Non-pressurized solar water heater controller m7 with high quality
solar water heater controller m7
A Solar thermal controller can be seen as the brains of a solar water heating system.
It control and regulates the transport of heat between the storage vessel (geyser) and the solar collector.
With the use of temperature sensors the controller knows what the temperatures are at different places
within the flow of the solar heating system. This enables the controller to allow or stop the circulation
between the solar collector and the storage vessel, giving you complete control over how the system will react.

<10> Solenoid Valve: DC12V for pressurized and non pressurized valves
<11> Pressurized working pressure: 0.02~0.8Mpa, for direct water supply
<12> Non pressurized: working pressure: 0 Mpa, for water supply and low pressure water supply
Do not flush directly the controller with water.Check if all connecting lines have sound connection.
1. To protect the solar water heater and water temperature & level sensor,the water tank
should not lack of water for a long time.
2. To prevent long overflow caused by accidental problems,such as error operation,
anomalous power supply and malfunction etc.the solenoid valve and the solar water
heater should be in stalled in a room without water leakage or in a place free of accidents
due to sprays.With a return pipe and take qualified lighting protection measures against thunderstroke.
While the power should be disconnected to stop the use of solar water heater for the safety of life.
