2.12.3 Converting the power supply connection
To restore the factory settings, the connection values must be
re-entered .
To find out whether your temperature control unit is convertible from 230V 1~ 50Hz to
400V 3~N 60Hz, refer to the datasheet from page 99 in section
»Annex«
.
▪
The maximum current consumption at 230 V operation is just below 16 A.
However, there are 230 V power supplies with a smaller fuse protection. During initial startup you
will be prompted to adjust the power consumption of the temperature control unit to your power
supply.
The following can be selected:
16 A (100 % heating power with
switched on
compressor)
13 A (reduced heating power with
switched on
compressor)
10 A (reduced heating power with
switched on
compressor)
A disconnected compressor does not effect the heating power:
16 A (100 % heating power with
switched off
compressor)
13 A (100 % heating power with
switched off
compressor)
10 A (100 % heating power with
switched off
compressor)
There is no effect on the control behavior. You can also subsequently change the maximum pow-
er consumption in the Pilot ONE menu.
▪ The supply voltage for some temperature control units must be selected during initial start-up.
This selection can be subsequently changed in the Pilot ONE menu ([Category menu] > [Installa-
tion] > [Voltage supply]). The menu option “Voltage Supply” is visible only if the temperature con-
trol unit supports the manual conversion of the voltage supply. The supply voltage must be rese-
lected if the temperature control unit has been reset to the factory settings.
2.12.4 Connecting the functional earth
PROCEDURE

If required, connect the temperature control unit’s
>Functional earth terminal<
[87] to the
building’s grounding point. Use a ground strap for this purpose. For the exact position and thread
size please refer to the wiring diagram from page 99 in Section
»Annex«
