5.3.3 Input E2
• E2 as binary input:
A presence indicator, switch or key can be directly connected here
If a presence indicator (or switch) is used, the period of comfort mode is determined by the
indicator, i.e. comfort mode remains in force for as long as presence is indicated.
If a presence key is used, operation switches without time limit from standby to comfort
mode when presence is indicated.
If presence is indicated during night operation, comfort mode is activated for a limited time.
Because the presence key is often not reset when the room is vacated, the presence input is
automatically reset when the defined operating mode is changed, so that a night reduction, for
example, can take place.
The selection between key and indicator is made on the "Operating mode" parameter page.
The type of presence contact can be set on the "External interface" parameter page.
• E2 as analogue input for an external sensor
With this configuration, all settings are made on the "Actual value" parameter side.
An external sensor (Order No. 907 0 191) is connected to E2.
The maximum permitted line length is 10m.
Important:
If E2 is declared as actual value input, the "Input for actual value" selection cannot be
changed on the "Actual value" parameter page.
