When manual control is activated, a change to the basic display must be made where
the service/special mode symbol
appears. When pressing the Info button, info

When the Controller stop function is activated, the burner’s output set via the Controller
setpoint is immediately demanded from the boiler.
The burner can be controlled manually via the Controller stop function. The control
algorithm of the LMS14... is overridden by the output preselected by the operator. But
the 2-position controller remains active because the burner is put out of operation if the
flow temperature reaches the maximum boiler temperature (Setpoint max (2212)).
When the boiler temperature reaches the switch-off point, the Controller stop function is
automatically deactivated. The function can be activated again as soon as the boiler
temperature drops below the switch-off point.
In that case, the burner is put into operation only when the boiler temperature drops by
the Switching differential on heating circuits (Switching diff on HCs (2454)) below the
switch-off point.
Note!
The preselected output [%] refers to the modulation range in Heating mode. A
preselected output of 0% corresponds to the minimum heat output.
During the time the Controller stop function is active, the boiler pump keeps running to
ensure the produced heat is carried to the consumers’ heating circuits. DHW heating
equipment is not being served during the periods of time the Controller stop function is
active.
Note!
The Controller stop function is automatically ended after 4 hours.
