System Operation Variants
Variant no. 1
Tank loaded from the solar panel – system with two sensors.
•
Circulation pump control.
•
Tank loading
The solar pump (P1) can work at the time set in parameter C.02 PANEL ACTIVE.
Outside those times the solar pump's operation is blocked.
The tank is loaded until temperature T2 reaches the value set in parameter B.01 DHW
TANK SET TEMPERATURE. Hysteresis for the set temperature is 2K.
The loading of the tank depends on the temperature difference between the solar
panel and the tank (T1-T2).
Parameter D.02 PANEL-TANK DELTA FOR
temperature difference between the solar panel and the tank for activating the solar pump.
Parameter D.03 PANEL-TANK DELTA FOR P1 PUMP OFF determines the
temperature difference between the solar panel and the tank for stopping the solar pump.
During tank loading the controller can modulate the speed of the solar pump for
optimum use of solar energy.
DHW circulation
DHW circulation pump (P3) operates according to the clock and times set in
parameter C.04 CIRCULATION ON.
