The set timeline appears red-colored.
The pink line shows the eventual setting of the previous day that overruns in current day because the duration exceeds the
midnight.
It is necessary to enable the electric heaters in sanitary integration, by setting the parameter
R15 = 1
.
OPERATION:
•
When anti-legionella cycle is expected, the heat pump unit changes automatically into sanitary mode in order to reach the
setting values of the parameter
R27
(50°C.)
•
When the DHW temperature sensor meets the value of
R27
, the compressor will stop operation and the DHW electric heater
(DO = 26) will start after
R16
(1min).
•
The DHW electric heater turns off if one of the following conditions is fulfiled:
o
The DHW temperature sensor detects a temperature =
R25
(80°C), hysteresis 'cut-on' of 1°C.
o
The finishing of the programmed cycle.

".
2)
Select the mode in which the thermoregulation shall be carried out of the refrence zone, by setting the parameters from
