Extended economy mode
enabled, i.e. the burner and
heating circuit pump will be
switched OFF at a variable
value, adjustable between
5 and 35 °C plus 1 °C. The
mixer is closed. This value
is based on the adjusted
outside temperature, com-
prising the actual outside
temperature and a time
constant. The time con-
stant takes the cooling
down of an average build-
ing into account.
Recommended setting:
"A6:16" to "A6:18"
