Readout of the measured air inlet temperatures of the individual tunnel sensors.
The value # indicates that the sensor concerned is either faulty or not connected.
Desired temp.
Readaout of the required air inlet temperature (°C/°F). This is, in fact, the end value
air inlet temperature, as long as the compost temperature has no influence.
Min
Setting of the minimum air temperature (°C/°F). When the
Air temperature control
value
has risen above this minimum value it will never drop below this minimum
value.
Max
Setting of the maximum air temperature (°C/°F). When the
Air temperature control
value
has dropped below this maximum value it will never rise above this maximum
value.
Heat up/h
Setting of how many degrees the air inlet temperature may rise every hour, if the air
inlet temperature control value has to go to a higher value.
Cool down/h
Setting of how many degrees the air inlet temperature may drop every hour, if the
air inlet temperature control value has to go to a lower value.
Control
Setting of the type of air inlet temperature control:
●
INLET 1
: The air inlet temperature control is based on the temperature
measured by air inlet sensor 1.
●
INLET 2
: The air inlet temperature control is based on the temperature
measured by air inlet sensor 2.
●
INLET 3
: The air inlet temperature control is based on the average temperature
of air inlet sensors 1 and 2.
Margin compost
Setting of the number of degrees the measured compost/tunnel temperature may
differ from the compost/tunnel temperature control value, before the Lumina 750
starts adjusting the air inlet temperature. The Lumina 750 can correct the compost/
tunnel temperature by adjusting the air inlet temperature.
Correction
Setting of the extent to which the Lumina 750 must correct the air inlet temperature.
If this value is 0, the Lumina 750 will control the air inlet temperature independently
to the compost/tunnel temperature.
Compost/tunnel temperature control value 55.0°C (131 °F)
Measured compost/tunnel temperature 57.0°C (135 °F)
Required air inlet temperature 50.0°C (122 °F)
Margin compost/tunnel temperature 1.0°C (1.8 °F)
Correction 2.0°C (2.0 °F)
The air inlet temperature control value will be:
50.0 + (55.0 - (57.0 - 1.0)) × 2.0 = 48.0°C
122 + (131 - (135 - 1.8)) × 2.0 = 148 °F
Control time
Setting to control the extra adjustment to the air inlet temperature when the compost
temperature remains different. A small control time means a quick extra adjustment;
a large control time means a slow extra adjustment.
●
00:00 (hh:mm): No extra adjustment to the control value if there is a difference
●
xx:xx (hh:mm): Adjust the control value every x minutes, depending on the
difference
