Location and installation of floor sensor
The optimum location of the floor sensor is described in each Warmup heater installation manual. Refer to that manual when selecting
floor sensor location.
Warmup recommends the use of conduit when installing the floor sensor. The conduit will protect the sensor and will allow easier repair
of the sensor in the case of sensor damage after flooring has been laid.
You can now power up the thermostat and begin the programming process.
Powering Up
Installation:
The thermostat should be installed inside a square 4”x4” back box with a single mud ring mounted horizontally (also called plaster ring).
For optimal performance, the thermostat should be located in an area with good ventilation. It should not be installed beside windows/
doors, in direct sunlight or above another heat generating device (e.g. Radiator or TV). The thermostat is designed for operation between
32°F to 122°F (0°C and 50°C) with relative humidity less than 80%.
Opening the thermostat
1. Separate the front housing of thermostat
2. Unscrew both closing screws (at the bottom) until they
don’t turn any further.
3. Release front housing by gripping lower half of outer
frame and pulling outwards then upwards. Place front
housing somewhere safe.
Placing the back box
1. Open the back box and create openings by pushing one
or two holes.
2. Place the rear part into the wall where you’ve chosen to
place the thermostat.
3. With 2 screws, secure the back of the Tempo to the face
of the electrical box
Connecting wires
1. Attach the sensor wires into the thermostat following the
instructions on page
2. Check to ensure that you have all the following wires connected
to the back panel of the thermostat:
- Power lead (Line 1 and Line 2 )
- Heater wire (Line 1 and Line 2)
- Floor sensor
3. Complete wiring as explained on the following pages.
4. Pull wires into the electrical box.
IMPORTANT
Ensure that multi strand wires are fully inserted into twist-on wire connectors (wire nuts) and secured tightly. Any loose strands should be
trimmed as they could cause a short-circuit.
Note: Do not obstruct the thermostat’s vents.
