-
S2 E1
- the temperature gauge in the water heater lower part is cut/missing;
-
S2 E2
- the temperature gauge in the water heater lower part is in short-circuit;
-
S3 E1
- the collector thermostat is damaged. It is either interrupted or switched off. Only
electric heating modes shall be operative;
-
S3 E2
- the collector thermostat is damaged. It is in short-circuit. Only electric heating
modes shall be operative;
-
S3 Frost
- the collector temperature gauge has registered a temperature lower that the
critical minimum values set and it is possible that the fluid is frozen. Only the electric
heating regimes shall operate. The system integrity must be checked and only then
switched on again;
-
S5 E1
- the temperature gauge at the compressor output is cut;;
-
S5 E2
- the temperature gauge at the compressor output is in short-circuit;
-
S6 E1
- the temperature gauge at the defrost inlet is cut;
-
S6 E2
- the temperature gauge at the defrost inlet is in short-circuit;
-
S7 E1
- the temperature gauge at the defrost outlet is cut;
-
S7 E2
- the temperature gauge at the defrost outlet is in short-circuit;
-
S8 E1
- the temperature gauge for environmental temperature is cut;
-
S8 E2
- the temperature gauge for environmental temperature is in short-circuit;
-
Frost
– the water temperature in the tank is < 0ºC (frozen water);
-
Overheat1
– collector temperature is above the values set for switching on the collector
overheat protection pump, however the water inside the tank is within the maximum
acceptable limits and the collector overheat protection function shall not be activated.
-
Overheat2
– the collector thermostat has registered temperature higher that the critical
maximum values set. Only the electric heating regimes shall operate. The system
integrity must be checked and only then switched on again.
-
High I
– current protection is active;
-
High Press
– heat pump high pressure protection is active;
-
L Fail
– unsuccessful legionella protection cycle;
-
Long Defr
– too long defrosting process;
-
Freq Defr
– frequent defrosting processes;
-
Low U
– high tension protection is active;
-
High U
– low tension protection is active;
-
Leakage –
leak from heater to water heater hull. In this case the appliance shall switch
off and its subsequent switching on shall be possible only after switching off from the
apartment switchboard.
-
No heat
– heater or heat pump are switched, but the water temperature in the tank does
not rise.
-
No errors
– no errors reported.
If the screen displays electricity consumption meter (daytime or night-time rate), by holding the
Enter button for three seconds the meter shall be reset.
USER CONTROLS
In order to enter in user controls mode it is necessary to hold for a second and half button F.
User controls are accessible both in switched on and off condition. When the controller is in
user controls mode the following rules apply:
• Button
Enter
switches to next field to edit, if any.
• Buttons
▲
or
▼
correspondingly increase or decrease the current value. If the button is hold
on the value changes automatically in the corresponding direction. When the settings provides a
list of options to choose from, then button
▲
provides for selecting next one, while button
▼
–
for the previous one, if any.
