Extended economy function dampened outdoor temp.

bled
A6:5
to
A6:35 Extended economy mode active.
The burner and heating circuit pump
will stop at a variable value, adjusta-
ble between 5 and 35 °C plus 1 °C.
Mixer is being closed. The basis for
this is the adjusted outside tempera-
ture. This is composed of the actual
outside temperature and a time con-
stant that takes account of the way
an average building cools down.
Extended economy function mixing valve
A7:0 Without mixer economy function
(only for heating circuits with mix-
er) 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 longer than 20 min.
Heating circuit pump "ON":
■
If the mixer changes to control
function
■
If there is a risk of frost
Pump idle time, transition reduced mode
A9:7 With pump idle time: heating circuit
pump "OFF" if set value is modi-
fied by changing the operating
mode or changing the set room
temperature A9:0 Without pump idle time
A9:1
to
A9:15 With pump idle time, adjustable from
1 to 15. The higher the value, the
longer the pump idle time.
