7.5.2 Solar system pump 1 speed modulation
Menu: Service > Settings > Solar system pump 1 speed modulation
The speed modulation function improves the efficiency of the solar thermal system by keeping the
temperature difference within the set cut-in temperature differential.
If the “Double match flow” function is active, the speed is controlled by that function. We recom-
mend leaving this setting activated.
7.5.3 Solar system pump 1 minimum output
Menu: Service > Settings > Solar system pump 1 minimum output
This setting determines the minimum speed of the solar system pump.
In systems with external heat exchanger and 2 heat consumers or systems with external heat
exchanger and East/West aspect function, the pump is run at 100 %.
The minimum pump output for solar system pumps 1 and 2 is always the same with configurations
T3, T7 and H3 (if the output for one pump is changed, the controller sets the others to the same
output).
Warning: risk of damage to system due to pump failure.
V If a pump with internal electronic control circuitry is connected, deactivate the
speed modulation function on the controller.
