1.10 ADVANCED SUPPLEMENTARY GENERATOR CONTROL (REFERENCE TEMPERATURE ON THE SYSTEM INERTIAL STORAGE TANK)
In addition to standard control, as described in the installation and operating manual, it is possible to subordinate supplementary generator start-up
(F-L terminals on the PCB-TERMINAL BLOCK) to system inertial storage temperature, installed between the generator (PdC and supplementary
generator) and the user systems (fancoil system, radiant system, DHW).
The steps required to configure advanced supplementary generator control:
Disconnect connector "In. W. S."
1.
Connect a 10 kΩ temperature sensor at 25°C between terminals 3-4 on the TERMINAL BLOCK, and set it up on the system inertial storage tank.
2.
NOTE: Maximum length of 30m.
3. Set parameter 110=2.
At this point, if the additional generator is enabled (par.207≠0), the probe installed on the system inertial storage tank operates in place of the
one installed on the delivered Unit, but only during heating function, not during DHW.
The frequency of the compressor is now modulated so that the system inertial storage temperature (par.111) fulfils the temperature calculated by the
climatic curve. If this temperature is fulfilled, the compressor frequency is zero.
To start the supplementary generator, THE compressor frequency needs to have a value other than zero. Accordingly, as soon as the temperature in
the system inertial storage tank fulfils the climatic curve, the generator is disabled.
NOTE:
•
With DHW, standard control applies.
•
System inertial storage is a tank relative to the system and must NOT be confused with the storage of domestic hot water.
