10 | Installation and User Manual
The Unilux Thermostat must be installed by a trained technician. Failure to
follow these instructions carefully may result in product damage
Caution: Electrical Hazard
Equipment and wiring can cause electrical shock and equipment damage.
Disconnect power before starting installation.
If installing thermostat in standard interior wall, start with step one on this page. If installing into a North
American electrical box, skip to page 11.
When Installing Direct to Wall
2. Mount thermostat to wall
• Detach the bottom housing from the thermostat by
pulling the two pieces apart.
• Wire the thermostat according to the diagrams found
on pages 12 and 13 by passing the wires through the
bottom housing, to the top housing terminal block.
• Secure the bottom housing to the desired wall with
the provided screws. We recommend using a bubble
level to ensure the housing is straight before fully
mounting to wall.
• Reattach the top housing to the bottom.
1. Gather materials and tools
To install your new thermostat, you will need the
following tools:
• Screws and bolts (provided with the thermostat)
• Screwdriver
• Bubble Level

Installation and User Manual | 11
When Installing in North American Electrical Box
1. Check the compatibility of your electrical box
Before purchasing your new thermostat, it is important to check that the mounting holes for the thermostat will t
your electrical box. If your electrical box is a standard North American electrical box, you may encounter diculties in
installing the thermostat.
2. Gather materials and tools
To install your new thermostat, you will need the following materials and tools:
• Steel installation plate
• Plastic interface plate
• Screws and bolts (provided with the thermostat)
• Screwdriver
• Bubble Level
3. Install the Steel Installation Plate
• Turn o the power supply to the electrical box by switching o the
circuit breaker or removing the fuse.
• Remove the cover plate from the electrical box.
• Position the steel installation plate onto the electrical box so that
the holes line up with the mounting holes on the electrical box.
• Secure the steel installation plate to the electrical box using screws
and bolts provided with the thermostat.
• Check that the steel installation plate is level.
4. Install the Plastic Interface Plate and
Thermostat
• Detach the bottom housing from the thermostat by pulling the two
pieces apart.
• Position the plastic interface plate to the steel installation plate by
aligning the holes.
• Wire the thermostat according to the diagrams found on pages
12 and 13 by passing the wires through the steel plate, plastic
interface plate, and bottom housing, to the top housing terminal
block.
• Position the bottom housing onto the plastic interface plate and
align the mounting holes on the housing with the holes on the
steel installation plate.
• Secure both the plastic interface plate and thermostat to the steel
installation plate using provided hardware.
• Reattach top housing to bottom housing.

P05 - Temperature Oset
If your thermostat is in an area of your suite that is
colder or warmer than the rest of your home, you
can oset the thermostat's temperature reading to
compensate. Before you adjust this setting, you will
need a thermometer (inexpensive options can be found
in any hardware store) to measure the temperature near
your thermostat, and again in a room that feels similar
to the rest of your suite. The dierence in temperature
is what you need to oset your thermostat at. Your
thermostat can be oset +/- 5 °C or 10 °F.
