[KB46]

Installing the dual thermostat to new Tempest indirect system. The thermostat appears to be Italian and the wiring diagram does not make sense.

New layout has Worcester Bosch boiler and controlled with a dual Hive, house + HW. Hive CH granny flat, and Hive UFH.

Cannot make sense of wiring diagram supplied.
