I have a blank screen / no display and new batteries do not bring the screen back on ?
If the batteries are not changed with the correct procedure (ie. all
owing time for the internal capacitors to fully discharge before the new batteries are fitted) or before the batteries become totally drained, the thermostat can go into a locked / suspended state and appear to not work. Your thermostat is not broken, but you need to click on the link below and follow the procedure :
(Refer to: Common Issue and Q&A / Common Issues / No Display Doc. 7.2.1)
My receiver has a flashing red light, what does this mean ?
A flashing red light on the receiver means the Receiver and Thermostat have lost their communications link and the devices need pairing.
(Refer to: Common Issue and Q&A / Common Issues / Red Flashing Light Doc. 7.2.2)
Why does my screen show 5’C and not let me increase the temperature ?
This is because your Thermostat is in Frost Protection Mode. Simply Press the Frost Button to exit Frost Protection Mode and then you will be able to change the temperature.
(Refer to: Common Issue and Q&A / Common Issues / 5’C Frost Mode Doc. 7.2.3)
I have a RT510RF can I make it internet controllable?
No, the RT510RF does not support internet control. You would need a new full kit of iT700, iT800 or smart home range with internet availability at the installation’s location.
Does the RT510TX pair with the RXWBC605 receiver?
The RT510TX does pair with the RXWBC605.
Check you got the RXWBC605 instead of the RXWBC600 that look identical but is the older version and would not pair to a RT510TX.
How do I change the differential value, temperature swing, ITLC and SPAN, on a RT510RF?
You can change the differential value on the RT510RF by using the two DIP switches on the back of the thermostat.
When ITLC is selected on DIP switch № 2, the DIP switch № 1 is functional. You can choose between radiator or electric heater.
When Span is selected on DIP switch № 2, the DIP switch № 1 is not functional.
Can the RT510TX be used with the Salus iTG310?
No, the RT510TX does not support internet control so will not pair with any gateway.
What to do when RT510TX screen is frozen and buttons do not respond?
Remove the batteries for 30 minutes to let the RT510TX reset. If this does not solve the issue create a support ticket.
My RT510TX is constantly losing time?
Take the batteries out for 30 minutes to let the thermostat to reset. If this does not solve it, create a support ticket.
Can you delete a set program in the RT510 or RT510TX thermostats?
No, you cannot delete a program in the RT510 series, only edit or set it to permanent manual mode to ignore schedule.
Can I change my RT510RF for a different thermostat?
No, the receiver you have fitted that works with the RT500RF or RT501RF wont pair with other Salus models. Both thermostat and receiver will need replacing with any upgrade
Is RT510 suitable thermostat to pair with RXRT510?
No, the RT510 is a hardwired model and cannot be paired with a wireless receiver. The RT510TX is the required mode for wireless pairing
RT501RF not turning boiler on any more?
Ensure the Salus boiler receiver switch is set to Auto (the hollow circle)
- Then turn the boiler off at the mains power switch for 10 seconds
- When power comes back on you may notice the LED on the receiver flash then turn to OFF.
- Press and hold the SYNC button on the receiver until the red light starts flashing. (The SYNC is the black round button on the receiver).
- On the thermostat hold the SELECT button until the screen shows 10SY
- Ensure you are at least a metre away from the receiver
- After a few seconds the red flashing light should go out
- Hold the SELECT button down to get back to the main screen
After switching power back on, the receiver light flashes then goes off before I can pair it to the thermostat?
When you power up a receiver, the flashing light indicates the receiver’s firmware version and is not a pairing state. After powering the receiver up, let it flash then stabilise – it goes off for plugin receivers, or shows a solid red light for wall mounted receivers.
On plugin receivers, press and hold the Sync button under the LED light for 3-5 seconds until you get a flashing red light – this is the pairing state.
On wall mounted receivers, slide the On/Off switch to Off and back On as fast as you can to get a flashing red light – this is the pairing state.
Now initiate pairing on the thermostat.
The wall mounted receiver red LED will go solid on a successful pair. The plugin receiver red LED will go off or stay solid on, depending on whether the thermostat is already calling for heat or not.
My RT510RF has lost the wireless connection to the receiver and they won’t re-connect?
The thermostat and receiver will need to be re-paired to regain control of the heating. Please follow the pairing steps carefully, to ensure the thermostat and receiver are put into pairing mode.
- Ensure the receiver switches are set to Auto and On
- Turn OFF the boiler at the mains switch on the wall for 30 seconds
- Turn the boiler back on - the receiver red and green lights should briefly flash then settle on a red solid light
- Quickly flick the receiver on/off switch from its current ON position to OFF and ON, to get the red flashing light
- On the thermostat hold the test / pairing button down to get SYNC10 on screen
- Ensure you are at least a metre away from the receiver
- After a few seconds the red flashing light should turn solid
- Hold the test / pairing button down to get back to the main screen

I have synced the RT510RF thermostat but it’s not heating my home?
The thermostat and receiver must be paired for the heating to work. When the RT510TX is calling for heat, the Green LED on the RXRT510 receiver is on. If the green LED is on but the heating is still not coming on, the issue is likely with the heating system itself – please contact a heating engineer.
I have an SRT code instead of a SAT when registering on the app with the RT510?
The RT510 is not an internet / app-controlled device, so it cannot be paired with a gateway. If you are looking to register an app-controlled device: the RT310i has an SRT number in the battery compartment, and the IT500 has an STA code.
The RT510 device looks like it’s functioning but doesn’t heat up the radiator?
The RT510 is a wired thermostat connected to a motorised valve or pump. When it is calling for heat the internal switch is active. If the heating is still not coming on, this points to a physical issue with the valve, pump or wiring – please contact a heating engineer.
