CMX:
collector maximum temperature
adjustment range:

factory setting:
120 °C; 250 [°F]
hysteresis: 5 K (10 °Ra)
System cooling
When the adjusted maximum tank temperature is reached,
the system stagnates. As soon as the collector tempera-
ture reaches the adjusted maximum collector temperature
(
CMX
) the solar pump is activated until the collector
temperature is 5 K (10 °Ra) lower than the maximum tem-
perature. The tank temperature may increase, but only up to
95 °C (200 °F) (emergency shutdown of the tank).

factory setting: OFF
Maximum tank temperature
Once the adjusted maximum temperature is exceeded, the
solar pump is switched off and further loading of the tank
is prevented to reduce scald risk or system damage. The
symbol is shown on the display.

maximum tank temperature
adjustment range:
4 ... 95 °C
40 ... 200 [°F]
factory setting:
60 °C; 140 [°F]
hysteresis: 2 K (4 °Ra)
Collector temperature limitation for emergency
shutdown of the collector
If the adjusted collector emergency shutdown temperature
(
EM
) is exceeded, the controller switches off the solar
pump in order to protect the system against overheating.
The factory setting is 140 °C (280 °F) but it can be changed
within the adjustment range of 110 ... 200 °C (230 ... 400 °F).
(flashing) is shown if
EM
is exceeded.

factory setting:
140 °C; 280 [°F]
hysteresis: 10 K (20 °Ra)
note:
The controller is also equipped with a nonadjust-
able emergency switch-off if the tank reaches
95 °C (200 °F).

ference
adjustment range:
1.0 ... 20.0 K
2.0 ... 40.0 [°Ra]
factory setting:
6.0 K; 8.0 [°Ra]
If the switch-on difference (
DT O
) is reached, the pump
is activated. If the temperature difference falls below the
adjusted switch-off temperature difference (DT F) the
controller switches off.
note:
The switch-on temperature difference must be
at least 0.5 K (1 °Ra) higher than the switch-off
temperature difference.
DT F:
switch-off temperature dif-
ference
adjustment range:
0.5 ... 19.5 K
