7.8 Electrical connections "Check" (function activated by the installer menu)
With this function you can control the electrical connections made during installation.
You can start the procedure from the installer menu, setting the parameter C1 ON and confirm by
pressing the knob. The procedure takes about 8 minutes during which the progress symbols flashes
on the display. To stop this procedure press "mode ".
If at the end of the procedure has the response "OK", the electrical connections were made properly.
If the response is "KO " recheck the electrical connections between indoor and outdoor units paying
attention to the numbers indicated on the terminals. Check probes cable.
7.9 Anti-legionnaire’s disease protection (function activated only through the installer menu)
If activated, the water heater automatically carries out the anti-legionnaire’s disease protection
function. The water is brought to a temperature of 65°C on a monthly basis and for a maximum time
of 15 minutes, so as to avoid germs from developing in the water tank and piping (provided the water
has not been brought to T>57°C at least once for at least 15 minutes). The first heating cycle is
performed 3 days after the function has been activated. As these temperatures may cause burns, it is
advisable to use a thermostatic mixer.
The achievement of temperatures above the set is marked with the symbol of the waves.
During the cycle of antilegionella will be displayed “ANTI_B” alternately to the mode of operation,
once the cycle is done the set temperature remains the original one.
In the event that is enabled the two-tier rate signal HC-HP, the function will take place during the
economic tariff. To stop press "on/off".

7.11 Operation with two-tier electricity rate
To be able to operate also on appliances with a two-tier rate system, the control logic calculates the number of
average hours a day during which the power supply is available in the economy mode (HC).
A self-learning function ensures that the appliance reaches the pre-set temperature in the time range during which the
economy rate applies; the maximum limit of hours is determined by the P9 TIME_W parameter; after the initial start-up
(or after switching off the hardware), the default setting is 8 hours.
