Smartphone Thermostat


Please follow the new procedure below:

The RT310i is factory pre-paired as standard. When you power up the receiver, the RED LED will flash.

To test that the receiver and thermostat are paired, navigate to the Pairing Menu by choosing Menu > Pairing > TEST. This will display ‘TESTING 10’ on the thermostat. If the receiver and thermostat are paired correctly, the RED and GREEN LED’s on the receiver will flash. To exit test mode, press and hold the Menu button for 3 seconds.

If the RED and GREEN LED’s on the receiver are NOT flashing, you will need to Re-Pair the Thermostat and Receiver. To do this, slide the ON/OFF switch on the receiver to OFF and then slide it back to ON. The RED LED will now flash. Now, enter the pairing process by choosing Menu > Pairing > PAIR. You will now see ‘PAIRING 10’ on the screen. When the RED LED’s stops flashing, the Thermostat and Receiver are paired.

You can test this again by following the above process.

The RT310i is an affordable Smartphone controlled thermostat. It allows you to control your heating from anywhere via your Smartphone, Tablet or PC. Alternatively, it can be used locally as a simple to use up / down thermostat.

    Brilliant product and part L compliant so I’ve just found out same base plate as the 310 non internet model

    This thermostat works pretty fine especially after firmware update and anabled hysteresis settings.
    It is little slow on response after openning the app on phone (needs about 5-10 sec to recive status and comand from or to thermostat) but afer you once figer it out, it is OK.
    The main thing that is missing is some statistics chart (in the app or on the web) to see how heating/cooling is used.

    I’ve fitted SALUS manual controls in jobs I’ve been on, but when my own wanted updating I chose this one. It’s very simple to set up and use the app to program the boiler. Very impressed with the RT310i and would recommend it. All I can say to others is: Read the manual!
