CMn:
collector minimum temperature
adjustment range:
10 ... 90 °C
50 ... 200 [°F]
factory setting:
10 °C; 50 [°F]
Option collector minimum limitation
OCn:
collector minimum limitation
adjustment range: OFF / ON
factory setting: OFF
The collector minimum limitation option prevents the solar
pump from being switched on too often at low collector
temperatures. When this option is activated, the collector
minimum temperature can be adjusted.
The collector minimum temperature is the temperature
which must be exceeded for the solar pump (R1) to switch
on. If the temperature falls below the minimum temperature,
(flashing) is shown.
CFR:
antifreeze temperature
adjustment range:
-10 ... 10 °C
10 ... 50 [°F]
factory setting:
4.0 °C; 40 [°F]
Antifreeze option
OCF:
antifreeze function
adjustment range: OFF / ON
factory setting: OFF
The antifreeze function activates the loading circuit between
the collector and the tank when the temperature falls below
the adjusted antifreeze temperature at the collector sensor.
This will protect the fluid against freezing or coagulating.
When this option is activated, the antifreeze temperature
can be adjusted.
If the adjusted antifreeze temperature is exceeded by 1 °C
(2 °Ra), the loading circuit will be deactivated.
Option recooling
If the adjusted maximum tank temperature (
S MX
) is
reached, the controller keeps the solar pump running in
order to prevent the collector from being overheated.
The tank temperature may increase, but only up to 95 °C
(200 °F) (emergency shutdown of the tank).
If the tank temperature is higher than the maximum tank
temperature (
S MX
) and if the collector temperature is at
least 5 K (10 °Ra) below the tank temperature, the solar
system remains activated until the tank is cooled down
below the adjusted maximum tank temperature (
S MX
)
via the collec tor and the pipework.
OREC:
option recooling
adjustment range: OFF / ON
factory setting: OFF
note:
Since this function uses the limited heat quantity
of the tank, the antifreeze function should be
used in regions with few days of temperatures
around the freezing point.
if the OREC option is additionally activated:
If the tank temperature is higher than the maximum tank
temperature (
S MX
) and if the collector temperature is at
least 5 K (10 °Ra) below the tank temperature, the solar
system remains activated until the tank is cooled down
below the adjusted maximum temperature (
S MX
) via the
collector and the pipework.
If the system cooling function is activated, (flashing) is shown.
Due to the cooling function, the system will have a longer
operation time on hot summer days and guarantees thermal
relief of the collector field and the heat transfer fluid.
