Installation Instructions

• 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 the cover and the 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, and 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 the LCD display is ON.

Do not install the battery before power is applied.

• Remove the battery from the back panel by sliding it to the left and out from its white retaining clip and mounting it in a black holder on the 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.
• The ‘+’ engraved on the battery should be visible (pic. 4).

Be careful – the top clip of the battery holder is fragile.

• Reassemble the front and back covers.
• Connect at the top first then at the bottom
