INTRODUCTION

Thank you for choosing the Salus iT500 Series of Internet enabled programmable heating/cooling controls.
We hope that your purchase will give you many years of active and trouble-free service.

This equipment can replace an existing domestic central heating and hot water programmable controller and
thermostat or can control a completely new installation.

It is estimated that using a programmable thermostat can save up to 20% of the energy used by a traditional
installation.

The equipment can be used without the Gateway unit. In this case the battery powered central Thermostat
unit will communicate only with the Thermostat Receiver and cannot be accessed remotely.

Features

• Access and control your heating and hot water system via the internet using a smartphone or computer

• Programmable using your smartphone or computer

• Secure and energy ecient

• Three system and display congurations

INSTALLATION

Introduction

The iT500 Thermostat and the iT500RX Receiver are designed to replace the programmer and wired
thermostat in a traditional domestic heating arrangement.

The equipment can be congured to control the following arrangements:

• Heating only, 1 zone

• Heating only, 2 zones

• Heating plus hot water

The system can be remotely controlled, via the internet, by connecting the system to your wireless router.

Installing the iT500TR Thermostat

The iT500 Thermostat is portable and can be located anywhere, providing it is within range of the iT500RX
Receiver.

If necessary, install the batteries in the iT500 Thermostat (see Battery Replacement).

Fit the wall mounting bracket and clip the Thermostat to the wall, as follows:

1. Attach the wall mounting bracket to a suitable wall using the ttings supplied and the built in level.

Note: For best results mount the iT500 Thermostat 1.5m from ground level.

2. After rst ensuring that the bracket is secure, clip the iT500 Thermostat into place by aligning the recess
on the back of the unit to the bracket and clipping into place.

3. Once clipped into place, ensure the unit is securely seated on the bracket.

Pairing the iT500 System Units for the First Time

Once the iT500 Thermostat and the iT500RX Receiver are physically installed, the two units need to be ‘paired’.
Pairing allows the two devices to recognise each other and to communicate wirelessly.

When powering on the iT500TR Thermostat for the rst time, the Thermostat will go through the sequence
of screens shown below and automatically try and pair by searching for the strongest signal from an iTG500
Gateway.

The units attempt to pair for 10 minutes and during this time, the

Installing the iTG500 Gateway

Connecting to your Router

Using an RJ45 cable, connect the Gateway to your router (connected to the internet), connect the supplied
power cable to the Gateway and plug it into the 230V power supply. When all the connections are completed,
turn on the power supply. This is the rst step in enabling you to control your central heating from outside of
your home using your mobile phone or a remote computer.

The light on the router will ash red when it is rst connected and setting up. When connected to the SALUS
Controls Server it will display a constant green light.

Note: Check that your router is allowing the gateway access to both incoming and outgoing connections.
See your router’s operation manual for details on security and TCP/UDP port settings.

1. The gateway requires a xed IP address.

2. You require port 80 and 2165 UDP open.

3. Estimated use per month is 20mb.

Installing an iT300TX Temperature Sensor Transmitter (optional)

The iT300TX Temperature Sensor Transmitter is purchased separately. It is only used if your system supports
two central heating zones. The unit is portable and should be located in the area of your home heated by the
Zone 2 radiators.

1. Remove the battery cover on the back of the iT300TX.

2. Insert the 2x AAA batteries supplied into the iT300TX.

3. Replace the battery cover.

4. Attach the wall mounting bracket to a suitable wall using the ttings supplied.

5. Align the grooves on the back of the iT300TX and slide onto the bracket.

6. Once in place, ensure the unit is securely seated on the bracket.
