220V/110V AC fan/motor Intelligent temperature control and voltage regulator
Product model: JAF22012
This governor is suitable for AC 220V/110V 50Hz&60Hz fan motors. The governor can control the voltage of the fan according to the monitored temperature, so as to realize the speed control of the fan/motor
When the temperature is lower than the set starting temperature value, the governor controls the fan to stop or maintain a low speed,
When the temperature is higher than the set full speed temperature, the fan runs at full speed,
When the temperature is between the start-up temperature and the full-speed temperature, the fan speed increases as the temperature increases, and slows down as the temperature decreases, so as to achieve the purpose of intelligent temperature control, energy saving, noise reduction and emission reduction.
In addition to fan speed regulation, this product can also achieve other extended applications based on temperature control AC voltage output.

3. Instructions for use of buttons
The panel has 4 buttons to display the temperature in real time. Through the buttons, you can set the fan`s starting temperature, full speed temperature, alarm temperature, working mode and other parameters
3.1 Set the start and full speed temperature of the fan
In the standby state, the panel displays the current temperature value, press the MODE button once, the digital tube displays L30, L represents the start temperature, and 30 represents the temperature value. Press the up and down keys to adjust the start temperature value. After the adjustment is completed, press the ok key to confirm.
In the standby state, the panel displays the current temperature value, press the MODE button twice, the digital tube displays H50, H represents the full speed temperature, 50 represents the temperature value, press the up and down keys to adjust the full speed temperature value, after the adjustment is completed, press the ok key to confirm
*After the temperature setting is completed, the governor will automatically control the fan speed according to the newly set temperature parameters.

3.2 Set the working mode of the governor
The governor supports two working modes, one is the shutdown mode and the other is the minimum speed mode;
In shutdown mode, when the actual temperature is less than or equal to the set start temperature L-2°C, the governor will control the fan to stop;
In the minimum speed mode, when the actual temperature is lower than the set starting temperature, the governor will control the fan to keep the minimum speed without shutting down the fan.
In the standby state, press the MODE button 3 times, and the digital tube displays P01. At this time, press the up and down buttons to adjust the working mode of the motherboard. P00 represents the shutdown mode, P01 represents the minimum speed mode, press the OK button to confirm
3.3 Set the temperature alarm value:
In the standby state, press the MODE button 4 times, and the digital tube displays b60. At this time, press the up and down keys to adjust the temperature alarm value. The default b60 means that when the temperature is higher than 60°C, the on-board relay is activated.
This function can be included in the PLC or industrial computer to prompt the temperature warning, or it can be directly used to drive the AC contactor to control other high-power cooling equipment
*Relay parameters: maximum withstand voltage 250V, maximum current 3A

3.4 Set the minimum speed of the fan (set the minimum output voltage of the governor)
In the standby state, press the MODE button 5 times, the digital tube displays Exx, xx represents the set minimum output voltage gear (not the voltage value), the factory default is 55,
*The minimum starting voltage for fans of different manufacturers is different. Some require very high voltage, and some are relatively low. In actual use, if you find that the governor cannot start the fan normally, you can increase the value of this parameter.
Four. Instructions for use
1. Connect the power supply of the governor and the wiring of the fan according to the interface instructions
2. Plug the temperature probe into the governor and fix the metal part of the probe on the heating part
3. Turn on the power, the governor will adjust the fan speed according to the temperature detected by the temperature probe
4. Pay attention to check whether the wiring is correct during installation
*Take the factory default temperature range of the governor as an example, the factory default temperature range of the governor is L=30¡É, H=50¡É, when the current temperature is greater than or equal to 30¡É,
The speed governor adjusts the fan speed in a linear proportion. As the temperature rises, the fan speed will also increase. When the temperature is greater than 50°C, the fan becomes full speed.
When the temperature drops to 28°C (L-2), the governor turns off the fan
*The power supply voltage of the governor must be the same as the rated voltage of the fan. How many volts the fan is, the power supply must use how many volts!
* When multiple fans are connected, the voltage of the fans connected to the governor must be the same, not one 220V, one 110V
