Extra hot water
The menu can be accessed by pressing
the Extra hot water button. See the sec-
tion Control, for a detailed explanation.
Menu 1.3 Stop Temp. compr XHW
The temperature that the compressor shall stop
producing hot water in Extra hot water and allow
the additional heat (XVV) to take over is set here.
The value is adjustable between 20 and 60 °C, or
“Off”. The factory setting is 50 °C.
Menu 1.4 Stop temperature XHW
The required temperature for Extra hot water,
when the additional heat shall stop during hot
water production is set here. The value is adjust-
able between 50 and 80 °C, or ”Off”. The factory
setting is ”Off”.
Menu 1.5 Interval per. XHW
How often the hot water temperature is increased
from the normal level to the extra hot water level
is shown here. Periodic Extra hot water is acti-
vated when the value is changed. The number in
brackets concerns the time in days that remain
until the next periodic Extra hot water increase.
The value is adjustable between 1 and 90 days,

The function Extra hot water temporarily raises the
temperature of the hot water. The temperature is
raised first to an adjustable level with the compressor
(menu 1.3) and then an externally mounted immer-
sion heater takes over, if required, to increase the last
degrees (menu 1.4).
Extra hot water can either be activated via the keypad
on the display, automatically at a specific time, periodi-
cally or via an external contact.
When the external contact is used, this should be
potential free and momentary. The function is activated
when the contact is closed for at least one second. An
automatic return to the previously set function occurs
after 12 hours.
Connection of Extra hot water
The supply to the control signal/power supply to the
immersion heater is connected to the terminal block
X6:17 (Max fuse 16 A and 250 V) and the control sig-
nal/power supply out is on terminal X6:18.
There is a potential free relay for the Extra hot water
function, which can be used for the control voltage or
power supply (max 16 A, 250 V). When you use the
relay for the control voltage, the power supply can be
strapped from X6:14 to X6:17 and use X6:13 as N, but
the max. current must then be 0.4 A and the control
voltage will be 230 V. If you take more power than this
from X6:14 the Base card can be overloaded.
The external contact function is connected to terminal
X4:3 and X4:4 on the EBV-card.
