The Economy 7 Quartz from Hortsmann is an electro-mechanical water heating control which can be set to take advantage of cheap night-rate electricity, so that there is a tank of hot water available for the morning.

It comes supplied with its own surface-mounting box, which can also be mounted over a singe or double gang flush wall box (it shouldn't be mounted on an unearthed metal surface). 

Means of disconnection from the supply having at least 3mm contact separation in both poles must be incorporated in the fixed wiring.

We recommend a separate fused circuit from the consumer unit (24 Hour supply) protected by a 15 amp HRC fuse or, preferably a 16 amp MCB. In some cases immersion heater failure can damage the Economy 7 Quartz. Installation of a 100 mA RCD will provide additional protection for the unit. If the Economy 7 Quartz is to be connected to a ring main then the spur feeding the controller should be protected in the same way.
