Important General Considerations
Your Floor Covering Choice
How High Is The Floor
WarmlyYours’ Floor Heating Systems are most commonly installed under stone
or tile floors. If you will be installing another floor covering, please make sure you
embed the WarmlyYours Floor Heating System in a minimum 3/8” of thinset or
self-levelling cement before you install the final flooring material.
While the Warmly Yours Floor Heating System is only 1/8” inch thick, it is a
requirement to have a layer of thinset cement a minimum of 3/8” thick from the
surface on which it rests to the bottom of the floor covering. This and the final floor
covering should be calculated in the other aspects of your space such as doors,
thresholds and other permanent fixtures.
Insulation
Are you installing on a concrete slab? Consider adding a layer of insulation. For
more details, see page 3.
Professional Electrical Installation
The installation of electrical systems presents risks of fire and electrical shock
which can result in personal injury. Caution should be taken to guard against
each such risk. Only a qualified electrician should connect the Floor Heating
System to the control device and to the electrical circuit in accordance with the
National Electrical Code and Local Codes. A tile setter, a flooring contractor, or a
qualified Do-It-Your-selfer can install the Floor Heating System in the floor before
the electrician connects it to the electrical circuits.
The Safety of GFCI
The WarmlyYours Floor Heating System must be connected to the electrical system
via a Ground Fault Circuit Interrupter. This GFCI feature may be incorporated in
the thermostat’s functionality or it can be provided by the electrician, either at the
circuit breaker or at the line’s end, near the control device.
Protect Your Investment
To avoid damage to the Heating Element during the installation, care must be
taken so that tools with sharp edges or points are not dropped or used carelessly
on the Heating Element. Minimize walking on these elements and remember
that when rising from a kneeling position, metallic toecaps may exert too much
uneven pressure on the Heating Element. We recommend covering the exposed
areas with thick pieces of cardboard or carpeting to reduce the risk of damage.
Nothing On Top
The WarmlyYours Floor Heating System must not be installed under cabinets or
plumbing fixtures that will be permanently installed and attached to the floor. Builtin cabinets and other furniture or fixtures with solid bases must not be placed on
the heated portion of a WarmlyYours system. Additionally carpets or area rugs
thicker than 3/4” should be avoided, as they act as an insulator over the heated
area, reducing the efficiency of the installation.
Testing 1, 2, 3 Testing
If there are only two things you remember about this manual they should be: Do
Not Cut The Heating Element and Test the Resistance of the Floor Heating
System Before, During and After its installation.
1. Before-Test the Ohm resistance of each Heating Roll once it has been removed
from the box to assure that it was not damaged in transit.
2. During- Test the Ohm resistance of each Heating Roll once it has been placed
and secured to the subfloor to verify the Heating Roll was not damaged during
the installation process. The next step will be to encase the entire system in
thinset cement. Once this is done, it is very difficult to remove the product.
3. After- Once the floor covering is complete, test again to verify that the Heating
Element was not damaged during tile setting.
An Ounce Of Prevention
Prepare your subfloor as you would for any standard installation. We recommend
that you follow the standard guidelines set forth by the Tile Council of America.
Special consideration should be paid to the removal of any nails, staples or other
objects that may damage the Heating Element.
Beware Of Sharp Objects
Nails or screws may not be installed close to the Heating Elements and cold lead
wires. At no point in time should walls or permanent fixtures be installed on top
of the heated area. It is important to keep track of the Installation Plan so you or
a future owner will know where the Heating Roll is located. Indicate the location
of an in-floor sensor on your Installation Plan if one was installed.
9 Times Out Of 10
The easiest way to solve a problem is to pick up the phone and call us at
(800) 875-5285. While we encourage you to read through the entire manual
and to double check the trouble shooting section first, we want your installation
experience to be trouble free.

Understanding The System Components
The Heating Roll
A. Heating Element
B. Fiberglass Mesh
C. Polyblend Thread
D. Cold Lead Wire (white)
E. Cold Lead Wire (120V yellow
or 240V red)
F. Factory Splice
G. Floor Sensor (optional)
Relay Contactor or Power
Modules (not required for all
systems)
Systems installed in large spaces will most likely require
a Relay Contactor or Power Module(s) in addition to the
control device to operate properly. The Relay or the Power
Modules may be located in the same vicinity as the control
device. If your system will be using this option, all, cold
leads will be connected to the relay contactor or power
module and not directly to the control device.
