SG-Ready Port and PV port: Operation Logic
5
Dip-Switch n. 3 and 4 ON: enables "SG-Ready Port" and "PV port".
This function operates a thermal power limit output control (only for HEATING Mode).
Using Input I1, the PCB operates the "thermal power output control in heating mode by
time limited set temperature downshift", as required by the SG-Ready rule in order to fulfill
the requirements of BEG (Bundesförderung für effiziente Gebäude = federal subsidy for
efficient buildings).
Using Input I2, the PCB operates the "increased thermal power output control".
You can activate the "thermal power output control in heating mode by set temperature
upshift" in order to use, for example, surplus PV energy.
Both channel "Indoor Unit A" and "Indoor Unit B" manage this functions for two AC systems at
the same time.
- Digital Input I1 short-circuit pulse signal: Temperature downshift ( -1,5 °C). Downshift time
interval is set to 120 minutes.
- Digital Input I2 short-circuit static signal: Temperature upshift ( +1,5 °C). Upshift will last as
far as the digital input I2 is in short cicuit.
The first signal that is activated takes precedence over the second.
