start delta-T, stop delta-T: Here you can set the tem-
perature difference between solar panel and solar tank
at which the circulation pump is to start and stop.
max. tank temperature, max. solar collector temp.:
Here you can set the maximum temperatures in tank
respectively solar panel at which the circulation pump
is to stop. This is to protect against excess temperatures
in the solar tank.
max solar pool temperature: Here you can set the
maximum temperature where the solar panel stops
heating pool (if the unit is made up in such a way). Pool
heating can only occur if there is a heat surplus when
heating and/or the 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.
freeze protection
anti-freeze temperatur e: Here you can set the temper-
ature in the solar panel at which the circulation pump
is to start to prevent freezing.
solar panel cooling
start solar collector cooling: If the temperature in the
solar panel is greater than this setting at the same time
that the temperature in the solar tank is greater than
the set maximum temperature, the external function
for cooling is activated.
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 addi-

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.
See the accessory installation instructions for function
description.
