which the circulation pump will start and stop.
max. tank temperature, max. solar collector temp.: Here,
you can set the maximum temperatures in the tank and
solar panel respectively at which the circulation pump
will stop. This is to protect against excess temperatures
in the solar tank.
max solar pool temperature: Here, you can set the
maximum temperature at which the solar panel stops
pool heating (if the installation is structured in this way).
Pool heating can only occur if there is a heat surplus
once the heating and/or hot water demand is met.
If the unit has an anti-freeze function and/or solar panel
cooling you can activate them here. When the function
has been activated, you can make settings for them.

solar panel is higher than this setting, at the same time
as the temperature in the solar tank is higher than the
set maximum temperature, the external function for
cooling is activated.
See the accessory installation instructions for function
description.
MENU 5.3.7 - EXTERNAL ADDITION
Make settings for external addition here. External addi-
tion is for example external oil, gas or electric boiler.
If the external addition is not step controlled, in addition
to selecting when this should start also set the run time
for the addition.
If the external addition is step controlled you can select
when the addition is to start, set the maximum number
of permitted steps and whether binary stepping is to be
used.
If you select "prioritised additional heat" the heat is used
from the external addition instead of the heat pump.
