Solar water heater pump controller.
3 less than 600w inputs.
It is used for the solar hot water heating system.
The controller is there to turn the pump on when the fluid in the solar panel is hotter than the water in the hot water tank or swimming pool and keep it turned off at all other times.
The spp isolar 2 is a solar controller for solar thermal systems.
12v or 24 vdc pumps.
Both refer to the temperature difference between the solar water heater panel outlet and the sensor location at the hot water cylinder intake.
It is what controls the flow of heating fluids and water based on programmable temperature differential measurements.

0 50 dc volts pv array.
Pool owners can even maintain their pool and spa at different temperatures.
This solar controller can be used to monitor and operate the solar thermal systems via the single relay control used to operate the solar pump.
Degree suitable power of pump.
Swhcyltdiff and swhtdiff are the two set points that control the operation of the solar water heater pump during normal operations.
The solar control system is both the heart and brains of a solar water heater.
Control the main solar panel circuit pumps at 2 levels reducing water flow as temperature delta decreases via lead and lag pumps lets the system collect solar more efficiently publish temperatures and pump status to a web page and provide the same pump control as available on lcd user interface.
Degree range of tank temperature measuring.
A solar water heating pump controller is a key component in most solar water heating systems diy or otherwise.
Degree range of collector temperature measuring.
Less than 3w accuracy of temperature measuring.
The isolar 2 is a standard differential controller used to turn a solar thermal on and off via pump controls.
When the temperature reaches the set value it automatically runs the water pump circulation and makes the two temperature zone temperature equilibrium.
Solar pump controller lcb 10a dc pump controller linear current boosters used in solar direct pumping applications compatible models.
1 pt1000 sensor less.
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.
