Installation / Adjustment
Hot water
The need of hot water production is created when the
temperature on the hot water sensor (VVG) drops below
the temperature set in menu 1.1. The need ceases when
the temperature exceeds the set temperature in menu 1.2.
When two or more compressors are programmed for hot
water charging, these are engaged and disengaged with
0.5 degrees minus difference for starting and stopping.The
value can be set in menu 1.8. That’s to say, if compressor 1
starts at 50 °C and stops at 55 °C then compressor 2 starts
at 49.5 °C and stops at 54.5 °C i.e. each F1330 connected
for possible switching between hot water and heating has
its own shuttle valve.
Hot water mode normally has priority over heating mode.
However, it is possible to set the period time and max time
for hot water production in menus 1.6 and 1.7.
When in heating mode, the hot water temperature is
measured before stopping. With less than 2 degrees to hot
water start, hot water mode will start using one compres-
sor directly without stopping, once the heating require-
ment is reached.
Connection of hot water production
The shuttle valve (VXV) is connected to the terminal block
X6:3 (230 V), X6:4 (N), X6:5 (230 V with heat production)
and X6:6 (230 V with hot water production).
The hot water sensor (VVG) is installed in the water heat-
er’s submerged tube. The sensor must make good contact
with the measurement area to give the best function. The
sensor is connected to screw terminals X4:11 and X4:12 on
the EBV-card.

hot water production
Menu 1.1 Start temperature HW [U]
The temperature when the heat pump starts to work
with the hot water production is set here. When brack-
ets are shown, this means the high pressure pressostat
has tripped during hot water charging and F1330 has
automatically lowered the set temperature by the value
in brackets. The reduction is removed when the value is
changed. The value is adjustable between 5 and 55 °C.
The factory setting is 45 °C.
Menu 1.2 Stop temperature HW [U]
The temperature when the heat pump stops working
with the hot water production is set here. When brack-
ets are shown, this means the high pressure pressostat
has tripped during hot water charging and F1330 has
automatically lowered the set temperature by the value
in brackets. The reduction is removed when the value is
changed. The value is adjustable between 20 and 60 °C.
The factory setting is 50 °C.
Menu 1.6 Periodtime HW/Heat. [U]
The length of the period time for hot water production
and heating are set here. The value is adjustable between
0 and 60 minutes. The factory setting is 60 minutes.
Menu 1.7 Maxtime HW-product. [U]
Here you select how much time of the period time (menu
1.6) is to be used to heat the hot water when there is a
need of both heating and hot water. The value is adjust-
able between 0 and 60 minutes. The factory setting is 60
minutes.
