Horstmann CENTAURSTAT 7 User Instructions

BATTERY REPLACEMENT

Your CentaurStat is battery operated. The batteries
supplied with the unit should last for approximately two
years.
When the batteries are nearing the end of their life a
BATTERY LOW symbol will flash on the display
(see diagram opposite).
Please isolate any external electricity supply to your CentaurStat before battery replacement.
Press the RELEASE BUTTON on the right hand side of the
unit and swing the front cover away from the mounting
plate by gently pulling on the right.
Remove the old batteries (with the batteries removed
your CentaurStat will retain its programme for
approximately five minutes) and replace them with
three new AA size alkaline batteries, ensure they are
fitted correctly as shown on the label positioned
between the battery terminals.
(see diagram ).
Once batteries have been fitted, offer the left
hand side of the unit up to the mounting
plate ensuring that the two guide lugs are
fitted into the corresponding slots in the side
of the mounting plate.
Now swing the right hand side of the
CentaurStat up against the mounting plate
until the release button clicks into place.
Press any button to re-activate the display
(some time adjustment may be necessary, please refer to the SETTING DAY AND TIME OF DAY section
on page 2 of this user guide.)
