It is recommended to mount the thermostat between 1.5 & 1.8
meters from the floor where possible.
Separate the base from the cover by pressing the tongue (pic.1).
Gently disconnect the quick connector between cover and base
(pic.2)
Line the back panel up against the wall and drill the appropriate
fixing holes (pic.3).
Insert screws so they extend approx. 3/16" (3 mm) from the wall.
Align the back panel against these screws, pushing it forward,
allowing it to slide downwards to lock into position.
Make electrical connections to terminals on the back panel. Refer
to the “Wiring Connections” section.
Reconnect the quick connector.
Change the JUMPERS position according to the system
configuration. Refer to the “Jumper Configuration” section.
Attach the cover to the base, first the two shafts and then the
spring.
Connect 24Vac to the thermostat; verify that LCD display is ON.
Do not install battery before power is applied.
Remove battery from back panel by sliding it to the left and out from
its white retaining clip and mount it in black holder on front panel;
insert it from the top, gently pressing downwards until it snaps into
place and is held under the top clip of the holder.
