Non-drainback systems:
The solar systems pump runs at full power for 10 minutes, pumping
the fluid in the solar system round. If T
col
> T
collector max
after this
has elapsed, the pump will stop running for 30 minutes. After 30
minutes, the pump will start running again and the controller of the
solar heating system checks whether T
col
is less than T
collector max
.
Drain-back systems:
The solar system's pump stops running immediately (for 30
