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

Installing the iT500RX Receiver
Replacing an Existing Programmable Controller with the iT500RX Receiver
1. Turn o the electrical power to your appliance.
Caution: Ensure that the electrical supply to the appliance has been isolated. Failure to completely
isolate the appliance could cause personal injury by electric shock and possible damage
to equipment.
Remove the cover from the existing programmable controller.
2. Note down the wiring sequence and the cable colours connected to the terminals within the electrical
box.
3. Disconnect the wires from the existing programmable controller terminals and remove.
Note: Providing the existing programmable controller was mounted using a standard electrical box, the
iT500RX Receiver will nally mount back onto this.
4. Loosen the screws at the bottom of the receiver unit, unclip the front of the unit and t the back of the
receiver unit to the wall using the ttings supplied.

5. Connect the wires in the electrical box to the terminals of the iT500RX Receiver in the correct sequence.
See the wiring diagram later on in this section.
6. Once the wiring has been completed, position the iT500RX Receiver over the electrical box xing holes.
Carefully position any wiring back into the electrical box and secure the iT500RX Receiver using the
existing screws.

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 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.
