4.6.5 INTV Pump interval function
Note: SR868C8 doesn’t have this function
Description:
This function is useful when collector sensor isn’t installed in collector (sensor installed
on the outlet pipe of collector). In order to measure the actual temperature of collector,
within the preset interval, solar pump is triggered like pulse, so that the hot water inside
collector can flow to the pipe, where sensor is mounted, as the result, the actual
temperature of collector is measured. It is unnecessary to activate this function in all
time, you can use it within a preset time section, default set time is 06:00 ~20:00.
During the period that solar pump is in operating, (the period of running time can be set
by parameter “tRUN”), controlled check the temperature signal of sensor, if the
temperature increases less than 1
o
C, then solar pump is ceased automatically. After
the break time (interval can be set by parameter “tSTP”), same process repeats.
During the period that solar pump is in operating, if measured temperature increases
over 1
o
C, then the next interval is omitted, this omitting repeats when it caters condition
and until the switch-on temperature difference is catered or no more temperature can
be measured. After that, pump interval function recovers to pulse rate-controlled mode.
