This function allows to set the control of the correct operation
in domestic hot water production; once the chiller starts to
produce domestic hot water, this control checks the trend of the
temperature inside the DHW storage tank; if this temperature
does not increase or decrease for the period of time specifi ed
in this parameter, the system will assume a problem with the
heat pump and will activate the supplementary resistance on the
DHW storage tank to meet the domestic hot water demand (to
deactivate this control, the time must be set at 0);
to set this
value it is necessary to:
(1) Enter modifi cation mode by pressing the
C
key; after this
key has been pressed, the current setting will be highlighted.
(2) Press the
A
or
B
key to modify the setting of the minutes
after which to activate the supplementary resistance on the
DHW storage tank.
(3) Press the
C
key to confi rm the value entered; once this
key has been pressed, the current setting will be highlighted
normally, thus indicating that the modifi cation procedure has
concluded.
After the data has been entered, it will be possible to:
- Pass on to the following window by pressing the
B
key.
- Go back to the previous window by pressing the
A
key.
- Press the
D
key to return to the selection of the menus.

The proposed example hypothesises
the safety control to be activated after
an indicative time of 15 minutes, as,
based on the volume of the DHW storage
tank, the exchange surface of the heat
exchanger in the storage tank and the
intended thermal output of the heat
pump, this value will likely allow to identify
functioning problems with the heat pump.
