# Overview

This document describes how to integrate the source of the heat ON/OFF controlled (boilers, thermal actuators) to CUE system. Any relay in Cue System can be used for control. The relay is driven by the driver Relay Simple Thermostat.

Using the driver is simple and efficient. The driver can be simply inserted to Cue Visual Composer software and objects can be drag and drop to your project. Every instance of the object is customized using object properties.

# Requirements

- Software Cue Visual Composer 5.00 or higher

- One relay or General IO/DigitalIO for switching the heating source

- Temperature sensor connected to the CUE control system, for example sensorCUE, sensorCUE-W, inputCUE-W with Pt1000 sensor or any other 3<sup>rd</sup> party sensor (e.g. Papouch)
