The functions of the FM443
3
Press and hold the "Display" button and turn the dial.
Now you can set the integration of the buffer tank.
No buffer integration
If you set the integration to "none", then the module assumes that
no buffer tank is to be taken into consideration.
Buffer bypass
If you set "buffer-bypass" for the integration, the module assumes
that the solar system will also be used for heating and the buffer
tank should be integrated to increase the return temperature of a
standard heat source.
Buffer integration as dual-purpose tank
If you set "pendulum DHW 1/DHW 2" for the integration, the
module assumes that not just the solar system provides its energy
to the buffer tank, but the standard heat source also supplies its
energy into the buffer tank and the system is supplied entirely or
partially from the buffer tank.
Here it is possible to distinguish whether tank 1 or tank 2 should
function as a dual-purpose tank.
