Welcome to the SunTouch Mat installation video.
This video is intended to give a general overview of the installation process.
Please refer to the included installation manual and local building codes prior to beginning
any installation
The products you need for this installation are the SunTouch Mat and SunTouch SunStat.
Additional tools include a multi- meter, staple gun with 3/8Ó chisel staples, a hot glue
gun, scissors, and a hammer and wood chisel.
Before installing the mat, determine the location of the SunStat.
Make sure this location is open and accessible and not behind a closed door, in a closet,
or in a cabinet.
We recommend a dedicated power line be run to this location.
Be sure to follow all local electrical and building codes when doing this.
Drill or saw holes for conduit at the bottom wall plate.
One hole is for routing the power leads and the other is for the thermostat sensor.
These holes should be directly below the electrical box used for securing the thermostat.
For most installations, we recommend a 4x4 electrical box with a single gang mud ring.
Test the mat to ensure no damage occurred during shipping by using a digital multi-
meter.
Set the meter to 200 ohms and connect probes to the power leads.
For 120 Volt Mat connect to the White and Black leads.
For 240 Volt Mat connect to the Blue and Black Leads.
The ohm value measured should match what is on the product tag attached to the electrical
lead.
Record this value in the installation manual.
Repeat this process for each of the leads and the ground.
These values should read open or infinite as indicated by an ÒIÓ or a dash on the
ohm meter.
Next test the thermostat sensor.
The sensor is included with the SunTouch SunStat.
Set the multi-meter to 20,000 ohms.
Connect the probes to the leads of the sensor.
This value will vary based on the temperature of the room.
When the sensor measures 75-degrees the resistance reading should be approximately 10,000-ohms.
Before laying the mat, be sure to thoroughly clean the floor, removing all debris.
Feed the power leads from the mat up to the control location.
Do the same with the sensor.
A factory splice connects the cold lead to the Mat.
It is important not to bend this connection.
Depending on the thickness of the mortar used, it may be necessary to chisel out a portion
of the subfloor to recess the factory connection.
Hot glue this into place.
The Mat can be manipulated to fit any type of area using a combination of roll-overs
and turns.
The wire can also be removed from the mesh entirely to cover odd shaped areas using a
fill-in technique.
Secure the mat in place with the use of a staple gun or hot glue.
Staple only the orange mesh.
Do not staple the blue heating wire.
Do not route Mat under vanities or permanent fixtures.
Stay 4 - 6Ó away from walls, vents, and the wax ring on toilets.
Once the end of the Mat has been reached, attach the end splice to the floor with hot
glue.
It may be necessary to chisel a small portion of the floor depending on the thickness of
The heating cable CAN NOT be cut or shortened.
In most cases excess Mat can be routed around the perimeter in the 4-6Ó gap, staying at
least 2Ó away from other installed Mat, built-ins, and walls.
Once the Mat is secure, itÕs time to install the SunStat sensor.
Position the sensor parallel between the heating elements.
DO NOT cross over the heating wire.
Hot glue the sensor to the floor.
At this time, perform another resistance check of all components.
Record these values in the installation manual.
We recommend using a 3/8Ó thick polymer modified thinset.
A self-leveling mortar can be used when installing under laminates, hardwood, carpets etcetera.
Regardless of the floor covering, the Mat must be fully encapsulated in a mortar bed.
To install the SunTouch SunStat thermostat, first remove the face plate from the base.
Take caution not to bend the internal connection pins.
It may be necessary to shorten the leads from the Mat, however, be sure not to remove the
ID tag.
Connect the Load leads to the Mat and the Line leads to the power in from the breaker.
Connect the sensor to the sensor terminals.
Be sure that the ID tag from the mat is left in the electrical box for future reference.
Once all connections are made, secure the base to the electrical box using the included
screws.
Reattach the face plate to the base, taking care not to damage the internal connector
pins.
At this time, briefly turn on the SunStat to test the system.
Do not leave the thermostat on for an extended period of time.
Doing so may compromise the thinset during the curing process.
You have now completed your SunTouch electric floor heating mat installation.
We are confident you will enjoy your new warm floor for many years to come.
