eddi relay & sensor board

eddi has the option to install a relay & sensor board, allowing for many different wiring configurations, to support an inductive load up to 3.68kW.

This includes the following features:

– Two independent multi-function relays (16Amp)
– eSense input (isolated 230V detection for low tariff etc.)
– Two temperature sensor inputs (PT1000)

The two relays can be independently set for several different functions, or they can be set to operate as a pair. The relay functions include:

– Export Threshold
– Import Threshold
– Operate when heating
– De-stratification pump control
– Timed operation
– Fault signal for BMS systems

Please refer to the eddi manual (page 28) for the eddi – Relay & Sensor board fitting diagrams.
