5-HYDRAULIC CONNECTION
HYDRAULIC KIT
The boiler comes with a complete kit for the production of domestic water, comprising:
• A plate heat exchanger
• A three-way diverter valve
• A flow switch
• Pipes and fittings for connection
The kit is designed to heat domestic water directly from the domestic water supply system. The manufacturer supplies the kit ready
assembled.
When the tap is turned on and hot water is needed, the internal water flow switch will send a signal to the diverter valve to channel the
hot water from the boiler to the plate heat exchanger. The temperature of the domestic water depends a great deal on the temperature of
the water inside the heating system. This can be calculated to a good degree of accuracy by taking 10°-15°C away from the value shown
on the control panel of the boiler (which is the temperature of the water in the boiler).
If domestic water is needed while the boiler is in ECOSTOP mode, the boiler will automatically and immediately begin the start-up process
to heat the water inside the boiler, followed by the domestic water after 30 seconds.
