Controllers SGC36HV enable simple and advanced metering of acquired solar energy.
For heat metering it is necessary to have an additional sensor installed into solar collec-
tor’s return pipe
-
cold sensor Tc.
Heat metering is activated with the setting of the parameter W1.1=1. Medium and its
concentration are set with parameters W1.2 and W1.3.
Simple heat metering
By this metering principle it is necessary to read out the max. amount of flow on mechanic
flow meter and enter this value into the setting W1.8 for the first collector field and into the
setting W1.9 for the second collector field, if it exists. By applications with two collector
fields (scheme 236 and 248) it is necessary to enter also the sum amount of flow, when
both circulation pumps are running. This setting is done with parameter W1.10.
Amount of flow needs to be read, when pump is running at its full power or at 100 %
RPM. To do that, manually activate the pump (see chapter Manual mode, page 20).
Connect collector return pipe sensor Tc and perform the setting for sensor selection
W1.5.
HEAT METEUING
Advanced heat metering with volume flow sensor
For advanced heat metering it is necessary to install impulse type volume flow sensor into
the solar circuit.
(pulse encoder). Advanced heat metering is activated with setting the parameter W1.6=1.
Flow quotient of the installed flow meter is set with parameter W1.7.
Connect collector return pipe sensor Tc and perform the setting for sensor selection
W1.5.
Heat metering is in bote cases only informational type and can be used only
as a personal reference. Measured data cannot be used for energy billing or
similar purposes.
Tee procedure for function parameters setting is tee same as tee procedure
for service settings (see page 28).
