Time Display; Resetting The Unit - Horstmann electronic 7 Installation Manual

For example:
GMT/BST – Switching time will be changed by one hour. In the GMT/BST mode the
clock display will match the actual switching time.
GMT ONLY – Switching will always take place at GMT times (summer and winter).
The clock display will tell the correct time of day.
If Connection is to be made where a 2-Rate electricity meter is controlled by a Radio
Teleswitch or other equipment which control tariffs remotely or seasonally, it is
essential that before setting the commissioning switch you find out how the off-peak
times are controlled.
The Customer Service Centre of your Electricity Supplier will confirm information
regarding Off-Peak electricity timing and the switching method used for your area.
On installations where the 2-Rate electricity meter is controlled by a mechanical
Tariff Timeswitch the commissioning switch should be set to GMT ONLY.

Time Display

The Electronic 7 is fitted with an automatic clock that is pre-set on manufacture and
should not normally require any adjustments by the user.
The clock will automatically adjust the time to Summertime (BST) or Wintertime
(GMT) as appropriate and this setting is always shown on the clock display.
No adjustment is needed to be made by the installer/user.
