TD120-W WIRELESS TEMPERATURE CONTROLLER
INSTRUCTION MANUAL
Version 1.0 (August, 2019)
1. Overview
This temperature controller contains one temperature probe and two
independent outputs. One output is for cooling device such as
refrigerator and the other one is for heating device. It can be used for
applications such as beer fermentation or convert a refrigerator to
kegerator. By using both cooling and heating devices, the refrigerator
can be controlled at specific temperature regardless in hot summer or
cold winter.
This controller is a plug-and-play controller. No wiring is needed for the
heater or cooler. Both heating and cooling control modes are simple
on/off control, similar to a mechanical thermostat but with much higher
precision due to adjustable hysteresis band, precise sensor and digital
readout. Anti-short function is provided for cooling to protect the
compressor from being turned on with high pressure Freon.
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. The advantage is being much
more reliable in moisture environment than thermistor sensor. It can be
immersed over extended period of time. It also has a more uniform
accuracy over an entire specified temperature range.
Reversed logic function has been added to this model, which can
activate the one single output when temperature is in a range set by
HSP (heating setpoint) and CSP (cooling setpoint). For details, see
note 7 on page 3.

*: Either the heating or the cooling device is limited to 10 Amps. The output voltage is the
same as the input voltage. When the controller is plugged into 120V AC, the output will
be 120V AC. If the controller is connected to 240V AC, the output will be 240V AC also.

4. WIFI Function
To reset the WIFI function of this controller, push down and hold SET
key and down arrow key at same time for about 3s. Then WIFI
indicator will be fast blinking (4 Hz). It indicates this controller is waiting
for new setup now. After the controller is setup to your phone
successfully, the WIFI indicator will be OFF at most of the time. For
details, see supplementary manual for details.
5. Setup Flow Chart
When the controller is powered on, it will display the measured
temperature. The controller will keep running according to the saved
setting. If the temperature sensor is shorted/disconnected, the
controller will display “Err”. Please see Figure 2 for the flow chart to set
the parameters.
