1. Overview
This temperature controller contains one temperature probe and
two independent outputs. One output is for cooling and the other
one is for heating. It can be used for applications such as heating
during mashing or fermentation, or for cooling post-boil and
during fermentation.
This controller is a plug and play controller. No wiring is needed
for the heater or cooler. Both the heating and cooling control
modes are simple on/off control, similar to a mechanical
thermostat but with much higher precision due to an adjustable
hysteresis band, precise sensor and digital read out. Anti-short
function is also provided for cooling to protect a refrigerator
compressor from being turned on while at high pressure which
could damage it.
Different operation temperature ranges of the two outputs can be
set separately. Once the cooling range is set, the controller
program will automatically limit the heating range to prevent both
heating and cooling from being turned on at the same time.
A digital silicon band gap sensor is used with the advantage being
that it is much more reliable in a moist environment than a
thermistor sensor. It can be immersed over an extended period of
time. It also has more uniform accuracy over an entire specified
temperature range.

4. Setup Flow Chart
When the controller is plugged in, and the probe is attached, it
will display the measured temperature. The controller will keep
running according to the saved settings. If the temperature
sensor is shorted or removed, the controller will display “Err”.
Please see Figure 2 for the flow chart to set the parameters.
