SunTouch WarmWire Installation Manual 13
STEP 6.12 If it was necessary to end a power lead at a junction box,
feed 14- or 12-gauge electrical wire from this box to the control box.
Tip: If more than one cable was installed, label the power leads
with a brief description as to which area they supply power. Use tape
to label them “Cable 1,” “Cable 2,” or “K itchen,” “Bath,” or similar. This will
make it easier to identify the leads later on. Take photos of the installa-
tion. This will provide a useful record for any future needs.
Phase 7: Install the Control
STEP 7.1 Read and follow the instructions that come with the SunStat
controls.
STEP 7.2 Refer to the wiring diagrams in this manual for different
voltages and applications.
STEP 7.3 Install the electrical b ox for the control, if this has not
already been done. Connect the power leads from the cable (or the
electrical wiring coming from junction boxes) to the “LOAD” side of
the control. Connect the incoming power to the “LINE” side of the con-
trol. Connect the sensor wires to the sensor terminals on the control.
Connect the ground leads from the system to the ground wire from
the incoming power.
STEP 7.4 Install the control into its electrical box and turn the circuit
breaker on to power the system. Test the system and control for
several cycles. It should allow the heating c ables to heat up correctly.
Note: Consider placing a loose tile over the sensor tip to simulate
warming the floor and allow the sensor to register this on the control.
STEP 7.5 Retain all instruction sheets and warranties.
Phase 8: Install the Floor Coverings
STEP 8.1 Make a Final Inspection of the Installation. Inspect the installa-
tion very carefully for evidence of damage or missing sensor(s).
STEP 8.2 Select Type of Construction. Choose the best thin-set, thick-
set, or self-leveling mortar method for the application. See Appendix 1
regarding final floor installation techniques. Consult with building pro-
fessionals and/or the factory if assistance is required.
STEP 8.3 Take Another Resistance Reading! After floor cover ings have
been installed, take resistance readings of the cable again to make sure
it has not been inadvertently damaged. This is very important to do.
Record these readings in the Cable and Sensor Resistance Log (page 6).
Phase 9: Install Insulation
Insulate under the subfloor for better performance and efficiency
of the system. Refer to the Appendix 1 for diagrams and insulation
recommendations.
Phase 10: System Operation
After all system components are in place and floor coverings installed,
briefly test the operation of the system but do not put the system
into full operation until the mortar materials are fully cured (typically
one to four weeks). See the mortar manufacturer’s recommendations
for the specific type of mortar used.
Many manufacturers of laminate and wood flooring recommend a
maximum of about 84°F (29°C) on the floor surface. Be sure to program
the control accordingly. Consult the manufacturer regarding recom-
mended floor temperatures for the flo oring being installed.
Energize the system. Operate the controls so that the system turns
on the floor-warming cable. The control will normally indicate that
power is b eing supplied to the cable. It will take some time for the
cable to warm up. Using a clamp-type ammeter (electricians normally
carry these), pull the control out of the wall and determine whether the
cables are pulling current, thus indicating they are working as intended.
Turn the system off after NO MORE than 10 minutes of operation. Do
not operate the system again until the flo or mortar is cured. Once the
flooring is completely cured, the control can be used to operate the
system for many years to come.
