MSV
Multi Solar Valve & Pump Controller
The MSV is is designed to give you year round automatic control of pool systems where a solar heating system (solar pump, solar valve and solar heater panel) has been retro-fitted to a basic system of pool, filter and filter pump. It combines pump and valve control for solar heating.
When the unit turns the pump on it also closes the valve. This unit is used when the filter pump pushes water through the solar system.
