Note!
For boilers without control input, the functions for boiler control
can be accessed by the simulation of temperature values.
To enable reheating or anti-legionella functions, the corresponding
boiler temperature must be increased at the boiler control.
The differential temperature controller smart Sol regulates the boiler control functions
by a xed value resistance simulating a charged buffer tank for the boiler.
The resistance value depends on the type of sensor the heating
is adjusted to - this information is provided in the boiler manual.
Connection provided at the
REL terminal block, as illustrated.
