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.

• Programmable using your smartphone or computer
• Secure and energy ecient
• Three system and display congurations
