eddi has the possibility of installing a relay & sensor card, which allows for many different wiring configurations and includes the following functions:
- two independent multi-function relays (16Amp)
- eSense input (isolated 230V detection for off-peak hours etc.)
- two temperature sensors (PT1000)
The two relays can be set independently for different functions, or they can be set to work as a pair. Relay functions include:
- Export threshold
- Import threshold value
- Use during heating
- Legionella control
- Timed actions
- Fault signal for BMS systems
For more information and diagrams, see the eddi manual (page 28).
