There are a maximum of 16 Day Profiles.
Each Day Profile can be used in any Week Profile (There is no limit in the number of times a Day Profile can be used.)
A minimum of one Day Profile is required for tariff operation.

11.2.6. Special Days
Up to 50 ‘Special Days’ can be specified, the specification can include ‘Wild Cards’. These days can switch to any defined
Day Profile.
11.2.7. TOU Price Matrix
The Price Matrix sets the cost (in Pounds to 5 decimal places) of energy for each TOU.
This information can be shown to the Customer locally on the meter display or sent to
Type 1 or Type 2 Devices. Price Information is also used for the Prepayment Application
and to calculate Cost Information.
The AS302P contains the ‘Active’ and a ‘Deferred’ Price Matrix which must be configured
for each TOU Rate.
The Price Matrix is for Import Active Energy only.
The Price Matrix applies to all 48 TOU Registers i.e. they all need to be sent at the same
time (it is not possible to update a single TOU Price).
The Price Matrix for future cost of energy can be programmed to activate at a specified
Time and Date.
When the Price Matrix is changed then an entry in the Billing Data Log set is created.
The current Active Tariff Price is determined by the current TOU and the associated Price
from the Price Matrix.
11.2.8. Standing Charge
A Standing Charge with associated Activation Date/Time can be configured in the meter.
The Standing Charge is deducted every day at Midnight.
