RinNova Cond completes the range of BIASI pre-mix condensing boilers, perfect for radiator systems and suitable for radiating systems with mixing units.

RinNova Cond is a compact condensing boiler, which ensures high efficiency, low energy consumption and respect for the environment.
It is available in the versions for heating and DHW production, with a heat output of 24, 28 and 32 kW.

Main features

  • Primary condensing exchanger in stainless steel with steel coating to offer maximum resistance to corrosion
  • Pre-mix burner in stainless steel (NOx class 6)
  • Modulation 1:5 Methane and also LPG
  • DHW exchanger with stainless steel plates
  • 7-litre expansion vessel
  • High-efficiency pump with low energy consumption
  • Integration with BIASI solar systems with a solar kit
  • Digital pressure reading display
  • Provision for remote control and external probe

Compact brass hydraulic unit. Delivery unit with motorised diverter, by-pass and system filling valve built in.
ErP pump with manual pump release on return unit.

Control panel operation

  • Summer/winter/off selector
  • Heating temperature regulator
  • DHW temperature regulator
  • Digital pressure reading
  • Screen display of DHW and heating temperature
  • Fault diagnostics, lockout conditions and fault log display

The display works in the following modes:

  1. INFO
    Information on the operating status and alarm history
  2. FREE PROGRAMMING
    Parameters can be programmed to adapt boiler/system and user SET
  3. INSTALLER PROGRAMMING
    Generator parameters
  4. SUPPORT PROGRAMMING
    Authorised service centre parameters

Remote controls

The RinNova Cond range has two remote class V commands, in the Basic and Top versions, with a weekly programmable thermostat with up to 4 programmable time periods with independent temperatures. All the information on the boiler display can also be viewed remotely.
