SunTouch Mat Do It Yourself Manual
INSPECT MAT, CONTROL, and SENSOR
STEP 2.1
Remove the Mat, SunStat control, and SunStat sensor from
their packages. Inspect them for any visible damage and
verify everything is the correct size and type according to
the plan and the order. Do not attempt to install a damaged
product.
STEP 2.2
Record the product information in Table 4. Give this
information to the homeowner to keep in a safe place.
The mat model number, serial number, voltage, and
resistance range are shown on a nameplate label attached
to the power leads, as well as the marking “(x)-FOR INDOOR
FLOOR HEATING APPLICATIONS”.
Do not remove this nameplate label. The electrical
inspector will need to see this.
STEP 2.3
Use a digital multi-meter set to the 200 or 2000 (2k)
range to measure the resistance between the conductors
of the mat power leads. Record these resistances in Table 4
under “Out of the box before installation”.
The resistance should measure within the resistance range on
the nameplate label. If it is a little low, it may be due to low
air temperatures or meter calibration. Consult the factory if in
doubt.
WARNING: To prevent the risk of personal injury
and/or death, make sure power is not applied to the
product until it is fully installed and ready for final
testing. All work must be done with power turned off
to the circuit being worked on.
Record the information from
the nameplate label into the
Mat and Sensor Resistance
Log. Leave the nameplate label
attached to the power leads for
later inspection.
Press the test lead tips to the Black and White (or Blue for 240 VAC) power lead wires.
This reading should correspond to the factory resistance range on the nameplate label
attached to the Power lead.
Readings between the Black and Ground and the White (or Blue for 240 VAC) and
Ground power lead wires should measure “open”, or “O.L”, or the same as displayed when
the test leads are not touching anything.
