P3.11 STORAGE TANK
LOADING MODE
With this setting we set the operation mode and priority in
systems with more than one storage tank.
1 - OPTIMAL mode - optimal use of solar energy for d. h. w.
warming with respect to storage tank priorities
2 - AUTO mode - automatic shift between Summer, Optimal
and Winter mode according to the calendar
3 - SUMMER mode - only priority storage tank is loaded until it
reaches set-point temperature. Other storage tanks are loaded
only when the priority storage tank has reached its set-point
temperature. This operation mode is suitable for summer period
when there is no need for room heating
4 - WINTER mode - parallel alternating loading of all storage
tanks. This mode is advisable in winter time, when we wish to
use all available energy for d. h. w. warming and room heating
