TH-0108 Thermostat – “Lo” or blank LCD screen


If “Lo” is appearing on the screen or the screen is blank, then you will need to change the batteries.

 To replace the batteries, you will need to remove the front face of the thermostat from the base of the unit. To do this you will need to press this button.


The cover plate has a hinge on the right side so suggest depressing the button on the left side of the unit as per photo. Use your fingers on the right side of the unit & press your thumb on the “button”. The button is quite stiff so you will need to depress firmly & then give it a tug at the same time as depressing the button.

The unit will then come away & the clips on the right-hand side which act as the hinge will separate & the front section of the thermostat will be free of the base which is still on the wall.

You will now have easy access to the batteries. They are AA size batteries.

  1. If the screen is showing “Lo” on the screen & you are able to change the batteries within about 10 seconds, it will hold its memory of the settings (time, programming) that you have set. 
  2. If the screen is dead & the batteries are not corroded & on changing the batteries the screen jumps into life, you will need to reset settings such as 5:2D or 7D and to set the time & day.
  3. If the screen is dead & the batteries have corroded, then there is a high likelihood that the thermostat will need to be replaced. For details of replacement thermostats please go to the Coldbuster website => https://www.coldbuster.com.au/product-category/thermostats/. 

An electrician will need to install the new thermostat however we strongly recommend not opening the box of the new thermostat until your electrician has carried out a continuity test & insulation test @ 500V to ensure that the heating is in working order. Once you have confirmed that the underfloor heating is working correctly then the electrician can install the new thermostat. If the thermostat is unopened & has not been used it can be sent back to us for a full refund.
