TH220A TEMPERATURE AND HUMIDITY CONTROLLER
INSTRUCTION MANUAL
Version 1.3 (May, 2019)
1.
Overview
This plug-n-play temperature and humidity controller is designed for high
relative humidity (>85%) and condensing environments, where slight
temperature drop may cause condensation and could damage the sensor. This
controller equipped with one of the most robust humidity sensors on the
market. It can be fully recovered even immersed in water. Ideal for curing
Fridge. The controller can control both temperature (heating or cooling) and
humidity (humidifying or dehumidifying) at the same time.

Getting Started
4.1 Power up the controller and connect the sensor
To power up the controller, simply plug its power plug to a wall outlet. Then
connect the 4-pin connector from the humidity sensor to the sensor input port
on the bottom of the controller. Please align the notch on the sensor plug with
the key on the sensor socket. You can refer to the Section 6 in the manual for
details.
4.2 Displayed Information
The top LED window displays the measured temperature, and the bottom LED
window displays the relative humidity reading. If sensor is not connected or
defective, the controller will show “
ERR
” in its display window.
There is one LED indicator on each side of the controller to show the output
status of each output socket. The red LED on the left is for the temperature-
control socket, and the green LED on the right is for the humidity-control
socket.
4.3 Decide the Control Mode for Each Output Socket
The temperature-control socket can be set either to drive a heating device or to
drive a cooling device. This temperature-control mode is determined by the
parameter
tCM
(
tCM
), which can be set to “
Ht
” for heating, or “
CL
” for
cooling.
Similarly, the humidity-control socket can be set either to drive a humidifying
device or to drive a dehumidifying device. This humidity-control mode is
determined by the parameter
hCM
(
hCM
), which can be set to “
H
” for
humidifying, or “
DeH
” for dehumidifying.
