Set-Up and Use
7.11.3 Anti-Bacteria (Anti-Bact)
Factory Setting = No
- No legionella cycle except the return from vacation
and during exit frost over 3 days.
- During the legionella cycle the water temperature is
raised to 60°C by the heat pump.
- If the hot water is already set to 60°C (See Section
7.6) then legionella cycle will not run as
temperature is already obtained.
- If a cycle is interrupted by loss of electrical power
then the cycle will run at the next cycle period.
- The frequency of day can be adjusted according to
number of days
-During the anti-legionellosis cycle the temperature is
raised between 55°C and 70°C

Factory Setting = 1
- Mode 1 = Standard mode, automatic ventilation.
- Mode 2 = Manual mode, forced ventilation.
- Mode 3* = Ventilation during the heating of the
water and ventilation controlled by thermostat.
Thermostat is connected to input of the electronic card
in the heat pump water heater (see wiring diagram).
* In the case of activation of the PV mode, controlled
ventilation (Mode 3) is not available.
* The electric back-up immersion heater will activate
until the water temperature reaches 43
o
C. The heat
pump will complete the remaining charge to set
temperature.

It is possible to allow the operation of the immersion
heater along with the heat pump to prevent the
water temperature falling below a minimum comfort
temperature of 38°C. The immersion will then heat the
water to 43°C, once this temperature has been reached
the complete heating of the water heater.
- By default this is not active.
- In case of load shedding, the function <T

C Mini> is
not active.
7.11.6 Shedding
You can select which items are restricted from running
during load shedding (immersion heater or heat pump).

- Press ‘Menu’ to return to the main screen.
If the power contact is open:
- Mode 0 = Nothing is allowed to run.
- Mode 1 = Only the heat pump will operate.
- Mode 2 = Heat pump and boost are will operate
(neutralising the peak hours).
If the PV function is activated then the load shedding
from the voltage-free contact (Entrée 1/2) is not
possible. In this case it is necessary to go through the
programme scheduling (See Section 7.10).
- Press ‘Menu’ twice to return to the main screen.
- Press ‘Menu’ twice to return to the main screen.
- Press ‘Menu’ to return to the main screen.
Example:
ANTI-BACT=8,
TEMP.WATER=60C
the anti-legionellosis cycle
will run every 8 days at 10pm
