Restrict Data; Tariff; Deferred (Pending) Tariff; Tariff Structure - Honeywell AS302P Operating Instructions Manual

__________________________________________________________________________

10.2. Restrict Data

A dedicated Restriction of Data Notification Command is used to restrict the data made available on the display and to
Type 1 & Type 2 Devices. This command will contain a date from which the data is restricted (this date can be in the past).
All data will still be available to read via the DCC.

11. TARIFF

11.1. Deferred (Pending) Tariff

There is a Command from DCC to set a Tariff on the meter.
This will contain the following information:
•
Tariff TOU Price Matrix (at least one has to be populated)
•
Tariff Block Price Matrix,
•
Tariff Switching Table
•
Tariff Thresholds
•
Standing Charge
•
Currency Units (£ or €)
The Tariff previously set in the meter will continue to be used until the newly downloaded tariff is activated.
Each of these items can have their own Activation Date/Time. If an Activation Date/Time is set in the past, this will be
actioned immediately. It is possible for an Activation Date/Time to be set significantly far enough in the future so that any
new tariff element will never be activated.
A Cancellation Command can be sent to prevent any part of the tariff becoming active.
When the meter changes its tariff structure then Billing Data is captured. If in Prepayment Mode, Billing and Prepayment
Data will be captured.

11.2. Tariff Structure

The meter can operate in either TOU Mode or TOU Block Mode.
Switching times on the TOU can be subject to a Randomisation Offset. This is based on:
- Randomised Offset Limit (A value in seconds in the range 0 to 1799)
- Randomised Offset Number (A randomly generated value between 0 and 1)

11.2.1. TOU Mode

Independent Switching for 48 TOU Registers based on Imp KWh.
