Line no. Operating line
2454 Switching diff on HCs
The switch-on threshold is calculated from the required setpoint minus the switch-on
differential. The parameter represents the switch-on differential used for requests from
space heating.
Line no. Operating line
2455 Switching diff off min HCs
The switch-off threshold is calculated from the required setpoint plus the switch-off
differential. The parameter represents the switch-off differential used for requests from
space heating. During the settling time, the switch-off differential can vary between the
minimum and the maximum value. At the end of the settling out process, it is always the
minimum switch-off differential that is used.
Line no. Operating line
2456 Switching diff off max HCs
The switch-off threshold is calculated from the required setpoint plus the switch-off
differential. The parameter represents the switch-off differential used for requests from
space heating. The maximum switch-off differential is only used during the settling out
process.
Line no. Operating line
2457 Settling time HCs
This parameter represents the period of time after the burner was switched on during
which the switch-off threshold can be calculated based on the maximum switch-off
differential. The parameter is used for requests from space heating.
Line no. Operating line
2460 Switching diff on DHW
The switch-on threshold is calculated from the required setpoint minus the switch-on
differential. The parameter represents the switch-on differential used for DHW heating
requests.
Line no. Operating line
2461 Switching diff off min DHW
The switch-off threshold is calculated from the required setpoint plus the switch-off
differential. The parameter represents the switch-off differential used for DHW heating
requests. During the settling out process, the switch-off differential can vary between
the minimum and the maximum value. At the end of the settling out process, it is always
the minimum switch-off differential that is used.
Line no. Operating line
2462 Switching diff off max DHW
The switch-off threshold is calculated from the required setpoint plus the switch-off
differential. The parameter represents the switch-off differential used for DHW heating
requests. The maximum switch-off differential is only used during the settling out
process.