Heating Roll(s): Types and Sizes
Secondary Teflon
Insulation
Metal Braiding
Connected to Ground
Multi Strand
Conductor Wire
Primary Teflon
Insulation
Roll(s) are rated at 15-watts per square foot and vary in
length. Each roll is designed to draw a specific amount
of electricity and therefore produce the proper amount
of heat based on its length. For this reason the length of
the roll(s) can never be shortened to make a proper fit.
Your Installation Plan has been designed to specifically
accommodate your space. The same is true for rooms that
have multiple rolls. Multiple rolls are never wired to each
other. Each roll is wired in parallel to the control device or
relay contactor.
Working With The Heating Roll(s)
The Heating Element
The Heating Element consists of a copper alloy resistance wire covered by Teflon™ insulation. A braided metal
surrounds the primary Teflon™ insulation and serves as ground sheath, before a second layer of Teflon™ insulation,
serves as the outer shell. The Heating Element (A) is sewn in a serpentine pattern to a flexible Fiberglass Mesh (B)
with a polyblend thread (C). The Fiberglass Mesh is designed to keep the Heating Element evenly spaced throughout
the roll. The two cold lead return wires (D & E) are factory installed at each end of the Heating Roll and must run back
to the power supply along the perimeter of the heated space. One return power lead (D) is marked with WHITE marks
and is 26-feet in length, the other return power lead (E) is marked YELLOW for 120V or RED for 240V and is 13-feet
in length. The two leads are spliced to the Heating Element (F) at the factory. If necessary these lead wires may be
cut short or even extended.
Floor Sensor (not required for all systems)
Systems using a SmartStat Programmable Thermostat or EasyStat require a Floor Sensor (G). This Sensor is
embedded in the floor and monitors the floor temperature. The Floor Sensor should be centered in between 2 resistance
wires leaving approximately 1” on either side and extend about 6” into the heated area. Avoid placing the sensor in an
area affected by a draft, a radiator or the sun. Must be installed if using a thermostat. Some people choose to install a
second (Backup) sensor. For an additional cost you may purchase a second sensor.
2
The roll(s) that make up your system have been selected to
fit into your floor plan. The Installation Plan shows precisely
where each roll starts and ends. The “Lead Wires” on
each roll are designed to travel back to the control device
location. These wires do not heat. All connections are made
at this point. While it may be required to cut and alter the
“Fiberglass Mesh”, the “Heating Element” must stay intact.
Page 6 shows in detail how to make the necessary turns to
install your Floor Heating System.
Separating The Heating Element
From The Mesh
During the installation you may need to separate the Heating
Element from the Fiberglass Mesh. This can be done with
small scissors provided the Heating Element is not cut and
the shielding is not nicked or punctured. It will be necessary
to do this when releasing the Heating Element to make step
turns and position it in a “Free Form” space.
Understanding The System
How The System Works
You can feel the heat of a campfire even though you are
not directly above it. Radiant energy transfer is caused by
a warm surface (the campfire) giving up its heat to a cooler
surface (your body). This radiant energy travels through
space without heating the space itself. It only turns into
heat when it contacts a cooler surface. By transferring this
heat to all of the objects in the room, the heat slowly moves
to warm the air which starts to rise.
Proper Heat Dissipation
All radiant heating systems rely on a “Heat Bank”. The heat
moves from the source (Heating Element) into the Heat
Bank (thinset) and spreads out and warms the floor without
creating an excessively hot spot. In the WarmlyYours
Floor Heating System the thinset and/or self-levelling
cement acts as the Heat Bank. It is important to follow the
installation guidelines to create a proper Heat Bank.
Insulation – Proper Heat
Retention
When WarmlyYours floor heating systems are installed on
a concrete slab, we strongly recommend adding a layer
of insulation to the slab prior to installing the radiant floor
heating system.
