Instruction Manual
Manual Mode
•
MANUAL MODE
allows you to keep your fan at a constant speed
level, regardless of the current room temperature
•
MANUAL MODE
is indicated with the
HAND
icon in the top
centre
section of the screen
•
To select your desired speed level, press the
UP
or
DOWN
arrow
buttons on the controller
•
You can select between 6 speed levels, which correspond to the
following percentages from the maximum fan motor output:
- Level 0 corresponds to the output of 0% from the max. speed
- Level 1 corresponds to the output of 15% from the max. speed
- Level 2 corresponds to the output of 32% from the max. speed
- Level 3 corresponds to the output of 50% from the max. speed
- Level 4 corresponds to the output of 67% from the max. speed
- Level 5 corresponds to the output of 83% from the max. speed
- Level 6 corresponds to the output of 100% from the max. speed
•
The selected speed level is indicated on the controller's screen by
the rotating impeller icon and the number between 0-6
.
•
AUTO MODE
allows the controller to automatically adjust the
speed of the connected fans to maintain your pre-determined target
temperature (based of the temperature reading of the
thermal probe).
•
To set up
AUTO MODE
, ensure that the
AUTO
icon is displayed in the
centre of the top row of the controller's screen. If you see the
HAND
icon instead, press and hold the
MODE
button for 3 seconds until the
icon switches to
AUTO
.
•
Use the
UP
and
DOWN
arrows to select the desired temperature.
This temperature represents the level that you want to maintain in
your ventilated space. The desired temperature can be selected from
0ºC (32ºF) up to 60ºC (140ºF).
Programmable Auto Mode
Auto Mode Baseline Speed
•
BASELINE (DEFAULT)
speed level is the speed level maintained
by the controller when your desired temperature has
been reached
•
Select the
BASELINE
speed level by pressing the
MODE
button
once again when
AUTO MODE
is already activated. The number
displayed under the spinning propeller icon will start blinking,
allowing you to select a value from 0 to 6.
•
In applications which require moving air even when your target
temperature is reached, we recommend the
BASELINE
speed be
set at level 1-3, so that the fan maintains low to medium airflow
while the temperature is already at your desired level
•
If your application requires the fan to be turned off when your
target temperature has been reached, the
BASELINE
speed must
be set at level 0. This effectively means that you want the fan to
be blowing only when the temperature in your ventilated space
exceeds your target level.
Auto Mode
Speed Adjustment Logic
•
When the room temperature increases over your desired level, the
controller will automatically accelerate the speed of all connected
fans to reduce the temperature to your desired level.
•
The fan's speed will increase by 1 additional speed level for every
2ºC/2ºF difference over your desired temperature level.
•
In the scenario when your desired temperature level selected for
AUTO MODE
is 30°C and your baseline speed level is 1. Once the
room temperature increases to 32°C, the fan's speed will increase to
level 2. If the temperature increases to 34°C, the fan's speed will
increase to level 3 and so on until the fan's speed reaches level 6 at
40°C or above.
•
The fan speed will decrease by 1 speed level for each 2ºC/2ºF
reduction in difference over your desired temperature level.
Temperature Alarm
•
TEMPERATURE ALARM
feature allows the user to select the
temperature level, which once reached, triggers the fan to
immediately accelerate to the maximum speed.
•
The fan will override the current speed setting and blow at
maximum speed until the temperature reduces below the
TEMPERATURE ALARM
level or unless the
TEMPERATURE
ALARM
is deactivated by the user.
