(1) Do not modify these factory settings unless absolutely necessary. For example, for modification of the boiler for: G20 (H gas) or G31 (propane),
high pressure systems, WTW coupling or CLV overpressure
(2) Factory setting depends on installation type
(3) The parameter is only displayed if the SCU-S191 and the solar control system are present
(4) The parameter is only displayed if the SCU-S191 is present
(5) The parameter is only displayed if the solar control system is connected
n
Maximum flow rate of the solar pump (if connected)
In order for the regulator to calculate the quantity of heat produced by
the installation (parameter kWh), input parameter
SO07
. The
parameter
SO07
is equal to the flow in litres per minute in the
solar circuit.
Establish the
SO07
value with the help of the table below,
according to the configuration of the installation and the number or
surface area of collectors.
When the flow is input incorrectly, the display kWh will also be
incorrect.
The quantity of heat (kWh value) can only be used for
checks carried out for personal reasons.