While WarmlyYours systems provide up to 25% more
heating power per square foot than the nearest competitor,
the slab will always act as a “heat sink.” Some of the
heat that would otherwise be transferred to the flooring
surface will remain in the slab, causing the floor’s surface
temperature to be considerably lower. This is true with any
floor heating system.
This leads to greater efficiency and therefore faster warm
up times, higher expected surface temperatures and lower
energy usage. The floor will have the capacity to warm
to a comfortable temperature, and in some cases can be
employed as the primary heat source for that room.
Control Device Options
Option 1: Programmable
Thermostat
Securing The Roll(s)
The SmartStat has an in-floor sensor and a digital display
that indicates the exact floor temperature. It also features a
manual set-back to a “high” and a “low” temperature level,
and a built-in GFCI. The programmable function allows you
4 setting changes for each day of the week. Its maximum
capacity is 1800 watts at 120 VAC or 3600 watts at 240
VAC . Any floor requiring more power will need to be zoned
with more than one SmartStat™ and a Relay Contactor or
with a Master Thermostat and a Power Modules.
Once the roll(s) is fitted into the space, it needs to be
secured to the subfloor to prevent movement during the
installation of the floor covering. The options for securing
the roll(s) are discussed in detail on Page 12. Regardless
of the method you choose, it is vital that the integrity of
the Heating Element be maintained. Staples should never
cross, pierce or nick the Heating Element.
Protecting The Heating Element
It is vital that proper care be taken to insure that the
Heating Element is not damaged during the installation of
the system or by the floor covering. A thorough preparation
and detailed inspection of the subfloor will assure that any
and all objects that may damage the Heating Element are
removed prior to installation. Heavy gauge cardboard or
carpet scraps should be used to protect the system from
traffic during the flooring installation.
Never Cut The Heating Element
The key to the system is the uninterrupted flow of
electricity through the Heating Element.
Option 2: EasyStat
Non-Programmable Thermostat
The EasyStat™ has an in floor sensor just like the
SmartStat™, but requires no programming. Just enter the
floor temperature using either Fahrenheit or Celcius. It is
equipped with a GFCI and is available in 15 amps at both
120 volt and 240 voltages. A floor requiring more power
will need to be zoned with more than one SmartStat and
a Relay Contactor or with a Master Thermostat and Power
Modules.
Option 3: Comfort Regulator
The Comfort Regulator has an ON-OFF switch and a
manual dial control that allows you to increase or decrease
the floor temperature. The Comfort Regulator has a built-in
GFCI. Its maximum capacity is 1800 watts at 120 VAC or
3600 watts at 240 VAC . Any floor requiring more power will
need to be zoned with multiple SmartStats or use a relay
contactor or power module.
When installed on top of a concrete slab without insulation,
it is generally accepted that a radiant floor heating system
will take the chill away from the floor and provide a small
amount of warmth.
Adding insulation on top of the slab and beneath any floor
heating system will allow a greater percentage of the heat
generated to transfer to the flooring surface.
3
Items Needed For The System Installation
System Components From WarmlyYours
Circuit Check
1. The Customized Installation Plan (or layout).
This device is provided in every order from WarmlyYours and is a continuity checker that
you connect to the cold lead wires before installation of the flooring material.
2. Heating Roll(s) (15-watt/ sq. ft.) If multiple rolls are connected to the same control
device, they must be of the same voltage type and wired in parallel.
3. Control Device (one of the following):
• SmartStat™ Programmable Thermostat
• EasyStat™ Non-Programmable Thermostat
• Comfort Regulator
4. You may also have a relay contactor or power module if your system is being installed
in a large area.
IMPORTANT - Cross check the items you received against the packing
list and the materials list on the installation plan to ensure that the roll
length(s) and thermostat type(s) are an exact match.
Ground Fault Circuit Interrupter
GFCI or ‘GFCI-breaker’ indicating its capacity if not incorporated into the control device
you are using. This is a built-in feature of the SmartStat Programmable Thermostat,
EasyStat or Comfort Regulator.
Digital Ohm Meter (multi-meter)
Test the Heating Roll(s) before, during, and after the installation. A digital meter is strongly
recommended because of the precise measurements needed.
