How to reset the alarm of the Meiyi MWH water source heat pump

Summary. Hello, I'm glad to answer for you, Meiyi water source heat pump failure**Daquan E1: compressor high pressure protection 1 There is an obstacle in front of the condenser.

2 Start cooling when the outdoor ambient temperature is higher than 43 degrees. 3. The control loop is abnormal. 4. The pressure of the high-pressure pipe is over-pressurized, and the high-pressure switch is activated.

E2: Evaporator anti-freezing protection 1 The indoor fan does not rotate or the tuyere is blocked. 2 The indoor ambient temperature is lower than 18 degrees.

3. The temperature sensing head of the tube is broken. 4. The plug of the thermometer plug is not plugged in properly. 5. The control loop is abnormal.

Hello, I'm glad to answer for you, the beauty of the difference between the bright and the water source heat pump failure**Daquan e1: compression of the high pressure protection of the wide machine 1 There is an obstacle in front of the condenser. 2 Start cooling when the outdoor ambient temperature is higher than 43 degrees.

3. The control loop is abnormal. 4. The high-pressure pipe Qingqiao presses over the high-voltage switch action. e2：

Evaporator anti-freezing protection 1 The indoor fan does not rotate or the tuyere is blocked. 2 The indoor ambient temperature is lower than 18 degrees. 3. The temperature sensing head of the tube is broken.

4. The plug of the thermometer plug is not plugged in properly. 5. The control loop is abnormal.

Pro, water source heat pump is the use of shallow high-altitude water sources on the earth's surface, such as groundwater, rivers and lakes to absorb solar energy and geothermal energy and form low-grade thermal energy resources, using the principle of heat pump, through a small amount of blind high-level electric energy stove old input, to achieve a technology of low-level thermal energy transfer to high-level thermal energy.

Meiyi water-type water source heat pump failure** The whole list is: E1: compressor high pressure protection 1 There is an obstacle in front of the condenser.

2 Start cooling when the outdoor ambient temperature is higher than 43 degrees. 3. The control loop is abnormal. 4. The pressure of the high-pressure pipe is over-pressurized, and the high-pressure switch is activated.

E2: Anti-freezing protection of evaporation trail trap 1 The indoor fan does not rotate or the tuyere is blocked. 2 The indoor ambient temperature is lower than 18 degrees.

3. The tube is broken off by the temperature sensitive. 4. The plug of the thermometer plug is not plugged in properly. 5. The control loop is abnormal.

E3: Compressor low pressure protection 1 Insufficient refrigerant. 2. The expansion valve is half-blocked, and the solenoid valve is balanced and rolled.

3 Filter half block. E4: Compressor exhaust temperature is too high to protect 1 system blockage.

2 Compressor aging. 3 The heat dissipation of the external unit is not good.

Hello! Glad for your question. Meiyi water machine failure**Daquan e9:

The water purification machine shows E9 fault**, which is generally a water production overtime fault, usually this kind of fault** indicates that the water speed of the water purification mechanism cannot keep up with the speed**, or the direct drinking machine cannot fill the bile level for 12 consecutive hours. Investigation method: bury shirt 1, check whether there is water in the water source and whether the water pressure is within the normal range; 2. Whether the RO membrane is blocked; whether the pre-PP and carbon rods are blocked; 3. Whether the water inlet solenoid valve is working normally, the pressure is insufficient, and whether it is damaged; 4. Whether the booster pump is working normally; 5. Whether the high-pressure switch and the check bending valve are working normally; You can check the above 5 points in turn, you can find out the problem, and then replace the accessories according to the problem;
