A
7.11 Collector bypass function with 3 way valve (VBY)
User circuit ON:
The 3 way valve releases the user circuit if, with the solar
pump activated, the bypass temperature (TBY) exceeds
the measured storage tank and/or calorifier temperature
plus the
Tank/Calorifier Diff. Off
by 2K.
Collector circuit ON:
The valve switches back to the collector circuit, if the
bypass temperature (TBY) is lower than the measured
storage tank/calorifier temperature plus the
Tank/Calorifier Diff. Off
or the solar pump is
disabled.
A
7.12 Priority solar loading
Loading to yield
This load strategy is used if only limited solar yield is
available, that means when the average pump speed is
below the setting “Switch over operation maximum”. The
advantage is the optimised energy usage with low
collector yield.
Function:
Firstly the tank/calorifier with the lowest temperature level
is loaded, until there is no temperature difference between
the users. Then the DHW tank temperature is increased by
the setting “Diff switch overoperation”. If one user is loaded
to its setpoint temperature, the other is loaded to its
setpoint. Then the swiming pool is loaded to its setpoint.
Now all users are loaded to the respective
... Temp.
Maximum
set.
Once the average pump speed has reached the value of
“Switch over operation maximum”, the load statratigy is
changed from “Loading to yield” to Loading to
temperature”.
The sequence of loading depends on the setting
“Priority solar loading”.
Loading to temperature
This load strategy is used if a larger solar yield is available,
that means when the average pump speed is higher than
the setting “Switch over operation maximum”. Here, the
users are loaded to their respective setpoint temperature
in the sequence set in ‘Priority solar loading”.
Function:
Firstly the user with the highest priority is loaded to its
setpoint value, only then are all other users loaded to their
setpoint value in the sequence set.
Once all users have reached the setpoint value set and if
sufficient collector rating remains the users are loaded in
sequence to the respective
... Temp. Maximum
set.

A bypass valve (VBY) switches between the collector
circuit and the user circuit to stop the solar pump
pulsating if long pipelines or large diameter pipe lead to
the collector and the solar pump can no longer be
modulated by the controller (consumption >1 A).
The activation of the bypass valve depends on the
temperature at the bypass sensor and the storage tank
and/or calorifier temperature.
If one user is not avilable the next user automatically
receives this value.