Electrical Housing Boxes/Switch Plates
All control devices except a Relay Contactor fit into a deep single gang box. If a double
gang box is used it will need to be fitted with a single gang mud ring. We strongly
recommend a double gang box with a single gang mud ring as it provides more room to
place all the wires.
Electrical Conduit
Local electrical codes often require the power leads be inside a metal or plastic conduit
when running through the wall from the Heating Roll to the control device. When using
an in-floor sensor, if local code requires the low voltage sensor wire be housed in conduit,
it must use a separate conduit from the power leads(high voltage).
A Permanent Marker And Tape Measure
To measure and mark Installation Plan points onto the prepared subfloor as well as where
to alter the Fiberglass Mesh of the Heating Roll(s).
Utility Scissors
Scissors are the best tool to trim and alter the Fiberglass Mesh of the Heating Roll and to
separate any lengths of Heating Element from the Mesh. Never cut the Heating Element.
Hot Glue Gun, Double-Sided Tape And Or Stapler
Double Check Your Dimensions
Check and verify that your plan has the correct room dimensions.Your order consists of
the exact amount of material required to complete your project. If the measurements of
your space have changed, this will affect how much product is required and how it will be
installed. Once the Heating Roll is cut into panels, it cannot be returned. If you have any
discrepancies or questions call, WarmlyYours at (800) 875-5285.
4
Use these tools to affix the Fiberglass Mesh portion of the Heating Roll to the prepared
subfloor before covering with thinset cement. Beware that misuse of a stapler can cause
damage to the Heating Element. NEVER staple across or on top of the Heating Element.
Off-Cuts Of Cardboard Or Carpet Scraps
To protect the Heating Element during the installation.

One Good Turn Deserves Another
The complimentary Installation Plan
provided by the WarmlyYours team is very
important. It shows the recommended
placement of your Heating Roll(s) for
safety and optimal efficiency. The plan will
also serve as the reference for any future
inspections or floor work that needs to be
performed.
The Heating Element of the WarmlyYours
product is sewn in a serpentine pattern on
to lengths of Fiberglass Mesh forming a
roll. It is quick and simple to cover large
areas.
Your plan shows you where any
modification is necessary. These are
all easily done by cutting through the
Fiberglass Mesh material (NOT the
Heating Element), see Photo A , so that
the roll is in two or more, moveable -but
connected- pieces which are called
“Panels” see Photo B. These panels can
be angled, turned or completely flipped
over in order to cover the space.
Photo A
Make a single cut through the entire width
of the Fiberglass Mesh. Never Cut the
Heating Element.
Flip Over Turn (90°)
Photo C
By cutting Only The Mesh (see Photo A),
you can move the remaining section of
the Heating Roll in a new direction. By
doing this, you are creating what are now
referred to as “panels.” (see Photo B). This
is the first step in any turn or alteration of
the Heating Roll(s).
A turn is indicated on the Installation
Plan by an arc with an arrowhead.
By examining the
relationship between
two panels, you will
determine the type of
turn needed.
To release the required amount of Heating
Element for a free form area first make the
two straight cuts and then carefully cut the
polyblend thread and remove it.
6
U Turn (180°)
Make a Straight cut and then slide the
balance of the panel around and head
back in the opposite direction. Your plan
will tell you exactly where to make your
cut.
Photo B
The resulting sections are called panels.
To cover very small or odd shaped
areas, the Heating Element is used in
“Free Form”. A section of the Fiberglass
Mesh is removed in order to release an
appropriate length of Heating Element
to fill the space, see Photo C. This “free”
wire is placed in areas not reached by the
main Heating Elements of the panels. It is
also used to make “step turns” possible.
Always maintain 2” spacing in all free form
and step turns.
Cut & Turn
Make a Straight cut and flip the section
over so that the Heating Element is
now above the Mesh and continues
in a perpendicular direction. Use the
Installation Plan to determine the exact
location for the cut.
One Good Turn Deserves Another
Free Form
Free form spaces are filled with loose
lengths of Heating Element.
A wavy line with an arrow will appear
on the Installation Plan to indicate the
area that needs to be filled. This symbol
is accompanied by a unit of
measure in a circle that will
indicate the amount of Fiberglass
Mesh to be removed. (See Page 5, Item F
on Installation Plan.)
