-to set temperature of preset heating .--- to set hour of the second preset
heating time --- to set minute of the second preset heating time---to set
temperature of the second preset heating ---indicating clock condition. For
example: to
Set the temperature of the first preset heating, and for the
indication interface,see Fig.12.
Intellectual heating mode:
Indicating clock condition--the temperature of heating --- indicating clock
condition.
Note: Only when the present working mode is selected, can the
corresponding set content be carried out.
Notes for usage
1.To avoid that water spurts out to the solar stage and the top cover of water-
storing tank directly.
2.To check the functioning of the system regularly and to check whether the
computer board works normally.
3. In order to ensure excellent running of solar water heater, you are suggested
to keep the controller electrified constantly and keep it working under the
solar energy heating mode.
4.In normal use, the tap water entrance valve of water-storing tank should be
kept constantly open. You only need to open the mixed valve to adjust water
temperature when taking a bath and then you can use freely.
5.In summer when water heater is not used for long, the system should not be
closed so as to avoid that the collector is too hot. When empty the system, you
should empty the tank and the collector. The emptying method of the tank is to
close the valve where tap water pipe leads to the hot water system, to open
the decompression handle of tempteture and pressure valve and remove the
single direction valve1 and to empty the tank.
the emptying method of the pipe of circulating pipe:screw down the the cap of
the affusing liquid valve, open the two small halt valves, the antifreeze will
flow from the small halt valve,put it on something,when the antifreeze stop
flowing,close the big halt valve in the middle of affusing liquid valve,connect
inflator to liquid hole,the method is same with the method of affusing
antifreeze, sure the gas direction and the single direction valve2 is same untill
the antifreeze is cleaned up.
6.Please try to connect the probe of sensor to the bottom of the installed hole in
installment or repair. Please avoid that the sensor receives wrong signals.
7.Affusing liquid valve is the key part of the system,aviod to adjust or remove
the 3 handles and 2 screw caps, if temperature of the tank is low, please
