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.
HdM Mode
Details
0
No delay
Default value. No delay or constraint on the
humidity output.
1
Time-delay
Delay the humidity output by a timer set by
HdT
.
2 Temperature-
range
Allow humidity output only when the temperature is
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.

Figure 6. When the humidity output delay mode is
HdM
= 2, the humidity
output is allowed only when the temperature is within the range set by
HoS

HoD

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.