Once the polyblend thread is trimmed,
the Heating Element separated and the
Fiberglass Mesh removed, position the
Heating Element by hand and secure it
to the floor with Hot Glue or Tape. Try to
maintain the 2 inch spacing similar to the
spacing on the Heating Roll(s).

This is the most popular way to do a step
turn because it keeps the Heating Element
under the Fiberglass Mesh offering
some protection during floor covering
installation.
Cut and remove the amount of Fiberglass
Mesh indicated in the circle and make
a 180° flip turn. The released Heating

Finish
Working Around
Obstacles
Special circumstances will require the
Heating Element to circumvent an
obstacle. The released Heating Element
is not needed to fill an area but to simply
continue the circuit.
Experience Is The key
As you begin to work with the Heating
Panels, you will become more comfortable
with the product. The ultimate goal is to
keep even spacing of the Heating Element
and the integrity of the electrical circuit.
Finish
Some installations will require a Heating
Panel to be placed with the wires facing
up. We recommend that at the next turn
the panel should be flipped over so that
the Fiberglass Mesh sits on top of the
Heating Element.

Important General Considerations
Note for the System Installer
UNBELIEVABLY IMPORTANT INFORMATION
The most important consideration is to maintain the
integrity of the Heating Element. This can be easily done
by following these simple rules.
Provide the homeowner with a copy of the Installation Plan provided to
you by WarmlyYours.
This will help you and future owners of the home. The plan should indicate where the
WarmlyYours Heating Roll(s) is installed, the location of the control device and the
amperage of the system. If a sensor is used, indicate its location on the plan. The electrician
should put the code labels (UL) from any Heating Roll used in a convenient place such as
the circuit breaker box. The labels should have Ohm resistance readings written on them.
These are a useful reference for future inspections and possible troubleshooting.
1. NEVER CUT the Heating Element.
2. NEVER CUT the Heating Roll(s) to make it shorter.
3. NEVER fold or position the Heating Element so that it
overlaps itself or other wires. This will cause dangerous
overheating.
4. NEVER run the Cold Lead Wires or Sensor Wire across the
Heating Element.
5. NEVER place built-in cabinets and other furniture with solid
bases on the heated portion of the floor.
6. ALWAYS make sure the system is inspected and the Ohms
tested before, during and after installation.
7. ALWAYS make sure everyone involved in the installation is
aware of the care needed to protect the Heating Element
from damage.
8. ALWAYS maintain consistent spacing when positioning the
Heating Element.
9. NEVER connect two Heating Rolls to each other (in series).
Only connect them in parallel to the same control device.
10. A dedicated circuit must be provided for the system.
11. Tiles will only be warm where the heating wire is installed.
If there is no heating wire directly under the area, it will not
be warm.

The instructions in this manual must be observed when installing the WarmlyYours Floor
Heating System. Failure to follow these instructions may inhibit optimal performance of
your Floor Heating System and void the system warranty. A tile-setter, flooring contractor
or qualified Do-It-Yourselfer can install the WarmlyYours Heating Roll(s). However, a
qualified electrician must complete the electrical connections of the system to the main
electrical circuit in accordance with the National Electrical Code and your local codes. We
trust that your installation goes well and that you enjoy your warm floors! Always be aware
of your plan!
This is a Test - Not Only A Test
DO NOT SUPPLY THE SYSTEM WITH ELECTRIC
CURRENT
All testing is done with a digital Ohm meter. Supplying the system with a 120 volt or 240
volt electric current before the installation is complete is not needed to test the system
Taking The Ohm Readings
The electrical resistance of the Heating Roll(s) must be checked before you start, and
monitored throughout the installation process to ensure there has been no damage
causing shorts or breaks. We recommend at least three readings be taken:
1. Before starting installation.
Go By The Numbers
The Ohm resistance should be measured from the inner core of the yellow (120V), or
red (240V) lead wire at one end, to the inner core of the white lead wire at the other end.
Make sure that the probe of the Ohm meter does not touch the tinned sheath wire at
either end. Even your body’s electrical resistance can affect the reading if you touch
the meter poles. Do not hold the wires onto the probes with your fingers. A digital
meter is easier to use and strongly recommended. It is wise to verify that the batteries of
the Ohm meter are good. Set your Ohm meter to measure resistance in the range of 0
to 200 Ohms.
