#
Code
Description
N/A
[8‑0C]
Target flow rate during hybrid operation.
The default value is chosen the same as the
target flow rate during boiler operation.
Decrease this value if the room temperature is
constantly higher than the desired room
temperature. Increase this value if you feel
discomfort in hybrid operation.
Range: 10~20 l/min
▪
For EHYHBH05: 13 l/min (default)
▪
For EHYHBH/X08: 15 l/min (default)
The default values have been set to optimise
comfort and performance. Take care when
changing them.
N/A
[8‑0D]
Target flow rate during gas boiler operation.
The default value is chosen to deliver the
nominal capacity of the gas boiler with a ΔT
over the emitter of 20°C. Decrease this value if
the room temperature is constantly higher than
the desired room temperature. Increase this
value if you feel discomfort in gas boiler only
operation.
10~20 l/min (default: 16 l/min)
The default value has been set to optimise
comfort and performance. Take care when
changing them.
Leaving water temperature: Modulation
Modulation lowers or raises the desired leaving water temperature in function of
the desired room temperature and the difference between this temperature and
the actual room temperature. This results in:
▪
stable room temperatures exactly matching the desired temperature (high
comfort level),
▪
less On/OFF cycles (low noise level, high comfort and efficiency levels)
▪
as low as possible leaving water temperatures (high efficiency).
This function is only applicable in case of room thermostat control and is used to
calculate the leaving water temperature. After activation, the leaving water
temperature can only be read on the user interface, but not changed. Turn OFF
modulation to change it. The leaving water temperature can either be a fixed
setpoint, or an offset in case of weather-dependent setpoint.
