This handbook contains instructions on how to install and configure the Intelligent Energy Controller (IEC).

IEC operation

The IEC sits between an outdoor temperature sensor and a regulating device (i.e. a controller).

Its main functions are:

  • to provide an interface for an outdoor temperature sensor
  • to emulate an actual temperature sensor
  • to interface with 1-Wire temperature sensors
  • to interface with an energy meter
  • to communicate with the NODA cloud platform

As an outdoor temperature sensor interface, it supports a range of temperature sensors that can be connected. See section Input modes for details.

The outdoor temperature reading, i.e. the reference temperature, is sent to NODA's platform along with readings from 1-Wire temperature sensors and the energy meter.

NODA's system calculates the optimal change in temperature for the (heating/cooling) system, based on the outdoor temperature (reference), gathered data, system parameters and various operational targets. This calculated temperature is then transmitted back to the IEC.

As a temperature sensor emulator, the IEC then feeds a customised temperature value to the controller, i.e. the calculated temperature.

This change the controller's measured outdoor temperature, which in turn decreases or increases the heating/cooling of the building.

The data exchange between the IEC and NODA is once every 10 minutes.
