Coding
Coding in the delivered condition
Maximum buffer cylinder temperature
34:85 Max. average temperature of the
heating water buffer cylinder, 85 °C
(upper limit of control range)
Minimum buffer cylinder temperature
35:60 Min. average temperature of the
heating water buffer cylinder, 60 °C
(lower limit of control range)
Buffer cylinder charging to sensor
36:3 The boiler charges the heating wa-
ter buffer cylinder up to the third
buffer temperature sensor.
Buffer cylinder charging up to temperature
37:70 The boiler charges the heating wa-
ter buffer cylinder until the temper-
ature of 70 °C is reached at the se-
lected sensor (code "36:1-5", buf-
fer cylinder group).
Boiler start, sensor
39:1 If the set system temperature at
the first buffer temperature sensor
(top) is undershot, the boiler starts
