Riello RS 25/M BLU FS2 Instrucciones De Instalación, Montaje Y Funcionamiento página 22

NOTES
• The model RS 35/M BLU three phase leaves the factory with an electrical supply setting of 400V. If 230V power supply is used, change the
motor connection from star to delta and change the setting of the thermal relay as well.
• The RS 25-35/M BLU burners leave the factory fitted for two stage operation and must therefore be fitted to the TR thermostat/pressure switch.
If on the other hand you require a burner with single stage operation, insert a jumper between clamps T6 - T8 of plug X4.
MODULATING OPERATION
If the output power regulator kit RWF40 or the converter 0...10V / 4...20mA is connected, in 3-point signal, the thermostat/pressure switch TR must
be removed (if the 4-pole socket becomes unhooked, apply the supplied cover).
Using just the regulator RWF 40 also remove the TL thermostat/pressure switch.
ATTENTION:
!
- Do not invert the neutral with the phase in the electrical supply line. An inversion would lead to lockout due to ignition fail-
ure.
- Replace the components only with original spare parts.
