This setting will not appear in Active Mode
Reset all settings. First press to select.
Then set to ‘1’. Press again to reset all settings to
default settings. ‘0’ will exit reset without making any changes.
Displays the firmware version.
6. Operation
The heater constantly monitors and displays the temperature measured on the primary heating pad.
In Active Mode, the heater will apply power to the heating pads, as indicated by the OUT LED, until the
Set Point temperature is measured on the heating pad. In Thermo-Kinetic mode, the OUT LED will pulse
on and off, indicating a partial heating duty cycle.
6.1 Thermo-Kinetic Mode
Setup settings “Slow Down Temperature Delta” and “Hold Percentage” configure Thermo-Kinetic Mode.
The default settings are 10 degrees C Slow Down Delta and 10% power Hold Heating percentage.
When Thermo-Kinetic Mode is off (settings set to 0), power to the heatings pads will remain on until the
Set Point is reached. Then turn on again when the termperature reduces to below the Set Point. This will
generaly cause large temperature swings. When power is turned off to the heating pads, the temperature
will continue to rise for several seconds.
Thermo-Kinetic Mode reduces the average power to the heating pads by dynamically reacting to changes in
the temperature measurement and rate of change. Then, when the Set Point is reached, the average power
applied to the heating pads will be reduced to a level that dynamically compensates for heat loss, clamping
the temperature at the Set Point. The average power is set by controlling the on/off power duty cycle of the
heating pads, as indicated by the pulse rate of the OUT LED.
Slow Down Temperature Delta
Set to the number of degrees below the Set Point to begin reducing the average power to the heating pads.
Increasing this number will minimize over shooting the Set Point. The larger the number, the longer it will
take to reach the Set Point. A good starting value is 10 degrees.
The average power will be linearly reduced in proportion to the temperature delta below the Set Point.
Then the power level will be adjusted based on the temperature change over time (temperature derivative).
