In order to use this product, please be aware of the details below.
Safety Precautions
Warnings
1. This product has not been manufactured as a safety device; therefore, in the
case that this product is going to be used for controls, such as devices from
which you feel concerned about personal injury, serious damage to the
peripheral devices and enormous property damage, please use it with double
safety devices attached.
2. Please do not connect, inspect or repair it when power is on.
3. The panel must be attached to use. It can be the cause of electric shock.
4. When connecting power, please be sure to identify the terminal number and
connect them.
5. Please never disassemble, process, improve or repair this device.
Caution
1. Prior to installation of this instrument, please well understand the safety
regulations, warnings and how to use and use this device only within its
specified relevant specifications or capacity.
2. Do not install or wire it on the motors and solenoids, etc. which are extremely
inductive loaded
3. When extending sensors, please use the same lines and do not make them
longer than necessary.
4. Do not use any parts which cause arc when directly opened or closed at the
same power or its nearby.
5. Please keep the power line away from the high-tension power cable, and do
not install it in a place where water, oil or dust is severe.
6. Please do not install it in the place of being exposed to direct sunlight or rain.
7. Please do not install it in the place of strong magnetism, noise, severe
vibration and shock.
8. Please keep it away from the place where strong alkaline and strong acidic
materials directly come out.
9. Do not spray water directly onto the device for the purpose of cleaning during
the installation in the kitchen
10. Do not install it in a location where the temperature /humidity exceed the
rated ones.
11. Please use it with the sensor wire not being broken or scratched.
12. Use an independent pipe and keep the sensor wire away from the signal line,
power and load wires
13. Please note that the follow-up services are not available when arbitrarily
disassembling or modifying this product.
14. A display on the terminal connection diagram is a safety phrase of caution or
warning.

15. Do not use near devices causing strong high-frequency noise
(high-frequency welders, high-frequency sewing machines, high-frequency
radios, large SCR controller).
16. When using methods other than specified by the manufacturer, injury or
property damage may occur.
17. Please keep out of children’s reach, since it is not a toy.
18. Please install it by the related professional or qualified person.
19. When wiring the product, terminals and screws should be tightened with
sufficient torque. Contact failure may cause a fire.
20. Do not use a load that surpassed the rated value of switching capacity of
relay contact point. This may cause insulation failure, contact weld, and
poor contact.
21. We disclaim all the responsibility for damages caused by the negligence
of the consumer or by not complying with a warning or caution statements
specified above.
Danger
Caution, danger of electric shock
1. Electric shock – Please do not touch the AC terminals while the power is
on. You may get an electric shock.
2. When checking the input power, please be sure to shut off the input power.

Special Feature
and Touch Function
With TET-LCD and touch, much information and colors can be
displayed and easy operation and recognition support a user-oriented
interface.
※ The product uses a capacitive touch method and thus requires
precautions as the key may cause malfunction if touched with wet
hands or used with thick gloves.
Central Monitoring Control Function
The product is embedded with the RS485 communication function to
be connected to a computer. It uses the Modbus protocol to be used
with the MMI (Man Machine Interface) system.
Alarm history store
Up to 20 alarm histories can be stored, which helps to analyze the
cause of problems and maintenance.
Compact and Slim
The integrated display and control ensure sufficient space.
Preheating and freeze protection
The function to prevent a breakdown of water pipes and equipment
due to water frozen in the cold weather.

Temperature Deviation
A regular interval is required between ON and OFF in the ON/OFF control
(set up ON/OFF width)
Frequent ON and OFF will shorten the lifespan of the relay or the output
contact or cause hunting (generation, chattering) by noise from outside.
The temperature deviation function is used to setup temperature deviation
to protect the equipment contact, etc.
Temperature Control Example

Setting Temperature 5.0℃, Temperature Deviation: 1.0℃

Sensor Calibration
While there is no problem in the product, if the temperature shown in the
display window and the actual temperature are differed, the function calibrates
the current temperature and adjusts to the actual temperature.
E.g.) Actual Temperature: 20.0℃ / Display Temperature: at 25.0℃
If the sensor calibration value is set at -5.0, the current temperature is
displayed at 20.0℃.

Stop Delay
When stopping the system, all the outputs except the pump are turned OFF,
only the pump output is maintained for the delay time, and OFF.
If the compressor is turned OFF when it is in operation, cold water may freeze
cold water and piping caused by cold air, so cycle pump as much as delay
time and all outputs OFF.

Before operation, the system is pre-heated as much as the set temperature
The function turns ON the heater output when the temperature is lower by
1.0℃ that the set temperature and when the system reaches the set
temperature, the function turns OFF the heater output.
The function is applied when the pump operation mode is in the manual mode.
Point for output ON
Pre-heat Operation: 4.0℃
Current Temperature < Setting Temperature - 1.0 (℃) → Output ON
Current Temperature ≥ Setting Temperature → Output OFF

E.g.) Suppose stop delay time is 60 seconds, the system is turned OFF at ,
and the output of the SV/COMP in operation will be turned OFF.
And the system will be delayed until the time (60 seconds) of and the
pump relay will be turned OFF.
Pre-heat Operation (Pump Automatic Mode)
Before operation, the system is pre-heated as much as the set temperature
The function turns ON the heater output when the temperature is lower by
1.0℃ that the set temperature and when the system reaches the set
temperature, the function turns OFF the heater output.
The function is applied when the pump operation mode is in the manual mode.
