Collector emergency shutdown
When the collector temperature exceeds the adjusted coll-
ector emergency temperature (CEM / CEM1 / CEM2), the
solar pump (R1 / R2) is switched off in order to protect the
system components against overheating (collector emer-
gency shutdown). If the maximum collector temperature is
exceeded, is displayed (flashing).
COL(1,2) / CEM(1,2)
Collector emergency
temperature
Adjustment range: 80 ... 200 °C
in steps of 1 °C
Factory setting: 130 °C
Switch-on hysteresis: -10 K
Note:
If the drainback option ODB is activated, the
adjustment range of the collector emergency
temperature is changed to 80 ... 95 °C. Factory
setting in that case is 95 °C.
COL (1,2) / OCCO(1,2) /
CMAX(1,2)
Collector maximum temp.
Adjustment range
: 70 ... 160 °C
in steps of 1 °C
Factory setting
: 110 °C
Switch-on hysteresis: -5K
Collector cooling
This function is used for keeping the system temperatures
and consequently the thermal load as low as possible.
When the store temperature exceeds the adjusted ma-
ximum store temperature, the system stagnates. 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 store temperature may then exceed the
maximum temperature, but only up to 95°C (emergency
shutdown of the store).
If the collector cooling is active, is displayed (flashing).
COL(1,2) / OCCO(1,2)
Adjustment range
ON / OFF
Factory setting
: OFF
Note:
This function is only available, if the system
cooling function and the heat dump function
are deactivated.
COL (1,2) / OCMI(1,2) /
CMIN(1,2)
Collector minimum temp.
Adjustment range: 10 ... 90 °C
in steps of 1 °C
Factory setting
: 10 °C
Minimum collector limitation
COL(1,2) / OCMI(1,2)
Collector minimum temp.
Adjustment range
: ON / OFF
Factory setting
: OFF
The minimum collector temperature is the minimum switch-
on temperature which must be exceeded for the solar pump
(R1 / R2) to switch on. The minimum temperature prevents
the pump from being switched on too often at low collector
temperatures. If the collector temperature falls below the
adjusted minimum temperature, is displayed (flashing).
In the adjustment channel n1(2, 3)LO, a relative minimum
speed for connected pumps can be allocated to the outputs
R1, R2 and R3.
Minimum speed
PUMP1 (2, 3) / n1 (2, 3 LO
Speed control
Adjustment range: 20 ... 100 %
in steps of 5%
Factory setting: 30 %
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.
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.
