Factory default set:
The first time - section of heating starts at 04:00and stops at 05:00 a.m.
The second time - section of heating starts at 10:00 and stops at 10:00 a.m.
The third time - section of heating starts at 17:00 and stops at 22:00 p.m.
For all time - section, default temperature for control back-up heating is triggered at
temperature of 40
o
C, and stopped at temperature of 50
o
C.
If it is needed to deactivate the back-up heating function in one time - section, then just
set the start time and stop time with a same value, for example, for the second-time -
section, the start time is 10:00 a.m, and the stop time is also 10:00 a.m.
Within three time - sections, the adjust range of the switch-on temperature is 0
o
C ~
(OFF-2
o
C), and the switch-off temperature is (ON+2
o
C) ~ 95
o
C.
SMT: Intelligent heating
At the case that solar energy is insufficient to heat the tank, to ensure user has sufficient hot
water, controller will check the temperature of tank automatically at the pre-set time - section,
if tank
’s temperature is not reached to the desired temperature, then back-up heat producer
will be triggered, and when tank
’s temperature rises to the desired value, then back-up heat
producer is stopped.
Factory set (unchangeable) of SMT function:
Default at 13:00 of the first time - section to trigger the back-up heat device to heat tank
to 30
o
C,
Default at 14:00 of the second time - section to trigger the back-up heat device to heat
tank to 35
o
C,
Default at 15:00 of the third time - section to trigger the back-up heat device to heat tank
to 40
o
C,
Default at 16:00 of the forth time - section to trigger the back-up heat device to heat tank
to 45
o
C,
Default at 17:00 of the fifth time - section to trigger the back-up heat device to heat tank
to 50
o
C.
