WARNING
A flow restrictor is installed within the boiler, which limits domestic hot water output flow rate. This limit is: 13 litres per minute (for
model KC 24) and 14 litres per minute (for model KC 28).
Domestic hot water temperature supplied depends on the DHW temperature setting and on the quantity requested by the user. The
temperature of the water mains supply temperature is also a determining factor.
Available DHW litres per minute depend on boiler thermal output and water mains supply temperature, according to the following formula:
K
l = DHW litre per min. = --------
ΔT
where
K represents:
- 393 in KC 24 model
- 419 in KC 28 model
Δt = DHW temperature – water mains supply temperature
For instance, with model KC 24, if the water supplied is at 8°C and you want shower water at 38°C, the value of ΔT is:
ΔT = 38°C - 8°C = 30°C
and the number of DHW litres per minute available at 38°C is:
393
I = --------- = 13.1 [litres per minute - water mixed at tap]

2.4.4. freeze protection function
This boiler is fitted with an anti-freeze protection system, which works when the following functions are activated: SUMMER, WINTER and
CENTRAL HEATING ONLY.
The anti-freeze function only protects the boiler, not the whole heating system.
A room thermostat must be used to provide freeze protection for the central heating system. Please be aware that the
thermostat is disabled when the boiler is in Off mode.
Therefore, if you want to protect both the boiler and the system, use button 3 in fig. 1 to select the WINTER mode .
When the heating water temperature sensor detects a water temperature of 5°C, the boiler switches on and stays on at its minimum heat output
until the temperature reaches 30°C or 15 minutes have elapsed.
The pump continues to operate even if the boiler shuts down.
The anti-freeze function also protects the DHW circuit.
When the DHW temperature sensor detects a temperature of 5°C, the boiler switches on and stays on at its minimum thermal power until the
temperature reaches 10°C or 15 minutes have elapsed (the diverter valve is in the DHW position).
The pump continues to operate even if the boiler shuts down.
2.4.5. Pump and valve anti-shutdown function
If the boiler remains inactive and:
- the boiler operating mode is NOT OFF,
- the boiler is still connected to the mains supply,
the pump and the switching valve activate briefly every 24 hours to keep them efficient.
2.4.6. Operation with (optional) remote control (part number: 0CREMOTO04)
The boiler can be linked to an (optional) remote control (supplied by the Manufacturer), which can be used for setting numerous parameters:
- boiler status
- room temperature
- CH system water temperature
- DHW system water temperature
- CH system or external water heater (optional) activation times;
- boiler diagnostics display
- boiler reset
and others.
