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. EDT is the menu-editing parameter. Select tE menu for temperature

control settings; select Hu menu is for humidity control settings, and select

SYS is for system settings. Note: SYS menu is only available to TH220-W,

TH220A, and TH220A-W model.

Note 7. C-F is the parameter to set the temperature unit: C is for Celsius, and

F is for Fahrenheit.

Note 8. The parameter HdM sets the mode for delaying or constraint the

humidity output. It has three available modes, which are listed and explained in

the table below.

Table 2. Humidity output delay mode.

Details

No delay

Default value. No delay or constraint on the

humidity output.

Time-delay

Delay the humidity output by a timer set by HdT.

Temperature-

Allow humidity output only when the temperature is

range

within a range defined by parameter HoS and

HoD.

In situations such as controlling a curing chamber converted from a fridge,

there is usually a big decrease in the relative humidity (RH%) whenever the

compressor of the fridge is working. Also, there can be big increase in the

relative humidity when the user opens the door of the fridge. This kind of

change in RH% can gradually recover. However, if the controller's humidity

control kicks in right away, it creates in a big swing in the RH%.

Using time-delay (HdM = 1) or temperature-range constraint (HdM = 2) can

help users to reduce the RH% swing.

Note 9. The parameter HdT sets the delay timer for humidity output, it can be

set from 0 to 999 minutes. When HdM is set to "1", the output to the humidity

control will be delayed for a time period set by HdT.

Please note, the HdT is effective in both humidifying and dehumidifying mode.

In dehumidifying mode, the actual delay time of the humidity output is decided

either by either HAS or HdF, whichever is longer.

Note 10. The parameter HoS and Hob set up a temperature range within

which the humidity output is enabled. HoS defines a temperature setpoint for

enabling humidity output, i.e., a lower boundary; and Hob defines the

temperature band. Please see the diagram in Figure 6 for how these two

parameters affect the humidity output.

For example, when HdM = 2, HoS = 36°F, and HoB = 2°F, that means when

the temperature is below 36°F or above 38°F the humidity output won't be

activated even when the controller calls for output to the humidity channel.

Note 11. PSD is the Device Access Password (only available to TH220-W and

TH220A-W model). This parameter is used to lock the access to parameter

settings on AuberSmart app.

Note 12. RST is the reset parameter. Choose "n" to take no action. Chose "y"

to reset all parameters back to factory settings.

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 7, a) and the notch on the female connector (Figure 7, 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 8.
