Operating mode 22
Depending on the adjustment angle for the “open”
position, the heat output can be reduced and a uniform
temperature distribution in the furnace or kiln can be
achieved nevertheless owing to intermittent operation
of the burner.

The opening speed is preset via the time t
1
for the entire
“low” to “high” setting travel.
Accordingly, the closing speed is set with t
2
for the en-
tire “high” to “low” setting travel.
The speeds are retained in both intermittent modes.
The running times are changed accordingly if the “ana-
logue” position (current signal) is moved. The “analogue”
position may also be higher than the “high” position in
this operating mode.
Possible parameter set for this operating mode:
P 68027, see page 45 (Parameter sets).
