Default settings

The default DHW temperature is set to 50°C.
The following table shows the other default settings in the control system:
Menu Description
00 Auto heating curve (value 43 relates to the number of the curve and
has no units of measure, A indicates that it is in automatic mode only)
01 Initial (desired) room temperature
02 House heating mode
03 Defrosting cycle
04 Coil temperature threshold for starting defrosting
05 Coil temperature threshold for stopping defrosting
06 Maximum defrosting period
07 Domestic hot water hysteresis setting (i.e. number of degrees below
set point where the DHW will start again)
08 Heating hysteresis setting (i.e number of degrees below set point
where the heating will start again)
09 Overheating of electronic expansion valve in heating mode
10 Overheating of electronic expansion valve in cooling mode
11 Time delay for compressor start-up after power-up (for example, after
a power cut-off)
12 Circulation pump operation mode
13 Internal electrical heater operation during defrosting
14 Automatic legionella protection function
15 Internal electrical heater start option
16 Air temperature restriction for when internal electrical heater can
manually be started, that is, must be lower than this value.
17 Additional hysteresis in relation to menu 08 for when internal electri-
cal heater can manually be started.
18 Additional temperature hysteresis for hot water tank electrical heater
in relation to menu 07 for when the electrical heater will start.
19 Hot water tank electrical heater startup delay
20 Return water temperature
21 Supply water temperature
22 Coil temperature in heating mode (T7)
23 Coil temperature in cooling mode (T8)
24 Air temperature (T1)
25 Hot water tank temperature (T3)
26 Buffer tank temperature (T2)
27 Return gas temperature of compressor (T5)
28 Exhaust gas temperature of compressor (T4)
