Linear Heat
When Linear Mode is enabled:
•
Between the Heat Temperature and the Target temperature, heaters do not operate (meaning,
the output voltage is 0).
•
Between the Heat Temperature and the Low Difference Below Heat, heaters operate at the
minimum voltage output.
•
If the temperature continues to drop, the voltage output increases until it reaches the maximum
voltage output at the High Difference below Heat.
In this example:
•
Target Temperature is 80°
•
Temperature Curve Heat Off is 78°.
•
Low Heat Differential is 1°.
•
High Heat Differential is 8°.
o
If the temperature is between 77° to 78°, the output voltage is the minimum voltage
defined in Installation > Analog Output (1 volt in this example).
o
If the temperature continues to drop, the output voltate increases until it reaches the
maximum voltage defined in Installation > Analog Output. Output increases or
decreases to keep the temperature within the Target Temperature and Heat Off band.
•
Define the parameters:
o
Low Difference Below Heat: Temperature difference between the Heat Off parameter
at which the variable heater begins to function.
