Full Automatic Solar Water Heater Controller for Compact and Split System

The Solar Controller  is both the heart and brains of a solar water heater. It is what controls the flow of heating fluids and water, based on programmable temperature differential measurements. It measures the temperature in various zones such as at the output of the collectors and compares this to the temperature of the solar storage tank and makes decision to turn off/on pumps and Diverter valves. The solar controller can display the current status of the system and make adjustments for safety. The digital controller will turn the pumps on when there is heat demand from the collector, divert the heat to an auxiliary heating system and shut the system down if the heat demand is too low (or too high in emergency conditions).We have three models: HLC-388: For compact pressurized solar water heater with timing and thermostat controlling for electric heater. HLC-588: For split pressurized solar water heater with temperature difference circulation, timing and thermostat control for electric heater.  HLC-288: For non-pressurized solar water heater, with water level sensor, water re-filling, timing and thermostat control for electirc heater.    /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
