be set with 4 different priority levels:
The backup will only be active at the end of heating for very low air temperatures (<7° C)
Heat pump priority
The backup will only be active at the end of heating and ± earlier depending on the air
Heat pump
optimised
temperature The heat pump is active at the start of heating and ± later depending on the air temperature
Boiler optimised
The heat pump is active at the start of heating and for air temperatures > 10 ° C.
Boiler priority

4.3 Modes in "Solar backup" installation:

The water heater only operates during periods when there is no solar production (when it receives a signal
from the solar station). During periods of solar production, the internal heat exchanger, the heat pump and
the electrical backup will not produce hot water.
MANUAL: The user chooses the fixed setpoint temperature between 50 and 62° C. (55° C if Active ECO).
The electrical backup will never work if the "Electrical backup" setting is deactivated.
