TD400P Programmable Temperature Controller
Version 1.1 (Oct, 2017)
1.
Overview
This is a dual-output temperature controller with 8 programmable steps. It
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.
The temperature control can be programmed to vary with different time step
setting. Up to 8 temperature-time steps covering 33 days can be programmed.
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 the 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 read out. 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.

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

Basic Operation
Here are the basic operating procedures to use this controller. To fully
understand the functions on this controller, please read the entire manual.
1) Connect the temperature sensor to the sensor socket that is located on the
top of the controller. Please check the alignment of the slot on the plug with the
key on the socket. (See section 12 for details.)
2)
Plug the controller’s power cord to a wall outlet.
3) Set up the program and system parameters. Please read the rest of this
manual for details.
4) Connect the cooling device and/or heating devices to the output sockets on
this controller.
5) Press START key to start running the program.
