number is selected in parameter
Solar consumer number for collector/tank cooling
. If the temperature
in this tank exceeds the preset critical tank temperature, collector cooling is stopped.
on (active / off)
........... Switching on the function of collector cooling.
crit.storT (°C)
............. Setting a critical tank temperature. Collector cooling by heating the tank selected
in parameter
Solar consumer number for collector/tank cooling
may run only
until the tank temperature set by this parameter is reached. When this temperature
is exceeded in this tank, the collector stops cooling by heating this consumer.
max.coll.T (°C)
........... Max. collector temperature. When this value is exceeded, collector cooling by
heating the tank selected in the parameter
Solar consumer number for
collector/tank cooling
is started, supposed this function is on.
Storage tank cooling function
If the temperature in tank selected in parameter
Solar consumer no. for collector/tank cooling
is higher
than that set in parameter
Max. temp
. (e.g. due to collector cooling), this tank will get cooled via the
collector. Cooling shall start if the collector is cooler by at least 6°C than this tank..
On (active/off)
............ Switching on the function of tank cooling.
Critical collector temperature
If the temperature set in parameter
crit. t.
is exceeded on a solar collector, solar pump is blocked. This
function protects other solar component from destruction by too hot solar fluid.
crit. t. (°C)
................... Solar collector critical temperature.
Solar consumer no. for collector/tank cooling (-)
.................................... No. of solar consumer used for safety functions of collector and tank cooling.
Solar pump control through PWM
If this function is on, the solar pump can be controlled by PWM (intended for high-efficiency pumps).
The pump is controlled by PID controller to the desired temperature difference between solar collector
and the active solar consumer. Upon switching ther solar pump on the power is set to maximum for the
period defined in parameter purge time, then the speed drops to minimum and is increased/decreased
following the predefined period by the set control step.
