6.4.4 Setting the burner thermostat

Burner thermostat type: LAE AC1-5TS2RW
Function: The thermostat is used to adjust the temperature of the air blown into the dryer. The air
temperature is displayed in the thermostat screen during the drying process.
Indication: The LED lights located on the right side of the thermostat's numeric display, next to the
texts OUT1 and OUT2, show the status of the thermostat keys. OUT1 light on => 1
stage on. OUT2 light on => 2 stage on.
Setting: On the mobile dryer equipped with 1 stage burner (KP 26) the temperature is adjusted
by pressing shortly on the
temperature value stored in the memory. Now the value can be changed with arrow keys
up or down
pressed for 30 seconds, or if the
thermostat's memory.
On dryers equipped with 2 stage burners (KP26 H and KP-50H) the adjustment process
is the same, except the
fan. Press shortly on
set the desired value.
Note that the value of L1 has to be larger than the value of L2.
Example: 1 stage burner:
If the desired drying temperature is 70 °C, set the L1 value to 70. Note that this value
only limits the upper temperature value, which means that in case of low outdoor
temperature the intake temperature can remain below the set value.
If the burner flame is turned off due to excessively high temperature, the nozzle size
needs to be reduced. Otherwise the gasified fuel in the firebox can cause the flame to
flare up too strongly.
2 stage burner:
When setting the temperature for a mobile dryer with a 2 stage burner (KP 26H and KP-
50H), both temperatures L1 and L2 can be used. The L1 value, adjust the value of the 1
stage flame, and L2 is the value of the 2 stage flame. The values determine the time
when the flame is extinguished. The idea is to adjust the temperature with the flame of
the 2nd stage. The flame of the 2nd stage is extinguished when the temperature is too
high. The flame of the 1st stage should be on at all times, it should not be extinguished.
If the 1st flame is extinguished, the nozzle is too large and needs to be reduced. The
temperature difference between L1 and L2 has to be about 10 °C.
Example. If the desired drying temperature is 80 °C, the L1 value is set to 90 °C and
the
L2 value is set to 80 °C.
