1. Water Flow Switch Protection
When the water inlet volume is low,the unit stops to protect the system.When the water volume recovers,the unit starts working again.
2. High/Low Pressure Protection
2. High/Low Pressure Protection
High/Low pressure switches will switch off the heat pump automatically to protect the whole system when the pressure is over high/low.
3. High Discharging Temperature Protection
3. High Discharging Temperature Protection
When the compressor discharging temperature is higher than 110℃，the unit will not work until the temperature is lower than 85℃.
4. Antifreezing Protection
4. Antifreezing Protection
When the unit is standby and water inlet temperature is lower than 4℃ but higher than 2℃ ,the water pump starts up to protect the system.
5. Compressor Overload Protection
5. Compressor Overload Protection
When the compressor is working overload,the unit will stop working to protect the whole System.

FAQ
Q: Where is your factory located?
A: Our company is located in Huadu District, Guangzhou City, Guangdong Province, China.
Q: Air to water heat pump is heating faster?
A:Air to water heat pump heating rate according to the water temperature and outdoor temperature. Summer inlet water temperature and outdoor temperature are high,so heating faster. In winter inlet water and outdoor temperature are lower so the heating is slow.
Q: How much the air to water heat pump power consumption?
A: Mainly influenced by outdoor temperature. When the outdoor temperature is lower, the heating time is longer,the power consumption is more,and vice versa.
Q: What are the benefits of heat pump?
A: There are five main benefits of dual system, safety, long lifespan, low maintenance and eco-friendly.
Q: Can it be used if it rains?
A: The air to water heat pump only influence of the outdoor temperature and inlet water temperature, not affected by rain.This is the most obvious advantages compared with the solar energy heater.
