Solar priority
137
Parameters
No. of functions included
Enter the number of functions included
Included functions
Sub-menu: List all solar functions
Priority
(list of the included solar
functions)
Specify the priority level
If Off is entered, the relevant solar function is disabled.
Lower prio. timer
from priority level
Specify the priority level from which relative priority is to apply.
Absolute priority will apply below that. If 1 is entered, relative priority
will apply to all levels.
Threshold value
(shown only with radiation
sensor)
Activation threshold in W/m² for the priority timer. This threshold must
be exceeded at the end of the runtime in order for the priority timer to
be able to start with the idle time (60 seconds).
Runtime
ON time of the lower priority consumer, until the next start of the
priority timer
Delay
The collector must be able to reach the start temperature for the
higher priority consumer within this time otherwise the system will
continue to charge the lower priority consumer.
Flushing duration
Specify the duration of the flushing period after the idle time. About
half the content of the collector must be pumped past the collector
sensor during this time.
➢ The program automatically looks for all of the values needed in the included function
modules and also automatically blocks the included modules that are lower in priority. The
action of the priority function is visible in the output variables of the solar functions.
➢ Equal priority levels can be assigned as well. However, this is generally only useful if the
system has multiple collector arrays. In that case, solar functions which apply to the same
cylinder are set to the same priority level.
➢ If, for example, Lower prio. timer from priority level 2 is specified, the solar functions with
priority 1 will be permitted first until the consumers have reached their maximum
temperatures (absolute priority). Only then does the priority processing of the other solar
functions begin, via the priority timer (relative priority).
➢ If the Runtime is set to 0, absolute priority will apply to all the included solar functions.
➢ If the activation threshold of the radiation sensor is set too high and solar functions become
active even though the threshold has not yet been reached, absolute priority will apply to
those functions.
Output variables
Flushing process
Pump status ON/OFF; selection of the output for the flushing process
Runtime counter
Display of the runtime (which starts 15 seconds after the end of the flushing
time)
Delay timer
Display of the delay (which starts when the priority timer starts)
Absolute priority
Status ON when absolute priority is active via the from priority level entry or
the Runtime is set to 0. The starting of the next level will not be permitted as
the priority levels with absolute priority have not yet reached their maximum
temperature.
➢ If the priority timer has been started with the delay and a start situation for a higher priority
consumer arises within that time, that higher priority level will only start after the delay and
flushing time + 15 seconds. During the runtime, the changeover from the lower priority to the
higher priority takes place immediately.
