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 icon will ash. Pairing should take
approximately 20 seconds.
If the pairing is successful, the icon is turned on all the time.
If the pairing fails or times out, the icon will disappear and the system will retry later.

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.
