Product Details
D-315 provides intelligent control of single-tank solar water-heating systems, with three main functions: collector differential-temperature circulation, tank constant-temperature control, and pipe heating (or collector freeze protection).
Product
Product key features
Function 1: Differential-temperature heat-collection circulation between the solar collector and heat-collection tank, with protection functions: high-tank-temperature circulation stop, collector freeze-protection circulation, and protection against tube bursting caused by an excessive collector-tank temperature difference
Function 2: Thermostatic control of insulated water tank
Function 3: Independent temperature control for heat tracing cable freeze protection or return water temperature maintenance
Both heat-collection circulation and electric heating use high-current relay outputs. The heat-collection circulation output can directly drive a 500W pump, and the tank constant-temperature heating output can directly drive a 2000W electric heater.
The collector temperature probe uses an NTC230K thermistor with a high-temperature-resistant design, withstanding temperatures up to 250°C
The water tank temperature probe uses a waterproof sensor and can be immersed directly in water for temperature measurement.
Collector temperature, water tank temperature, and other thermostat temperature measurements are all displayed to one decimal place
Three-way temperature measurement deviation correction
Intelligent power supply design automatically adapts to AC80V–240V for stable, durable, uninterrupted operation worldwide
