solar water heater controller for Split pressurized solar heating system
Major Technical Indicators
1. Power supply: 220VAC Power consumption: <5W
2. Temperature measuring precision: ±2
3. Temperature measuring scope: 0-99
4. Power of controllable circulation pump: <500W
5. Power of controllable electric heating: <1500W
Optional: 3000W
6. Action current of electric leakage10ma/0.1S
Key functions:
1. Power on self-test
A beep at start-up indicates the machine stays in a normal condition
2. Indication of water temperature
Real water temperature inside the water tank and solar collector is shown atthe same time
3. Time
Display the time at any time
4. Heating up-limited
It can set the up-limited temperature 30-80 (it means off the heatingautomatically when manual or constant heating to up the temperature)
5. Heating bottom-limited
It can set the bottom-limited temperature 30-80 (it means open the heatingautomatically when the temperature declines to the line at the basis of startingconstant heating)
6. Temperature difference up-limited
It can set temperature of up-limited at 5-60
7. Temperature difference bottom-limited
It can set temperature of bottom-limited at 3-60
8. Timing heating
You could set three times of the function timing heating everyday, the timecould be precise minute, the temperature scope can be set at 30-80. Just set thetime for 24:00 if you want to shut-off one time of timing heating.
9. Constant heating
After starting the function of constant heating, till the temperaturedeclines to the bottom-limited, then open heating automatically, however whenthe temperature rises to the up-limited, then off heating automatically.
10. Heating shortly
Be able to open or off the heating function manually
11. Temperature difference circulation
When up-limited temperature difference, starting collector circulation; orit will off the collector circulation.
12. Manual circulation
It could set the circulation, after starting 1-99 minutes, it would be shutautomatically.
13. Parameter reset
It is possible to reset all the parameter to be factory setting.
