11.2 Working Principle
The valve will close to stop heating when the current temperature reaches the SP(stop heating temperature) and
will open to start heating when it reaches the ST(start heating temperature).
In order to prevent the water in the pipe
from freezing, the control valve will
automatically activate the heating
function when it detects that the ambient
temperature is too low.
Enabled when the
temperature is
below 5.0℃�.

has not been opened for a long time.
After enabling the vacation mode function,
the control valve will close the heating
function but will maintain the function of
detecting the indoor temperature, and you
