What it is
The Honeywell 42005748 001 is a Sundial Plan wiring centre used to terminate and connect the control wiring between the programmer, thermostats, pump and boiler in a Sundial Plan heating system. It provides a single, enclosed point for the system's control connections instead of loose terminal blocks. The unit is manufactured by Honeywell.
