TH220 TEMPERATURE AND HUMIDITY CONTROLLER

INSTRUCTION MANUAL

Version 1.2 (Oct, 2017)

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.

4. Setup Flow Chart

When the controller is powered on, it will display the measured

temperature and humidity. The controller will keep running according to the

saved setting. If the humidity or temperature sensor is shorted/disconnect, the

controller will display “Err”. Please see Figure 2 and 3 for the flow chart to set

the parameters.

5. Parameter Settings

To change the target temperature or humidity, press SET key momentarily.

The controller will show tSP (temperature set point), press SET again will show

HSP (humidity set point). Use Up or Down key to change the tSP or HSP. See

Figure 2 for details.

To change the other parameters, press SET key for 3 seconds, the RH window

(bottom window) will show tE, Hu or SYS* (depending on which menu was set

last time). tE menu is for temperature control settings; Hu menu is for humidity

control settings and SYS* is for system settings. Press Down (or Up) key to

change the RH window to Hu (or tE, SYS), which is the current selected menu,

then press SET key to enter.

To change parameter settings, in the parameter setup mode, use Up or Down

key to modify the parameter value. Then press SET key again to confirm the

change. This instrument will automatically exit if no key is pressed for 10

seconds. Please see the Table 1 for the parameters.

* Menu SYS and parameter PSD are only applicable for TH220-W model.

Note 1. For heating (or humidifying), the output will be off when the

temperature (or humidity) reaches the set point; it will be on again when the

temperature (or humidity) drops down to tSP - tdF (or HSP - HdF).

For cooling (or dehumidifying), the output will be off when the temperature (or

humidity) reaches the set point; it will be on again when the temperature (or

humidity) rises to tSP + tdF (or HSP + HdF).

Small differential gives tight control. Large differential reduces the frequency of

cycle on and off, and it will extend the life of relay and compressor.

Note 2. The offset is used to set an input offset to compensate the error

produced by the sensor or input signal itself.

For example, for temperature reading, if the unit displays 37 ºF when the actual

temperature is 32ºF, setting parameter toF = - 5 will make the controller display

32ºF.

Note 3. The low limit alarm will be always lower than the high limit alarm. When

the measured temperature (humidity) is higher than tAH (HAH), the

temperature (humidity) high limit alarm will be on; when the measured

temperature (humidity) is lower than tAL (HAL), the temperature (humidity) 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.

When the alarm is muted, the alarm indicator (see Figure 1, the small dot on

the last digit) will be on. If the measured value gets out of the alarm zone then

AUBER INSTRUMENTS WWW.AUBERINS.COM

2017.10 P3/3

gets back to the alarm zone again, the alarm will be on again. To resume the

alarm, press the Up key, the alarm indicator will be off.

To disable the alarm, set High Limit Alarm = Low Limit Alarm.

Note 4. When The controller is used for cooling (or dehumidifying control) and

load is a compressor, it should not turn on the compressor when it is at high

pressure (just after turned off). Otherwise, it may shorten the life of

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 output

contact remains open (after reaching cutout) before closing again. The delay

overrides any load demand and does not allow the output contact to close until

the set time-delay value has elapsed. It gives time to release the refrigerant

pressure through evaporator. It is typically set to 4-6 (minutes).

Note 5. The TSF (HSF) can be set to ON or OFF. When it is set to ON, the

output will always be on when the sensor fails; when it is set to OFF, the output

will always be off when the sensor fails.

For example, when the unit controls a refrigerator for food, you may want to set

the TSF to ON if the sensor fails to keep the food cold. When it controls a

heater, you may want to set the TSF to OFF for safety purpose.

Note 6. Menu selection parameter. tE menu is for temperature control settings;

Hu menu is for humidity control settings and SYS is for system settings. SYS

setting is only available to TH220-W model.

Note 7. Device access password (only available to TH220-W model). This

parameter is used to lock the access to parameter settings on AuberSmart

app. Please refer to figure 3.

6. How to install the sensor to the unit.

The connector of sensor contains a slot for fitting pin connection. It locates at

the bottom of the controller. It also has a spring lock to prevent disconnections

from accidental pulling on the cable.

To install the sensor to the controller: 1) Identify the key on the male sensor

connector (Figure 4, a) and the notch on the female connector (Figure 4, b). 2)

Hold the tail of the female connector, align the notch and the key, and push the

female connector forward.

To remove the connector, hold the spring-loaded collar on the female

connector and pull it back. Please see Figure 5.
