Min. flow temperature heating circuit
C5:20 Electronic minimum flow tempera-
ture limit 20 °C C5:1
to
C5:127 Minimum limit adjustable from 1 to
127 °C (limited by boiler-specific pa-
rameters)

Heating program changeover
d5:0 External operating program
changeover switches operating
program to "Constant operation at
reduced room temperature" or
"Standby mode" d5:1 The external operating program
changeover switches to "Constant
operation at standard room tempera-
ture" (subject to coding addresses
"3A", "3b" and "3C")
Ext. heating program changeover to heating circuit
d8:0 No operating program changeover
via EA1 extension d8:1 Operating program changeover via
input DE1 at EA1 extension
d8:2 Operating program changeover via
input DE2 at EA1 extension
d8:3 Operating program changeover via
input DE3 at EA1 extension
