5.13 SANITARY FLOW LIMITER (accessory)

If the sanitary flow rate is too high, it is possible assemble in the boiler the flow limiter. It is available in 3
different flow rate: 8l/min, 10l/min and 12l/min, it is possible identify them with the colour:
8 l/min
The flow limiter must be assembled in the connection between right hydraulic block and sanitary heat
exchanger.

5.14 TEMPERATURE PROBE

To check the delivery and return temperature use the two contact sensor. To read the sanitary water
temperature the boiler uses the sensor NTC2.
If the NTC1 sensor does not work properly the antifreeze function will be checked by sensor NTC2 (only
pump circulation).
