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 infor-
mation is provided in the boiler manual.
Connection provided at the
REL terminal block, as illustrated.

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.
