Battery Replacement

When the low battery symbol flashes in the LCD display
(Fig.2, page 5), the batteries need to be replaced as soon
as possible. To replace the batteries, remove the Wireless
Programmable Room Thermostat from its back-plate. The
battery compartment is located on the main part of the
thermostat. Remove the old batteries and insert new
ones. All settings including time are maintained. N.B! If
the display ever goes blank during normal operation, the
batteries will need to be renewed with high quality
alkaline cells. The reset button should be pressed to
restart the unit. The date, time and factory pre-set heating
times will be retained and not need to be re-programmed
(assuming the back up battery has not failed).
