Hints and Tips
1. Receiver RED LED ‘steady on’
This could be an indication of dead batteries, or some temporary interference with the radio signal.
2. Commissioning
If nothing has happened after 20 seconds of holding the INSTALL button pressed, check the TLX 7506 thermostat is still
transmitting (i.e. it may have been more than 5 minutes since it was started)
3. Minimum set point
If while adjusting the Set Point it is found that it cannot be set below 16°C, check with the installer that the unit has not been
configured to restrict the minimum Set Point. (This is often required for installations in sheltered accommodation). See
‘CONFIGURING’ above for details of how to re-configure the unit.
4. Failure to operate
If the heating fails to come on when the thermostat is calling for heat, check the ‘Battery Low’ indicator on the thermostat
display. If the display has faded, replace the batteries as you may have previously overlooked the battery low indications. If
the batteries are removed for more than 5 – 10 minutes, the unit may need to be re-commissioned. (See above).
OPERATION
The TLX 7506 Digital room thermostat is simple to use. The large 12MM Liquid crystal display continuously shows
actual room temperature.
To display the temperature requested,(the SET POINT) press and hold the button marked SET. On releasing this button
the display will revert back to actual temperature.

time, press
+

to increase or decrease the temperature setting. The display will continue to show the SET POINT until
the SET button is released. The display will then show actual temperature.
When the TLX 7506 instructs your heating system to switch on,
A small flame symbol appears at the bottom right of the display. This symbol will be displayed only when the thermostat is
calling for the heating to be on.
