5 Firing Rate Controller (optional)
5.1.7 Manual Control
CAUTION!
In manual mode, the firing rate controller’s functions such as startup circuit and control ther-
mostat are switched off. Therefore you should always monitor the system continuously when
using manual control. You can check the safety limiter by changing the setpoint.
5.2 Control Setting
5.2.1 Meaning of the Display
5.2.2 How to Adjust the Burner Firing Rate Controller
Only adjust the burner firing rate controller with the parameters.
The output controller’s firing rate specification can be
overwritten by turning the selector switch (2) to LOAD
RATING (firing rate) and pressing the Channel 1 switch
(4) upwards.
This manual firing rate control is cancelled by pressing
the Channel 2 switch (4) downwards.
In manual mode, the shut-off limit can be found in Func-
tion (from software version 3.1 onwards). Hence you
cannot use the manual mode to test the safety limiter.
