user guide for RADIANT R2KA 24 /20 2V boiler english pdf
Your RADIANT R2KA 24 /20 2V is a gas- fired wall hung high efficiency boiler, which generates heat for hot water production and or heating. R2KA 24 /20 2V boiler can be operated together with a domestic hot water cylinder, which stores a larger volume of hot water. This boiler is fitted with internal hot water production and a domestic hot water cylinder to achieve increased hot water convenience.

Hot water production
When you open a hot water tap sink, shower, bath, etc, the boiler operates automatically and supplies hot water at a temperature set by you. The boiler automatically stops producing hot water. when you close the hot water tap.
Tips
To ensure your system operates properly, have it professionally serviced once a year before the start of the heating season.
Yearly or before the start of the heating season
- Regularly check the pressure displayed by the pressure gauge.
- Make sure the valve is properly closed after filling.
- Check the charge of the thermostat batteries.
- Contact a technician for maintenance and cleaning.
Functions of R2K Boiler
Not to be confused as an error, this Boiler signal different active functions like:
- F08 Heating Anti-freeze: In case of extremely low temperature, expecially if the boiler is installed outside, this function provide an Heating procedure. Wait until the operation is done
- F33 Air Release Cycle: The R2K Boiler try in the next 2 minutes to release all air in the system, this occur generally when you
- FH Fast H20: You can activate or deactivate this function by holding simultaneously for 7 seconds the and buttons of the domestic circuit.
More about FAST H2O Function
The Fast H20 function of the Radiant R2K 24 Boiler provide a constant temperature in the DHW Circuit, according to the temperature setted by the user.
This Functionality can:
- Lower the time needed to provide the hot water to the faucet.
- Avoid the delay and increare the comfort of th final user
