Switching on the heating via telephone
The controller can be switched to heating operation
(
B) by means of a telephone switch. The hot water
function, operated by an external hot water tank, is
released for this period.
Connecting a telephone switch:
Connection terminals 3+4.
As soon as these terminals detect a short circuit,
the controller switches to heating operation (with
set room temperature I) and releases the hot water
preparation. When the short circuit is cleared, heating
resumes according to the set mode of operation or the
set heating program.
