6 The settings in detail
2014-07-30
The input / output test is used to check the correct functioning of the connected
components.
When selecting a setting from the relay test, the relevant relay is energized, thus
putting the connected component into operation. The correct functioning of the relays
and wiring can thus be tested.
Important:
During the relay test, limitation of the boiler temperature by the electronic limit
thermostat (TR) remains activated. Other limitations are deactivated.
Selector sensor values are updated within a maximum of 5 seconds.
The display is made with no measured value correction.
6.12 State of plant
The current operating state of the plant is visualized by means of state displays.
