Maximum speed
PUMP1 (2, 3) / n1 (2, 3) HI
Speed control
Adjustment range: 30 … 100 %;
20 … 100 % if ADAP and PSOL are adjusted
in steps of 5%
Factory setting: 100 %
In the adjustment channel n1(2, 3)HI, a relative maximum speed for connected
pumps can be allocated to the outputs R1, R2 and R3.
Note
When loads which are not speed-controlled (e. g. valves) are used, the
value of the corresponding relay (n1, n2, n3) must be set to 100 % or the
pump control type must be set to OnOF in order to deactivate pump
speed control.
Collector emergency shutdown
COL(1,2) / CEM(1,2)
Collector temperature limitation
Adjustment range: 80 … 200 °C [170 … 390 °F]
in steps of 1 °C [2 °F]
Factory setting: 130 °C [270 °F]
Switch-on hysteresis: -10.0 K [20.0 °Ra]
When the collector temperature exceeds the adjusted collector emergency tem-
perature (CEM / CEM1 / CEM2), the solar pump (R1 / R2) is switched off in or-
der to protect the system components against overheating (collector emergency
shutdown). If the maximum collector temperature is exceeded,
⚠
is displayed
(fl ashing).
Collector cooling
COL(1,2) / OCCO(1,2)
Selection: OFF / ON
Factory setting : OFF
This function is used for keeping the system temperatures and consequently the
thermal load as low as possible.
When the tank temperature exceeds the adjusted maximum tank temperature, the
solar system is switched off. If the collector temperature increases to the adjusted
maximum collector temperature, the solar pump is activated until the collector
temperature falls below the maximum collector temperature. The tank tempera-
ture may then exceed the maximum temperature, but only up to 95°C (emergency
shutdown of the tank).
If the collector cooling is active,
☀
is displayed (fl ashing).
COL (1,2) / OCCO(1,2) / CMAX(1,2)
Collector maximum temp.
Adjustment range : 70 … 160 °C [150 … 320 °F]
in steps of 1 °C [2 °F]
Factory setting: 110 °C [230 °F]
Switch-on hysteresis: -5 K [-10 °Ra]
Note
This function is only available, if the system cooling function and the heat
dissipation function are deactivated.
