Part 4 – Description of Operation

The clip-in parameter settings can be adjusted on the boiler display or the system interface. Parameter 42.0.0
must be set for the appropriate operation when the clip-in is supplied with power for the first time.
NOTE: When the Clip-In Board is wired and installed it is only possible for a CH demand to be made through the Clip-In. The CH demand through the Clip-In takes priority over all other kinds of requests.

Voltage Power (Parameter 42.0.0 = 1)

The input voltage level determines the proportional power load of the system according to the 0-10 VDC input.
The shape of the proportional relation depends on the following parameters:

The following graph represents the relation to the example values:

• Inlet voltage > 1 VDC – there is a central heating demand – the burner powers on
• 1 VDC < Inlet voltage < 2 VDC – boiler works at minimum power
• 2 VDC < Inlet voltage < 9 VDC – boiler works at power proportional to the inlet VDC
• Inlet voltage > 9 VDC – boiler works at maximum power (100% parameter 2.3.1)
• Inlet voltage < 0.5 VDC – the central heating demand has been met and the burner powers off

2.2 Voltage Temperature (Parameter 42.0.0 = 2)
The input voltage level determines the central heating setpoint of the system according to the 0-10 VDC input.
The shape of the proportional relation depends on the following parameters:

The following graph represents the relationship with the example values:

• Inlet voltage > 1 VDC – there is a central heating demand – the burner powers on
• 1 VDC < Inlet voltage < 3.5 VDC – boiler works at CH setpoint 80°F (par. 42.0.1)
• 3.5 VDC < Inlet voltage < 8 VDC – boiler works at CH setpoint proportional to the inlet VDC
• Inlet voltage > 8 VDC – boiler works at CH setpoint 180°F (par. 42.0.2)
• Inlet voltage < 0.5 VDC – the central heating demand has been met and the burner powers off

2.3 Current Power (Parameter 42.0.0 = 3)
The input voltage level determines the central heating setpoint of the system according to a proportional relation. The shape of the proportional relation depends on the following parameters:

The following graph represents the relation to the example values:

• Inlet current > 5 mA – there is a central heating demand – the burner powers on
• 5 mA < Inlet current < 6 mA – boiler works at minimum power
• 6 mA < Inlet current < 18 mA – boiler works at power proportional to the inlet current
• Inlet current > 18 mA – boiler works at maximum power (100% – par. 2.3.1)
• Inlet current < 4.5 mA – the central heating demand has been met and the burner powers off

2.4 Current Temperature (Parameter 42.0.0 = 4)
The input current level determines the central heating setpoint of the system according to a proportional relation. The shape of the proportional relation depends on the following parameters:

The following graph represents the relation to the example values:

• Inlet current > 5 mA – there is a central heating demand – the burner powers on
• 5 mA < Inlet current < 7 mA – boiler works at CH setpoint 80°F (par. 42.0.1)
• 7 mA < Inlet current < 16 mA – boiler works at CH setpoint proportional to the inlet current
• Inlet current > 16 mA – boiler works at CH setpoint 180°F (par. 42.0.2)
• Inlet current < 4.5 mA – the central heating demand has been met and the burner powers off
