The ThermoPlus AS2-RF uses 3 x AA (LR6) batteries. The batteries supplied with the unit
should last for approximately two years. When the batteries are nearing the end of their
life a 'LOW BAT' message will flash on the display.
To change the batteries it is necessary to remove the AS2-RF from the wall, to achieve this
first press the RELEASE BUTTONS located under the unit and pull the AS2-RF away from the
mounting plate by gently pulling up.
Before removing the old batteries please wait for at least 15 seconds after the last button
was pressed. Remove old batteries and ensure the L.C.D display has gone blank before
fitting the new batteries.
Replace with three new AA size alkaline batteries, ensure they are fitted correctly as
shown by the marking positioned between the battery terminals. Once batteries have
been fitted, replace the AS2-RF to the mounting plate, ensuring that the two guide lugs are
fitted into the corresponding slots in the top of the mounting plate. Now push the AS2-RF
until the release button clicks into place.
WARNING: You must ensure that the AS2-RF is always running on 3 x AA batteries and
when the battery low message is displayed it is important that they are changed as
soon as possible. This is to preserve the secondary internal reserve battery which is non-
replaceable.
For best results use alkaline batteries rather than zinc carbon batteries.
