Four, LCD display

First power on, off state

Boot state, display contents include: working mode, setting temperature, environmental temperature, communication address and fan status.

1) Working mode: two control products are available2Mode: heating and cooling; users can set it by mode keys. When the factory is out, the working mode is cooling mode.

2) Setting temperature: setting range is+5The temperature can be adjusted by increasing the temperature and lowering the temperature at the temperature range from +35 to C. When the factory is set, the temperature is 22 degrees centigrade. Step 1

3) Room temperature, the display temperature is 0 HI ~+95, when the room temperature is less than 5 degrees, showing LO; when room temperature is greater than 95 degrees, display the temperature.

4) Mailing address,Setting range is0000~FFFFIt can be adjusted by the expert mode key, and the user can modify it at will!

5) Fan status, including automatic identification and fan speed, can be set by fan keys. At the factory, the fan speed is high.

Automatic wind speed

Cooling state: when room temperature-Setting temperature >2 DEG C: valve opening, running high speed wind;

When room temperature-setting temperature1℃、2Temperature: the valve opens, runs medium speed wind

When room temperature-Setting temperature <1 DEG C: valve opening, running low speed wind

When room temperature-setting temperature>1 temperature: valve shut off, fan delay stop (fan controlled)

Heating state: Contrary to refrigeration

Six. Installation instructions

6.1 Be sure to install the device after power failure, otherwise it will damage the system components easily.

6.2 Select the correct installation position (about height from the ground)1.6Don't install the product in direct sunlight or moist position.

6.3 Altitude: no more than2000M.

6.4 If you install it in the toilet, please use a special waterproof mask.

6.5 According to the wiring diagram, according to the needs of the power board485Twisted pairABThe wire, the zero line, the electric valve and the fan coil are all connected correctly.

6.6 The power supply board and liquid crystal board is opened, screw the power board of the shell is fixed on the embedded cassette box. Pay special attention to the direction of the enclosure.

6.7 Clip the LCD panel into the open power panel.

6.8 After installation, electrify test.

Seven, product function overview

7.1 Valve status

 1Heating system

Two control, with three line control valve or three line two control valve - valve control width is +1When the room temperature is smaller than the set temperature1When the temperature is higher than the setting temperature, the valve is opened1At temperature, the valve is closed; others

In case, the valve maintains its original state.

Four control, with three lines and a control valve, cold water valve is in the closed state, the control width of hot water valve is +1C. When the room temperature is smaller than the set temperature1When the temperature is higher than the setting temperature, the hot water valve is opened1When hot, the hot water valve is closed; in other cases, the hot water valve maintains its original state.

2Refrigeration

Two control, with three line control valve or three line two control valve - valve control width is +1When the room temperature is greater than the set temperature1When the temperature is lower than the setting temperature, the valve is opened1At temperature, the valve is closed; in other cases, the valve maintains its original state.

Four control, with three lines and a control valve, hot water valve is in the closed state, the control width of cold water valve is +1C. When the room temperature is greater than the set temperature1When the temperature is above the set temperature, the cold water valve is opened1When the temperature is cold, the cold water valve is closed; in other cases, the cold water valve maintains its original state.

3After shutdown, the valve is turned off.

7.2 Fan status

The user can adjust the height, middle, low or automatic shift of the working gear through the fan key; in the automatic file, the product automatically adjusts the fan stalls according to the room temperature and the setting temperature.

Fan controlled: when the valve is closed20SAfter that, the fan is closed. Not controlled: the wind machine is working non-stop.

When the factory is out, the fan is controlled, that is, when the valve is closed20SAfter that, the fan is closed.

After shutdown, fan low air operation20SAfter closing.
