Codes
Code 1
(cont.)
Buffer (heating water buffer cylinder)
Coding
Coding in the delivered condition
Buffer cylinder temperature reheating suppression
33:0 Reheating suppression disabled
Maximum buffer cylinder temperature
34:... Maximum average temperature of
the heating water buffer cylinder
(upper limit of control range)
Minimum buffer cylinder temperature
35:... Minimum average temperature of
the heating water buffer cylinder
(lower limit of control range)
Buffer cylinder charging to sensor
36:3 The boiler charges the heating wa-
ter buffer cylinder up to buffer tem-
perature sensor 3.
Buffer cylinder charging up to temperature
37:... The boiler charges the heating wa-
ter buffer cylinder up to a tempera-
ture of ... °C at the selected sensor
(code "36:1-5", buffer cylinder
group) is reached.
Boiler start, sensor
39:1 If the set system temperature at
buffer temperature sensor 1 (top)
is undershot, the boiler starts.
Additional heat generator
Available if code "Additional boiler" is set to "Yes".
