5.4.3.4 Controlled by Atmospheric Conditions
5.4.3.5 Limiting the Firing Rate Controller
P no. Description Attributes
48 Controller setpoint 1 (for constant control/min. value for control by atmospheric condition)
Controller setpoint 1 minimum. Setting the minimum set point for the controller controlled by
atmospheric conditions in °C or bar.
The setting is active if the input ’Setpoint changeover’ = 0.
If the firing rate controller is configured as a constant controller, setpoint 1 is set here

49 Controller 1 maximum value (only for control by atmospheric conditions) V1.0.0.0
Controller setpoint 1 max. for control by atmospheric conditions
Enter the setpoint maximum for the controller in °C or bar. The setting is active if the input
’Setpoint changeover’ = 0.

50 Controller 2 setpoint (constant control/min. value for control by atmospheric conditions) V1.0.0.0
Enter the setpoint minimum for the controller controlled by atmospheric conditions in °C or
bar. The setting is active when the input ’Setpoint changeover’ = 1.
If the firing rate controller is configured as a constant controller, setpoint 2 is set here.

52 Temperature range minimum
53 Temperature range maximum V1.0.0.0
Upward limitation of the set point for control by atmospheric conditions 0,1 °C or Digit.
This is the lower limit of the outdoor temperature.
0 ... 249 = 0,0 ... 24,9 °C
250 ... 500 = -25,0 ... 0,0 °C
Upward limitation of the set point for setpoint shift in 0,1 mA or Digit. This is the lower limit of
the current input (min. = 0 max. = 500).
0 = 0,0 mA
40 = 4,0 mA
200 = 20,0 mA
