Off:
There is no speed control. The connected pump is only switched on or off with full
speed.
Mode M1:
Control to the set
Δ
T, starting from max. speed:
After the purging time the controller switches to the set max. speed. If the temperature
difference
Δ
T between the reference sensors (collector and storage tank) is less than
the set value, then the speed is decreased by one stage after the sweep time elapses.
If the temperature difference between the reference sensors is greater than the set
value, then the speed is increased by one stage after the sweep time elapses. If the
controller has adjusted the speed of the pump down to the smallest stage and the
Δ
T
between the reference sensors is
Δ
T off, the pump is switched off.
Mode M2:
Control to the set
Δ
T, starting from min. speed:
After the purging time the controller switches to the set min. speed. If the temperature
difference
Δ
T between the reference sensors (collector and storage tank) is greater
than the set value, then the speed is increased by one stage after the sweep time
elapses. If the temperature difference
Δ
T between the reference sensors is below the
set value, then the speed is decreased by one stage after the sweep time elapses. If
the controller has adjusted the speed of the pump down to the smallest stage and the
Δ
T between the reference sensors is T
Δ
off, the pump is switched off.
Mode M3:
Control to constant collector temperature, starting from min. speed:
After the purging time the controller switches to the set min. speed.
If the temperature at the collector sensor (or the respective R2 relay in variants with
a heat exchanger) is greater than the setpoint, then the speed is increased after the
sweep time expires.
If the temperature at the reference sensor (collector) is less than the setpoint, then the
speed is decreased after the sweep time expires.
Mode M4:
When the primary storage is loaded, speed control works as in M3.
When the secondary storage is loaded, speed control works as in M2.
Setting range: M1, M2, M3, M4, off/Default setting: off

During this time period, the pump is running with full speed (100%) to ensure trouble-
-free startup. After this time has passed, the pump is set to speed control and is set to
max. speed or min speed, depending on the speed control mode (M1-M4) chosen.
Setting range: Purging time 5-600 sec. /Default setting: 8 sec.

Sweep time determines the inertia of the speed control to prevent quick fluctuations in
speed and subsequently also big fluctuations in temperature.
Setting range: Sweep time 1-15 min. /Default setting: 4 min.
