This is the original instruction, please read all manual instructions carefully before operating. VEVOR reserves a clear interpretation of our user manual. The appearance of the product shall be subject to the product you received. Please forgive us that we won’t inform you again if there are any technology or software updates on our product.

Warning- To reduce the risk of injury, user must read instructions manual carefully.

WARN

1. PLEASE MAKE SURE THAT THE POWER SUPPLY AND THE POWER OUTLET ARE IN GOOD CONTACT AND THE GROUNDING WIRE MUST BE FIRM!
   Although the average working current of the chiller is small, the instantaneous working current can sometimes reach 6~10 amperes (the instantaneous working current of the AC110V power supply model is possible up to 10~1 5 amperes)

2. PLEASE MAKE SURE THAT THE WORKING CHILLER HAS A STABLE AND NORMAL VOLTAGE!
   Since the refrigeration compressor is more sensitive to power supply and voltage, so the working voltage our standard product is 220^ 240V (110V model is 110 120V), if you really need a wider operating voltage range, we can customize.

3. PLEASE MISMATCHED POWER FREQUENCY WILL CAUSE CHILLER DAMAGE!
   Please select mode: 50Hz or 60Hz depending on the actual situation.

4. TO PROTECT THE PUMP, IT IS STRICTLY FORBIDDEN TO RUN THE CHILLER WITHOUT WATER IN THE STORAGE TANK!
   The new machine is packed after draining the entire water in the tank, so please make sure that the tank has enough water and there is water inside the machine before starting, otherwise it is easy to damage the pump.
   When the water level is below the green (normal) range of the water level gauge, the cooling capacity of our chillers will drop slightly. Therefore, make sure that the water level is in the green (normal) range. Pumps are strictly forbidden by circulating drainage!

5. PLEASE MAKE SURE THE AIR INLET AND OUTLET ARE WELL VENTILATED!
   The air outlet from the obstacle to the back of the cooler must be at least 30 cm, and it should be at least 8 cm between the obstacle and the side air intake.

6. THE FILTER MUST BE CLEANED REGULARLY!
   The dust meter must be unlocked and cleaned, otherwise it will cause serious clogging failure to the cooler.

7. PAY ATTENTION TO THE EFFECT OF CONDENSATE!
   As the ambient humidity increases, when the water temperature is lower than the ambient temperature, condensate will create circular pipes and cooling parts on the water surface. If this occurs, it is recommended to set a higher water temperature or keep the connected pipes and cooling components warm.

PROFESSIONAL USE ONLY!
This device must not be used by a child or a person with physical, sensory or physical, sensory, or physical impairments, or lack of experience and knowledge, unless supervision or instruction is given, and the child is not allowed to play with electrical appliances!
The circulating water of the water cooler must use a sealed container for normal use, such as laser tube cooling water. Unsealed containers cannot circulate, such as water basins, buckets cannot be used for circulating water cooling with water coolers.

PROCEDURE

Installing this industrial chiller is very simple.
The first installation of a new machine can be carried out by following these steps:

| ①.OPEN THE PACKAGE TO CHECK IF THE MACHINE IS FIXED AND ALL NECESSARY ACCESSORIES ARE COMPLETE.
---|---
| ②.OPEN THE WATER SUPPLY INLET TO SUPPLY COOLING WATER (DON’T SPILL THE WATER OUT!).
Observe the water level gauge and add water slowly, taking care not to let the water overflow! For the cooling of carbon steel equipment, an appropriate amount of cooling water additive (anti-corrosion water aqua) should be added to the water. Users in cold regions should use non-corrosive antifreeze.
| ③.CONNECT THE INLET AND OUTLET PIPES  ACCORDING TO THE SYSTEM CONDITIONS.

④.PLUG IN THE POWER SUPPLY AND TURN ON THE POWER SWITCH. (DON’T START WITHOUT WATER IN THE TANK!)
(1) The power switch is turned on and the circulating pump of the chiller starts to work. The first operation may cause more bubbles in the pipe, causing occasional alarms for traffic, but after a few minutes of operation, it will return to normal.
(2) After the first start-up, the water pipe must be checked for leakage immediately.
(3) The power supply is turned on, if the water temperature is lower than the set value, it is normal that the fan and other parts of the machine do not work. The temperature controller will automatically control the working state of compressor solenoid valves, fans and other components according to the set control parameters.
(4) Since the restart of the compressor and other components takes a long time, depending on different conditions, the time varies from a few seconds to a few minutes, so do not turn off the power frequently and turn it on again.

| ⑤.CHECK THE WATER LEVEL IN THE TANK.
The first start of the new cooler drains the air in the water pipe, causing a slight drop in the water level, but in order to maintain the water level in the green area, it is allowed to add enough water again. Please observe and record the current water level, check again after the chiller has been running for a period of time, and if the water level drops significantly, please re- check the leakage of the water pipe.
---|---

⑥.ADJUST THE TEMPERATURE CONTROLLER PARAMETERS.
CW-5000/5200 series uses intelligent thermostats. Usually the user does not need to adjust it. If it is really necessary. See “Operating status and parameter tuning”.

