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.

6. Parameter Settings

To change the target temperature (set points), press SET key
momentarily. The controller will show CSP (Cooling set point), press
SET again will show HSP (heating set point). When the controller
shows CSP or HSP, use Up or Down key to change the value. Then
press SET key to confirm the change. See figure 2 for details

To change the system parameters, press SET key for 5 seconds, the
controller will enter the parameter set up mode. The first parameter AH
will show on the display. Use Up or Down key to modify the parameter
value. Then press SET key to confirm the change. The display will
show the parameter again. Press the SET key to show the next
parameter. The instrument will automatically exit if no key is pressed
for 10 seconds. See figure 3 & table 1 for details.

Note 1. For cooling (or heating), the output will be off when the
temperature is below (or over) the set point; will be on again when the
temperature rises up (or drops down) to CSP + CdF (or HSP - HdF).

The maximum value of the HSP can be set is the current value of CSP.
But CSP can be set to the value between -58 ~ 248ºF or -50 ~ 125ºC.
When the CSP is set to a value lower than current HSP, the HSP will
be adjusted to the CSP value automatically.

For example, when CSP = 67.0ºF, HSP = 62ºF, HSP can be set to any
value between -58ºF and 67.0ºF. For CSP, it can still be set to any
value between -58º F and 248ºF. If you set it to 55.0, the HSP will be
adjusted to 55.0ºF automatically.

Small differential gives tight control; large differential reduces the
frequency of cycle on and off. It will extend the life of relay and
compressor.

Note 2. When the measured temperature is higher than AH, the high
limit alarm will be on; when the measured temperature is lower than AL,
the low limit alarm will be on.

When alarm is on, the display will be flashing between the measured
value and alarm type. To mute the alarm when it is on, press the Down
key momentarily. If the measured value gets out of the alarm zone then
gets back to the alarm zone again, the alarm will be on again. To
disable the alarm, set AH the same value as AL (AH = AL).

The maximum value of the AL can be set is the current value of AH.
But AH can be set to the value between -58 ~ 248ºF or -50 ~ 125ºC.
When AH is set to a value lower than current AL, the AL will be
adjusted to the AH value automatically.

For example, when AH = 95.0ºF, AL = 32º F, AL can be set to any value
between -58º F and 95.0ºF. For AH, it can be set to any value between

-58ºF and 248ºF. If you set it to 25.0ºF, the AL will be adjusted to

25.0ºF automatically.

Note 3. The Cooling Anti-short is the delay time to turn the cooling load
on. When the controller is used for cooling and load is a compressor, it
should not turn on the compressor when it is at high pressure (just right

after it turned off). Otherwise, it may shorten the life of the compressor.
The Anti-short cycle delay function can be used to prevent the rapid
cycling of the compressor. It establishes the minimum time that the NO
