The Fusion Hybrid Gas Condens
Fusion Hybrid Gas Condens Fusion Hybrid Gas Condens
Fusion Hybrid Gas Condens module is equipped with an electronic control for efficiently
regulating the automatic functioning of the module. It also has the following additional control
features:

Fusion Hybrid Gas Condens module is configured to modulate between minimum and
maximum burner power. Parameters P08 P08 P08 P08 and P10 P10 P10 P10 may be used to adjust the minimum and
maximum heating power.

Parameter P.12 P.12 P.12 P.12 can be used to adjust the maximum heating setpoint temperature (80ºC by default)
to adjust it to the characteristics of each particular installation, optimising the system's energy
efficiency.

By default, the module is programmed for the circulating pump to continue functioning for 3
minutes when there is no further heating demand. Notwithstanding, this time can be modified
using parameter
P39 P39 P39 P39 , between 3 and 16 minutes.
The recirculating pump operating mode can also be changed using parameter P48
P48 P48
P48 . The operating
modes are as follows:
1: Standard: The circulation pump is activated when the heating demand is enabled and
remains active until the end of the post-circulation time.
2: Continuous: The circulation pump, remains activated with the 3-way valve in the heating
position. If the DHW demand is enabled, the 3-way valve switches to the DHW
position, and the circulation pump remains active until the end of the post-
circulation time.

Parameter P21 P21 P21 P21 can be used to activate the low temperature operation, in order to limit the
maximum heating set point temperature.
P21 = 0: P21 = 0: P21 = 0: P21 = 0: The value 0 is selected so that the radiator systems operate by default at high
temperatures.
P2 P2 P2 P21 = 1 = 1 = 1 = 1: 1: 1: 1: This parameter must be set to 1 for underfloor or heating systems operating at low
temperatures. In this position, the maximum heating temperature is 47ºC.
