Connection To A Solar Plant ( ); Accessories Not Included In The Supply - Baxi LUNA PLATINUM Instruction Manual For Users And Fitters

14.4 CONNECTION TO A SOLAR PLANT (
(for models 1.12 - 1.18 - 1.24 - 1.32)
The boiler can be connected to a solar plant.
KEY TO ELECTRICAL CONNECTIONS (see diagram B in annex "SECTION" F at the end of this manual).
1
Storage boiler probe for solar plant
2
Solar manifold probe
Connect the system as follows:
• Solar plant storage boiler probe (1) to terminals 7-5 of boiler terminal block M2.
• Probe (2) to terminals 6-5 of boiler terminal block M2;
• Storage boiler probe (4) to terminals 9-10 of boiler terminal block M2 as described in section 14.5.2.
• Connect the pump of the solar plant to terminals 6-7 of boiler terminal block M3 (see wiring diagram in annex "SECTION" B at
the end of this manual).
Before configuring the parameters, connect the probes and accessories required for the SOLAR plant.
CONFIGURING PARAMETERS
• Access menu 2 as described in section 14.2.1 (see key).
• B Configuration then
• B programme row 5890 (Relay output QX1)
• B (anti-clockwise)
• B programme row 5931(Sensor input BX2)
in the figure is now configured).
• B programme row 5932(Sensor input BX3)
the figure is now configured).
When the symbol
After the probes have been configured, access the Solar menu to set the manifold overheating protection (parameter 3850 default
120°C) and the switching on (parameter 3810 default +8°C) and off (parameter 3811 default +4°C) differentials of the pump.
• Access menu 2 as described in section 14.2.1.
• B Solar B
edit and B to confirm.
INSTALLATION OF VACUUM PANELS
When using vacuum panels, the following parameters should be configured (the procedure is the same as that described above):
• Access menu 3 as described in section 14.2.1.
• 3830 ( "---" = INACTIVE) set 30 minutes (solar pump start interval).
• 3831 set 30 seconds (minimum time the solar pump must remain on).

14.5 ACCESSORIES NOT INCLUDED IN THE SUPPLY

14.5.1 EXTERNAL SENSOR
The External Probe, supplied as an accessory, can be
connected to the boiler as illustrated in the figure to the side.
The following procedure is used to set a parameter, called
room influence which is used to determine the importance
of the ambient temperature with respect to the external
temperature and vice-versa (the factory setting is 50%-50%).
E.g.: if the ambient influence is set to 60%, the influence of
the External Probe will consequently be 40% (the greater the
set value of ambient influence, the lesser the influence of the
External Probe will be in proportion, and vice-versa).
The following procedure is used to set ambient influence:
• C then A and C (approx. 6 seconds)
Enduser – Commissioning - Engineer - OEM.
• B "Commissioning"
• B "Temps / mode CH1"
• B programme row 750 (Room influence)
B and choose the % value to assign to the parameter that determines how much the ambient affects the system then
•
