INTRODUCTIONThank 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 efficient
• Three system and display configurations

Installing the iT500RX Receiver
Replacing an Existing Programmable Controller with the iT500RX Receiver
1. Turn off 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 finally mount back onto this.
4. Loosen the screws at the bottom of the receiver unit, unclip the front of the unit and fit the back of the
receiver unit to the wall using the fittings supplied.
iT500 User Reference Manual 11
5. Connect the wires in the electrical box to the terminals of the iT500RX Receiver in the correct sequence.

iT500 User Reference Manual20
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 first 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 flash. 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.

Days are numbered 1 to 7 where 1 is Monday and 7 is Sunday.
Days can be programmed individually or in groups. Groups are as follows; 1-2-3-4-5 (weekdays) plus 6-7
(weekends), or 1-2-3-4-5-6-7 (whole week).
In other words you can set up different programs for the weekend compared to weekdays, or have the
same programs for the whole week, or have the different programs for every day of the week.
For One Central Heating Zone plus Hot Water you have the same program options as above for the central
heating zone. For the hot water you have the following options:
• Number of programs per day:
For each day or group of days (weeks, weekdays and weekends) up to 3 program ON/OFF times can be
set. These must be set sequentially, i.e. the OFF time for program 1 must be later than the ON time for
program 1, the OFF time for program 3 must be later than the ON time for program 3.
Failure to set programs sequentially will result in conflicts which will have to be re-set.
• Days the programs apply to:
Same as for above.
