III.m) Set the date
The function is used to set current date (day and month).
III.n) Pulser sensitivity
With this setting you can change the sensitivity of the pulser knob within a range from 1 to 3
(where 1 means the highest sensitivity).
III.o) Language selection
Using this function, the user selects the language in which the controller will be operated.
III.p) PID ON/OFF
This option enables the user to deactivate zPID control. In such a case, the controller functions
as a two-state regulator and the menu presents the following additional functions:
Fuel feeding time
This option is used to set the feeder operation time. The value should be adjusted to the type
of the CH boiler as well as the type of fuel used.
Feeder pause
This option is used to set the feeder pause time. The value should be adjusted to the type of
the CH boiler as well as the type of fuel used.
Incorrect operation and pause time may result in inefficient operation of CH boiler, i.e. unburnt
coal left or failure to reach the pre-set temperature of the CH boiler. Appropriate pause and
operation time ensures efficient operation of the CH boiler.
Blow force
This function is used to control the fan speed. The setting range is 1-100%. Initially the fan
always operates at a full speed, which enables successful activation even if the motor is dusty.
Temperature alarm
This function enables the user to define when the temperature alarm is to be activated. If the
CH boiler temperature does not reach the setpoint value during the period of time defined by
the user, an alarm is activated and the display shows an appropriate message. The alarm may
be deactivated by pressing OK (previous operation mode is restored).
Blow force
This function is used to control the fan speed. The setting range is 1-100% (the values may be
regarded as fan gears). The higher the gear is, the faster the fan works. 1% is the minimum
fan speed whereas 100% is the maximum fan speed.
Operation in sustain mode
This option is used to set the feeder operation time when the CH boiler operates in sustain
mode.
