Hold down the middle button to enter the settings menu and select the TARIFF option. You can set up to three tariffs and a standing charge. Use the – and + buttons to change the tariff value and then middle button to save the changes.
Most customers have a single unit rate (A) and a standing change (X).
If you have an Economy7 meter then you will need to add your second tariff rate (B – night rate) so that your monitor displays daily costs accurately.
Your monitor has the option for a 3rd tariff rate (however this is only required for a very small number of customers).
The bulb icon on your display is to indicate that a tariff has been set. When a bulb icon flashes, this indicates that a tariff is active.
If a customer has set 2 tariffs, then there will be 2 bulb icons showing on the display.
The 1st bulb will flash, if this is active and the 2nd bulb will flash, if the 2nd tariff is active.
If a customer has a set a 3rd tariff, then there will be 3 bulb icons shown on the display.
If all 3 tariffs are active, 1 bulb will appear on the screen to indicate the lowest tariff, 2 bulbs for the middle tariff and a 3rd bulb for the highest tariff.
