Heat Metering - OEG KSW series Bedienungsanleitung

HEAT METERING

Controllers KSW-E, KSW and KS2W enable simple and advanced metering of acquired
solar energy.
For heat metering is necessary to have a temperature sensor installed into solar collec-
tor's return pipe - cold sensor Tc.
Heat metering is activated with parameter F1.1=1. Medium and its mixture is setted with
parameter F1.2 and F1.3.
Simple heat metering
By this metering principle is necessary to read out the max. amount of flow on mechanic
flow meter and set it with parameter F1.8 for first collector field and with parameter F1.9
for second collector field (only by applications with 2 collector fields).
By applications with two collector fields (scheme 236 and 248) is necessary to set also a
sum amount of flow, when both circulation pumps are running. This setting is done with
parameter F1.10.
Amount of flow needs to be read out when pump is running at its full power or at 100 %
rpm. To do that, manually activate circulation pump (see chapter Manual mode, page 20).
Connect collector return pipe sensor Tc into terminals T5.
Simple heat metering can be used by all schemes with exception of schemes
246 and 246b.
Advanced heat metering with volume flow sensor
For advanced heat metering is necessary to install volume flow sensor (impulse type).
Advanced heat metering is activated with parameter F1.6=1. Impulse rate of installed flow
meter is set with parameter F1.7. Connect collector return pipe sensor Tc into terminals
T4 and adjust the cold sensor setting with parameter F1.5=4.
Advanced heat metering is possible only by following hydraulic schemes:
211 to 220c, 222, 223, 232, 233, 234, 235, 236, 239 and 244 to 246b.
Heat metering is in both cases only informational type and can be used only
as a personal reference. Measured data cannot be used for energy billing or
similar purposes.
