8.4.10 MAX2 Maximum switch-off temperature for heat transfer between heat
exchanger and tank
Description:
Example with system 12
In the case that collector T1, heat exchanger temperature T4 and tank T2 all meet the
switch-on condition, when value of T4 is between the minimum switch-on temperature
MIN2 and its maximum switch-off temperature MAX2, P1 and P2 pump are triggered at the
same time; when T4 exceeds the MAX2, then P1 is ceased. When T4 drops below its
MIN2, then P2 is ceased.
In the case that collector T1, heat exchanger temperature T4 and tank T2 all meet the
