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.

2. Specifications

Temperature Control Range - 40°C ~ 80°C, - 40°F ~ 176°F

Temperature Accuracy 0.5°C Temperature Control Mode On/Off Control. Heating or Cooling Temperature Control Output 15 A, 120 V or 240 V AC * Humidity Control Range 0 ~ 99.9% RH Humidity Resolution 0.1% RH Humidity Accuracy 4% RH

Humidity Control Mode

Humidity Control Output 15 A, 120 V or 240 V AC * Operating Temperature 0°C ~ 50°C Dimension 91 x 140 x 46 mm Input Power 85 ~242 V AC, 50 Hz / 60 Hz Sensor Cable Length 6 ft (2 m) Power Cable Length 3 ft (1 m)

* Please note: Although both temperature and humidity output can handle up to 15A, the combined total power of the two channels are limited to 15A due to the limitation of input power cord.

Measured temperature window: In normal operating mode, this window shows measured temperature. In parameter setting mode, this window shows parameter name. Measured humidity window: In normal operating mode, this window shows measured humidity. In parameter setting mode, this window shows parameter value. Alarm indicator: When the alarm is muted, the alarm indicator (the small dot on the last digit) will be on.

SET key: Access the program settings and parameter settings. UP key (Unmute): Increase the value. Press down momentarily to unmute the

alarm. DOWN key (Mute): Decrease the value. Press down momentarily to mute the alarm.

Temperature socket: Supply power to heater/cooler. Temperature indicator: Red LED indicator; it is on when the temperature

socket is energized.

Humidity socket: Supply power to the humidifier/dehumidifier. Humidity indicator: Green LED indicator; it is on when the humidity socket is

energized.

4. 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 temperaturecontrol 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.

The user should decide the appropriate configuration for each output socket based on the user’s particular application. Please refer to section 4.5 and second 5 for details.

4.4 Change the Setpoints The setpoint for temperature is TSP (TSP) and the setpoint for humidity is HSP (HSP). To access the setpoints, simply short-press the SET key, and

then the top window will show TSP and the bottom window will show its value. Use UP or DOWN arrow keys to adjust the value, and short-press the SET key again to save the new value and go to the HSP setting. The way to adjust and save the setting is the same as for temperature setpoint. Once you press the SET key again, the controller will return to its normal operation mode. Please see Figure 2 for how to access the setpoints.

4.5 Adjust Parameters

Other control parameters are grouped into three sub-menus: temperature (tE), humidity (Hu), and system (SYS)*. To access these parameters, longpress SET key for 3 seconds, the top window will show EDT (EDT). Then use UP or DOWN arrow key to select the sub-menu item (tE, Hu, or SYS) in the bottom window, then press SET key again to confirm the selection. Please see Figure 3 for how to access these parameters. The details for each parameter are explained in section 5.

5. Parameter Settings

All parameters are listed in Table 1. When a parameter is displayed in the top window, its value is displayed in the bottom window. The user can use the UP or DOWN arrow key to adjust the value in the bottom window, then press the SEK key to save the new value and go to the next parameter. If no key is pressed for 10 seconds, the controller will exit to its normal operating mode.