CONTROLLER WIRING DIAGRAM

Note:
①. Strictly distinguish the wiring of power supply, relay output and sensor, and the relay should not be overloaded.
②. All wiring changes must be made with the power supply disconnected.
③. This controller is forbidden to be used in water or excessively humid environments, and is prohibited from being used in high temperatures, strong electromagnetic interference, and strong environments.
④. Ensure that the power supply voltage is consistent with the voltage marked on the controller, and ensure the stability of the power supply voltage;

CONTROL THE OUTPUT FUNCTION

1. REFRIGERATION CONTROL:

CHILLER WORKING CONDITION| COMPRESSOR CONDITION| REFRIGERANT SOLENOID VALVE WORKING CONDITION| HEATING ROD WORKING CONDITION| REMARK
---|---|---|---|---
refrigeration| running| **** end| Stop it| 100% full power refrigeration
One-stage micro refrigeration| running| Conduction| Stop it| 40% power refrigeration
Two-stage micro-cooling| running| Conduction| initiate| 20% power refrigeration heating rod work
heating| Stop it| Conduction| initiate| No refrigeration, only heating

The above are the four working states of the chiller controlled by the smart thermostat. The shortest transition time between refrigeration and micro- cooling is (about 5-10 seconds) and can be changed multiple times in one minute.
If the heat load is turned on, the chiller mainly works in these two working conditions, and the temperature of the cooling water can be precisely controlled. (The water temperature fluctuates around 0.3 degrees Celsius during the actual test.) When the heat load is turned off, the water temperature is overshooted downward, and when the A0 set value is reached, the refrigeration compressor stops working.
It is important to note that; There will be a time difference between the conversion of the chiller working condition and the change of water temperature, and the parameter A6 is the relevant parameter that describes the inertia of the system, according to this parameter, the controller can calculate the corresponding action advance, reduce the overshoot of the water temperature.

REFRIGERANT SOLENOID VALVE

1. When the compressor is working, when the temperature is reduced to (equal to, below) the set value of the water temperature, and the cut-off duration of the refrigerant solenoid valve has been greater than the time set by the state transition delay (A3), the refrigerant solenoid valve is turned on. When the temperature rises above (higher) the water temperature set value, and the conduction duration of the refrigerant solenoid valve is greater than the time set by the state transition delay (A3), the refrigerant solenoid valve is cut off.
2. When the compressor stops running, the refrigerant solenoid valve is turned on.
3. When the compressor starts to work (when starting), the refrigerant solenoid valve must be in the cut-off state (under normal circumstances, this condition is satisfied).

ELECTRIC HEATING RODS
When the water temperature is lowered below the water temperature set point – the electric heating rod controls the difference, the electric heating rod starts to work. When the water temperature rises to higher than the water temperature set value – the electric heating rod controls the difference, the electric heating rod stops working.

2. WATER TEMPERATURE SETPOINT:
When the thermostat is operating in constant temperature mode, the water temperature setting value is constant at F0 just like a normal thermostat. When the thermostat is in smart mode, the water temperature setting is varied.
SMART MODE SETPOINT
When the room temperature plus F1 is less than F9, the water temperature set value is equal to F9
When the room temperature plus F1 is greater than F8, the water temperature setting value is equal to F8
When the room temperature plus F1 is less than, equal to F8, greater than, or equal to F9, the water temperature setting value is equal to room temperature

• F1

3. ALARM CODE AND CONTROL LOGIC:

high alarm value (F6 setting value)
Er2| The water temperature is too high| Water temperature> set temperature + refrigeration difference F2 + water temperature super high alarm F4
Er3| The water temperature is too low| Water temperature< set temperature – heating return difference A0 – water temperature ultra-low alarm F5
Er4| Room temperature sensor failure| Room temperature sensors are short- circuited or open-circuited
Er5| The water temperature sensor is faulty| The water temperature sensor is short-circuited or open-circuited
Er6| External input alarms| The external connection is lost
Er2 and Er3 will only be effective when the water temperature enters the target temperature section (i.e., between the set temperature and the set temperature + refrigeration difference F2) after satisfying the start-up alarm delay (A1) or after powering on and forced cooling for 30 seconds

1. THE CONTROL STATE WHEN THE ALARM IS GENERATED
   When the Er3 alarm occurs, the refrigeration and heating relays operate according to normal logic.
   When the Er4 alarm occurs, the water temperature setting (F0) of the controller runs according to the factory setting. (If the controller works in constant temperature mode, E4 does not alarm)
   In the event of an Er5 alarm, the system should be shutdown regardless of the state in which it is running.

2. ALARM STOP SOUND
   In the alarm state of the thermostat, press any button to stop the alarm buzzer, but the alarm display will not stop until the alarm condition is eliminated.

3. EXTERNAL INPUT ALARM:
   After the external input alarm signal and the time of delay setting A9 is satisfied, Er6 is displayed, the system control is not affected, and the alarm buzzer sounds.

4. When Er1-Er6 appears, the alarm buzzer sounds, and when the silencer alarm key is pressed, the buzzer stops ringing. Alarm output, relay and other faults are automatically reset after they are removed.

5. When Er1-Er6 appears, the alarm buzzer sounds, and when the silencer alarm key is pressed, the buzzer stops ringing. Alarm output, relay and other faults are automatically reset after they are removed.

6. KEY TONE
   There is a key prompt when the controller button is pressed, and a short tone prompt when each button is pressed.

7. POWER-ON ID
   After powering on, the display flashes for 3 seconds, and the indicator light and digital tube are displayed at the same time, and the buzzer enters the normal logic operation state after the sound.

8. TEMPERATURE CORRECTION
   Room temperature calibration and water temperature calibration, when the displayed temperature (room temperature and water temperature) is deviated from the actual temperature, A4 and A5 can be adjusted for correction.

9. POWER-ON PROCESSING
   After the power-on delay (A2) time passes after the thermostat is powered on, the thermostat enters the 100% full-power cooling state for 25 seconds. Then control the chiller to work according to the actual air temperature and water temperature.
   (Note: This is the “Forced Refrigeration on Boot” function.) If the water temperature is higher than the water temperature setpoint-heating backdrop, the compressor does not need to stop after the forced refrigeration is turned on. This function is designed to facilitate maintenance work)
