Product Details
D-615 is a solar hot-water project controller widely used in solar + heat-pump hot-water systems. Its powerful functions include heat-collection circulation, low-water filling, timed and temperature-controlled water filling, timed tank auxiliary heating, and constant-temperature return water, meeting diverse customer requirements.
The controller's switching power supply supports AC80V～240V input and ensures stable, reliable, and durable operation, guaranteeing controller stability and reliability.
● Function 1: Solar Thermal Cycle
● Feature 2: Lack of running water
● Function 3: Fixed temperature water three times a day
● Function 4: Heating three times a day at regular intervals
● Function 5: Temperature return water
● 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.
● Temperature measurements for the collector, water tank, and other thermostats are all displayed to one decimal place
● Fault alarms: temperature measurement fault alarm and water level fault alarm
● Three-way temperature measurement deviation correction
● Intelligent power supply design automatically adapts to AC80V–240V, ensuring stable, durable operation worldwide.
