Diagrams and Components

Figure 1: Kit Components

This diagram illustrates the assembled safety kit with circulator and separator. Key components identified include:

• Adapters (DN50, DN40, DN80)
• "Y" Filter
• Modulating Pump
• Mixing Header (DN100)
• Support Brackets and Adjustable Foot
• INAIL Safety Kit Manifold: This includes a minimum water pressure switch, a maximum safety pressure switch, a thermometer (0°C to 120°C), a safety thermostat, a control well for the thermometer, a VIC bulb well, and connections for a pressure gauge (with a 3-way tap and shock absorber tube). It also notes the safety valve (not supplied) with a maximum calibration pressure of 5.4 bar, with one valve for up to 580 kW and two valves for over 580 kW.
• Expansion Vessel (optional, depending on power requirements)
• Automatic Air Vent Valve
• Dirt Separator Connection

Water content of the kit is 1.41 liters.

Figure 2: Mounting Dimensions and Component Positions

This diagram provides essential mounting dimensions and shows the spatial arrangement of the main components of the kit. It includes height and depth measurements for different model capacities (up to 150 kW, 200-250 kW, 300-350 kW) and indicates the placement of the pump, filter, expansion vessel, and mixing header.

Electrical Connections

This section details the electrical connections required for the kit. It shows a schematic linking the main electrical panel (Q.E., not supplied) to the kit components. Key connections include:

• Power supply (230 V - 50 Hz) via a Wieland mobile power supply socket.
• Terminals for a flow switch (FL).
• Terminals for an external sensor (SE).
• Connection for the modulating pump (C).
• Terminal board for services connection.
• Details for analog inputs (AI 1/2) for 0-10 V signals and digital inputs (DI 1/2).
• Safety Extra-Low Voltage (SELV) connections.
• Bus connections (Wilo Net).

The diagrams also show terminal configurations for analog and digital inputs, including specific pin assignments like '+In', '- GND', '+24V'.

Safety Detail Items (INAIL Safety Kit)

This diagram provides a close-up view of the INAIL safety kit components and their specific wiring connections, particularly when connecting to a BCM (Boiler Control Module) or a terminal block if the "B" terminal block is not present. It illustrates the connections for the minimum pressure switch (1.2), maximum pressure switch (1.1), safety thermostat (1.3), and flow switch (FL). It also details how to remove bridges and connect cables to the BCM or terminal block M2.
