What it is
The Siemens AGU2.111A109 is a clip-in relay used in Hamworthy gas boilers, handling both 0-10 V and VFC (voltage-free contact) control signals. It forms part of the boiler's control interface, allowing the appliance to accept an external modulation or enable demand. It is supplied under Hamworthy part number 533901438.

Before you order
