④ Button (Key) Description:
1. RST: A) To turn the controller On and Off: To turn the controller ON press the RST key. To turn the controller OFF press and
hold the RST key for 3 seconds.
B) To set the Heating Temperature (lower set point): Press the RST key once and the controller will go to the “heating
temperature setting or lower set point setting” mode. By pressing ▲ or ▼ keys you can adjust the temperature to your
required set point. When the lower set point is adjusted you can exit the “heating temperature setting” mode by pressing
the RST key again (or wait for about 15 seconds and the controller automatically exit this mode). This lower set point
can also be set via F2 parameter (learn more about this in parameters setting section).
2. SET: A) To set the Cooling Temperature (higher set point): Press the SET key once and the controller will go to the “cooling
temperature setting or higher set point setting” mode. By pressing ▲ or ▼ keys you can adjust the temperature to your
required set point. When the higher set point is adjusted you can exit the “cooling temperature setting” mode by
pressing the SET key again (or wait for about 15 seconds and the controller automatically exit this mode). This high
set point can also be set via F3 parameter (learn more about this in the parameters setting section).
B) To set the controller parameters: Press and hold the SET key for more than 3 seconds and the controller will go to
the “parameter setting menu”. By pressing ▲ or▼ keys you can select the required parameter from the menu. When the
required parameter is found, press the SET key once and the controller will go to the required parameter setting mode.
By pressing ▲ or ▼ keys, you can adjust the parameter that you need. When the parameter is set, you can exit the
“parameter setting mode” by pressing the RST key (or wait for about 15 seconds and the controller automatically exit
this mode).
3. ▲: Increasing key
4. ▼: Decreasing key
⑤ Operating Instructions:
LED Status (light display):
- When the red light beside the “Work” is ON it shows that the output (heating or cooling) is working.
- If the light beside the “Work” flashes, it shows that the controller is on delay.
- If the light beside the “Set” is ON, it shows that the controller is on setting mode.
◆ Heating and cooling functions:
- If the current temperature is more than the cooling temperature (higher) set point [≥( F3 + F1)], the cooling output relay will
be opened and will turn the chiller (the cooling source) ON and when the current temperature drops to lower than the cooling set
point [≥ (F3-F1)] the cooling output relay will be closed and will turn the cooling source OFF.
- If the current temperature is less than the heating temperature (lower) set point [≥( F2 – F0)] , the heating output relay will
be opened and will turn the heater ( the heating source ) ON and when the current temperature passes the heating set point
[≥ (F2+F0)] the heating output relay will be closed and will turn the heating source OFF.
◆ Heating and cooling temperature (Lower and Higher set points) settings (“F2” and “F3” parameters):
To set the Heating and Cooling temperatures, press and hold the "SET" key for more than 3 seconds to enter the “parameter
setting menu”. Find the “F2” or “F3” parameters by pressing ▲ or▼ keys. Press the "SET" key when you find the “F2” or “F3” and
then by pressing "▲" or " ▼ " adjust the temperature. “F2” parameter is for heating temperature (lower set point) and “F3”is for
cooling temperature (higher set point).
◆Hysteresis or Differential Set Value (Temperature Band) function:
To prevent the frequent ON/OFF action of the output, a temperature band (called hysteresis or differential set value) is created
between the ON and OFF operations. The controller will use a range (a maximum and minimum) for process control action, which
is between 1℉ to 30 ℉. For example when the cooling hysteresis (F1) is set on 5 and the higher set point (F3) is on 50 ℉, and
when the heating hysteresis (F0) is set on 3 and t the lower set point (F2) on 20 ℉, the ON/OFF action of heating output would be
when the temperature goes lower than 17 ℉ and the cooling output would be when the temperature goes higher than 55 ℉.
◆ Hysteresis (heating and cooling hysteresis) settings (“F0” and “F1” parameters):
Press and hold the “SET” key for more than 3 seconds to enter the “parameter setting menu”. Find the “F0” or “F1” parameters by
pressing "▲" or "▼" keys. Press the “SET” key when you find “F0” or “F1” and then by pressing "▲" or "▼" adjust them to any
number from 1 to 30 . “F0” parameter is for heating hysteresis and “F1”is for cooling hysteresis.
◆ Temperature calibration:
You can calibrate the temperature reading with this function. Correction value can be positive, negative or 0.
◆Temperature calibration setting (“F4” parameter):
Press and hold the “SET” key for more than 3 seconds to enter the “parameter setting menu”. Find the “F4” parameter by pressing
"▲" or " ▼" keys. Press the “SET” key when you find “F4” and then by pressing "▲" or "▼" adjust this parameter.
◆ Delay Protection:
In the cooling mode, you can use this parameter to set the controller on the state of compressor boot delay protection. It
prevents breaking the compressor as a result of frequent boot . It also protects the compressor in the state of power cut and then
power on. You can define the delay time for starting of your cooling machine.
◆ Delay setting (“F5” parameter):
Press and hold the “SET” key for more than 3 seconds to enter the “parameter setting menu”. Find the “F5” parameter by pressing
"▲" or "▼" keys. Press the “SET” key when you find “F5” and then by pressing "▲" or "▼" adjust this parameter.
◆ High and low temperature alarm functions:
- If the temperature exceeds the higher alarm temperature “F7” the alarm output relay will be opened, the controller makes
beeping sound and the display will alternately flash between ”H” and the current temperature. By pressing any key the buzzer
alarm will stop and alarm relay output will be closed.
- If the temperature drops to lower than the lower alarm temperature “F6” the alarm output relay will be opened, the controller
makes beeping sound and the display will alternately flash between ”L” and the current temperature. By pressing any key the
buzzer alarm will stop and alarm relay output will be closed.
◆ High and low temperature alarm settings (“F6” and “F7” parameters):
Press and hold the “SET” key for more than 3 seconds to enter the “parameter setting menu”. Find the “F6” or “F7” parameters by
pressing "▲" or "▼" keys. Press the “SET” key when you find “F6” or “F7” and then by pressing "▲" or "▼" adjust the
temperature. “F6” parameter is for lower temperature alarm and “F7”is for higher temperature alarm.

⑥Error messages and troubleshooting:
1) When the controller displays --- it shows that the sensor is disconnected. The controller will make beeping sound and the
heating output relay will be closed (so the heater is off) .
2) When the controller displays LLL it shows that the measured temperature by sensor is lower than -58 ℉.
3) When the controller displays HHH it shows that the measured temperature by sensor is higher than 230 ℉.
⑦ Caution :
◆ The maximum current load of the heating or cooling source must not exceed the output relay contact capacity. It will
damage the unit and may cause fire.
◆ Check the wiring diagram before wiring the unit. Wrong wiring will damage the controller and may cause fire.
◆ Applying extra force on the screws of controller terminals will break the base. Please tighten the screws gently.
◆ Turn the power supply off when you are wiring relays, sensors, ..Otherwise it will damage the unit and may cause fire.
