Digital input assignment for input control mode

You need to assign one or more digital inputs with non-exclusive associations to define the active tariff.

If a digital input is used for multi-tariff, it cannot be used for an exclusive association (such as Demand Sync), but digital inputs can be shared with a non-exclusive association (such as Alarms). To make a digital input available for setting tariffs, any conflicting associations must be manually removed at the source of the original association.

The digital inputs are used as binary counters to identify the appropriate tariff, where off = 0 and on = 1, and most significant bit (MSB) is digital input 2 and least significant bit (LSB) is digital input 1. By this definition, digital input 1 must be associated with the multi-tariff feature in order to set the tariff to Input mode.

Digital input requirements for required number of tariffs

Number of tariffs required Digital inputs required
Configuration 1 Configuration 2
1 1 (digital input 1) 1 (digital input 1)
2 1 (digital input 1) 2 (digital input 1 and 2)
3 2 (digital input 1 and 2) 2 (digital input 1 and 2)
4 2 (digital input 1 and 2) 2 (digital input 1 and 2)

Configuration 1: 2 tariff assignment using 2 digital inputs

NOTE: There is no inactive tariff with this configuration.
Tariff Digital input 2 Digital input 1
T1 0 0
T2 0 1

Configuration 2: 2 tariff assignment using 2 digital inputs

NOTE: Digital input configuration 00 means that there are no active tariffs (all tariffs are disabled).
