There is a difference between a solar thermostatic controller and distinctive standard household thermostatic controller.There are two sensor areas in the solar thermostatic controller, used to increase and activate a pump and obtain and accumulate heat.This kind of controller we commonly known such as differential thermostat.
Bar Graph
The bar graph indicator is used to examine clearly the fluctuation of temperature in both comptrollers and accumulator probe.The controller is used to activate the pump and obtain energy for consumption. There is a temperature difference between controller and stored heat or energy. A controller is based on this process.
The differential arrangement and its adjustment has been wholly and entirely assembled into one differential potentiometer adjustment.
