Functions and Options

The primary circuit is started up if the precondition for
switching on between collector- und store sensor (Tstu)
is fulfilled (the volume flow is adjusted to the set volume
flow). The secondary circuit is started when the switch
on differential between feed flow and store sensor is ex-
ceeded. If the store feed flow temperature (T-St-FL) in
the secondary circuit exceeds the set store temperature

(Stu-set) including the switch over differential (∆TStu-on),
the switch over valve (V-St) will be switched to the up-
per store range. A shift-in of the lower store range will
take place if the temperature at the store feed flow sensor
underruns the set store temperature plus the switch off
differential (∆TStu-off).
The technician can indicate a volume flow (Vol.) at the con-
troller.
The controller will adjust the volume flow by means of the
RESOL pump activation and the volume flow sensor.
As a cause of the stored system characteristics and the
predetermined heat transfer medium of the primary circuit,
the secondary pump will be adjusted in a way that enables
an optimum heat transfer.
If the switch on condition for the collector circuit is esta-
blished (tube collector function, CS-Bypass or ∆T) the by-
pass pump will be started.The solar pump will be switched
on if the switch on condition between bypass and store
sensor (T-By – lower Tst >= 2,5 K) is fulfilled. The sensor
channel for the bypass sensor (T-Byp) is adjustable.
The primary circuit pump (P1) will be put into operation,
if the preadjusted solarisation threshold (CS-Bypass) at the
solarisation sensor is exceeded. If the solarisation thres-
hold is underrun, the primary circuit will be kept in operati-
on for a specified time span (CS-Delay).The function is only
activated if a solar charge is possible - which means that
neither the sensor nor the collector is blocked.
The aim of the function is to make the collector tempera-
ture accessible for a temperature sensor that is not located
at the collector.
At high collector temperatures (dependant on the e.g. sys-
tem pressure or antifreeze concentration) the water trans-
fer medium is vaporised. This means that a solar loading
isn't possible anymore.
If the adjusted category temperature Tcolemerg. is excee-
ded, the loading of the respective collector is suppressed.
The collector cooling function is started at a set maxi-
mum collector temperature. If this is underrun by 5 K, the
function is switched off again.The collector is cooled by
the heat dissipation to the lower area of the store.(P1 and
P2 are activated).
