4.6.6 BYPA High temperature by-pass function (tank temperature automatically
adjusting)
Description:
High-temperature bypass role is independent of the solar system's operation; the extra
thermal energy of tank can be transferred to other application through this function, as
a result the constant tank temperature can be kept. In order to transfer this extra energy,
it needs an extra pump or electromagnetic valve. (Connect to output port R1).
For example:
If we set the temperature of bypass is 70
o
C, then when tank temperature (T3) rises up
to 71
o
C, this by-pass function is triggered, electromagnetic valve or circuit pump (R1)
and TD controlled circuit pump (P1) will be triggered simultaneously. When tank
temperature (T3) drops to 67
o
C, electromagnetic valve or circuit pump (R1) and TD
controlled circuit pump (P1) will be ceased simultaneously.
