8.3.x. Priority test
If there is more than 1 tank in the configuration, priority test can be
enabled to periodicaly test the collector temperature if it has enough
high temperature to start filling the prioritiy tank again.
After priority tank is filled (or [T MAX tank1] or [Tcoll. < TDcoll-
tank]), solar heating is switched to the next tank according the priority.
By enabling Prioritiy test function, next tank by priority will be filled for
some time (set under Priority filling) after which it will stop for some time
(set under Priority pause) to check if the collectors can fill priority tank or
they will continue to fill current tank. If the collector temperature increase
in the set pause time is higher or equall [3°C/x min.] pause time is
extended until increase of the collector temp. is higher ie. until is
possible to fill priority tank again. If the increase of the collector temp. in
set time is lower than [3°C/x min.] filling the current tank continues.
By enabling Priority test function in menu 1. Tank, menus Priority filling
and Priority pause are shown.

8.3.9. Priority pause
Priority test -> ON
Pause time for the collector pump in which is tested rise of the collector
temperature to switch back to heat priority tank.
If the temperature rise in the set pause time is higher or equal [3°C/x
min.], time of the pause is extended for next interval, in which rise of the
collector temperature is tested and possibility to start to heat priority
tank. If the temperature rise in set pause time is less than [3°C/x min],
current tank continues to be filled.
