A6:5 Extended economy mode active:
to The burner and heating circuit pump
A6:35 are switched off at a variable value,
adjustable from 5 to 35 °C plus 1 °C.
Mixer is being closed. The basis for
this is the adjusted outside tempera-
ture. This is derived from the actual
outside temperature and a time con-
stant that takes account of the way
an average building cools down.
A7:1 With mixer economy function (exten-
ded heating circuit pump logic):
Heating circuit pump also "OFF":
If the mixer has been trying to
■
close for more than 20 min.
Heating circuit pump "ON":
If the mixer changes to control

function.
If there is a risk of frost
