I have been asked by a friend if I can have a look at the dual channel hive he has installed. The heating is working fine but when the hot water is scheduled to come on the heating also comes on. He has completely removed the existing thermostat and wiring. He has replaced the programmer with the hive receiver.
The heating system is a pumped system with vented water cylinder. Boiler is a oil fired convection danesmoor.
The wiring on the hive receiver has live neutral and terminals 3 and 4 connected.
Anyone any ideas as to why the CH comes on when the HW is on.
