Battery Replacement - Secure SRT323 User And Installation Instructions Manual

Battery Replacement

The SRT323 runs on 2 x type AAA (alkaline) non
rechargeable batteries and is designed to give a battery
life of approximately two years – under normal usage
conditions.
When the batteries are
nearing the end of their life
a low battery symbol will
appear in the display and
the batteries should be
changed within a few days.
If the batteries are not changed at this point eventually a
'LO' battery message flashes intermittently in the
display and if this happens the batteries should be
changed immediately.
To change the batteries it is necessary to remove the
thermostat from the wall. To do this, first undo the two
captive screws at the base of the thermostat and swing
the thermostat up and away from the wall plate.
