”Extra hot water”
The function Extra hot water temporarily raises the tem-
perature of the hot water. The temperature is raised first
to an adjustable level with the compressor (menu 1.3) and
then an externally mounted immersion 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, periodically 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 re-
turn to the previously set function occurs after 12 hours.
Connection of ”Extra hot water”
The supply to the control signal/power supply to the im-
mersion heater is connected to the terminal block X6:22
(Max fuse 16 A and 250 V) and the control signal/power
supply out is on terminal X6:23.
There is a potential free relay for the Extra hot water func-
tion, 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
X6:18 to X6:22 and use X6:17 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.

or ”Off”. The factory setting is ”Off”.
Menu 1.5 Interval per. XHW [U]
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 activated when the
value changes. The digit within brackets indicates the
time in days that remain until the next periodic “Extra
hot water” increase. When periodic hot water heating
