General Operation
The temperature sensor provided is what determines the cooling or heating. When it senses the
set temperature is reached, the unit will pause heating or cooling, until the temperature change
is sufficient to cause it to continue.
Ideally, you will use this unit with an Apollo Conical Fermenter or similar fermenter with a
thermowell for the temperature sensor probe. This allows the temperature inside the liquid to be
measured.
Alternatively, you can tape the sensor probe to the outside wall of the fermenter or keg,
however, this will not be quite so accurate.
Setting the Temperature and Other Settings
This is done via the STC-1000 Temperature Control Panel.
It should be preset to 18°C (64.4°F).
There are four settings that can be configured on the
STC-1000 temperature controller.
F1
is the temperature setting for the sensor to reach.
F2
is the hysteresis setting. Once the temperature set via F1 is achieved, the unit
pauses any heating or cooling.
The hysteresis value is the temperature difference threshold at which the unit resumes
heating or cooling. Setting this value too small will result in excessive heat / cool
cycling. Typically, 0.5°C (or 1°F) should work well.
Example: with a hysteresis value of 1° and a temperature setting of 5°, the unit will
reach 5° and then pause actively heating or cooling. If temperature rises by 1° above
5°, it will then start cooling until it reaches 5° again. Or if the temperature drops by 1°
below 5°, it will start heating until it reaches 5°.
F3
is a cooling delay setting which can be set to zero as the Thermentor King can
switch between cooling and heating without ill effects. If the unit has been actively
cooling and stops due to reaching the set temperature, it will not start cooling again
until the cooling delay is passed (and the temperature is above the set hysteresis
value).
F4
is a temperature calibration offset value. Set this value if you test the sensor in a
liquid with a known, validated (from an accurate thermometer) temperature, and the
STC-1000 reads a different temperature.
Set this value to the difference between the cabinet sensor reading and the validated
temperature