2. After securing the Heating Roll(s) in place on the subfloor.
Four (4) Ohm Readings should be taken for each roll of WarmlyYours TempZone at each
stage of the installation and recorded in the table below.
3. After installing the flooring surface above the Heating Roll(s).
1) Core to Core - This is the reading between the two inner conductors on the lead wires.
The Ohm resistance measurement should be within +/- 15% variance of the original
measurement indicated by the factory on the UL label.
2) Sheath to Sheath - This is the reading between the two outer ground sheaths on the
lead wires.
Store The UL Labels
3) Core to Sheath START Lead - This is the reading between the inner core and the
outer ground sheath on the lead wire at the beginning of the roll. This reading should
be infinity.
The electrician should carefully mark the initial Ohm reading taken onto the UL label(s) from
the Heating Roll(s), then place the labels in a convenient place such as the circuit breaker
box. These are a useful reference for future inspections and possible troubleshooting.
Should the initial Ohm reading be outside the 15% +/- variance, refer to the electrical
trouble shooting section on Page 14, or call Technical Support at (800) 875-5285.
4) Core to Sheath END Lead - This is the reading between the inner core and the outer
ground sheath on the lead wire at the finish point of the roll. This reading should be
infinity.

Electrical Planning
Prepare The Subfloor
Mark The Floor
Mark The Roll
The power supply to the Floor Heating
System and the control device will be located
at the same point in the room and indicated
on your plan. If this location has changed, call
WarmlyYours to determine if this will require
a new Installation Plan. The yellow (120V)
or Red (240V) lead wire is 13’ long and the
white lead is 26’. You can relocate the control
device as long as your leads reach the new
location.
Inspect the subfloor surface carefully.
Remove all debris and grind any sharp edges
of cracks. It is important to remove any sharp
edges or pointed objects that might damage
the Heating Element.
The thermostat requires a deep single or a
double gang box with a single gang mud ring
and should be positioned in a convenient
place for easy access. From the gang box,
two sets of wires will go to the floor:
Set 1) The 120-volt or 240-volt cold lead
wires that power the system
Set 2) The low voltage sensor wire if a
SmartStat or EasyStat thermostat is
being installed.
Some local electrical codes require the
low voltage and/or 120-volt wires above the
floor to be installed in conduit. The low
voltage sensor wire must not be placed in
the same conduit as the 120-volt or 240volt power supply. The portion of the cold
lead that is installed in the floor will be directly
covered with thinset cement or a flooring
adhesive.
All lead wires will travel back to the control
location (either directly or through a Relay
Contactor) AND MUST NOT CROSS OR
COME IN CONTACT WITH THE HEATING
ELEMENT.
Cement Subfloors Insulate for Heat Retention
We strongly recommend adding a layer
of insulation to the concrete slab prior to
installing the floor heating system. Secure the
insulation to the subfloor before installing the
floor heating system.
Expansion
joints
require
special
consideration. Heating panels cannot cross
these joints and your Installation Plan should
accurately indicate all joints. If your Installation
Plan does not match your subfloor, contact
Warmly Yours to have a new plan designed.
Plywood & Cementboard
Subfloors
Remove all debris, staples and nails. Repair
any loose boards and sand the edges of
any boards that are at different elevations.
Although you may lay the Floor Heating
System directly on top of the wood subfloor,
some installers prefer to avoid direct contact
by first applying a 1/8” to 1/4” layer of thinset
cement and letting it dry. Both methods are
acceptable.
Mudbed Subfloors
The Heating Roll(s) are always installed
on top of the Mudbed in the thinset used to
adhere the tiles.
It is advised to prepare the subfloor as you
would for any conventional installation along
the Tile Council of America Guidelines.
10
Using a suitable pen, and referring to the
Installation Plan provided, mark off areas on
the floor where permanent/heavy fixtures will
rest. (Cabinets, toilet bases,etc.)
Mark the position of the sensor (if one is to be
used) as well as the planned route of the cold
lead wires and sensor wire (if used).
Indicate where the Heating Roll(s) will need
to be cut and the Fiberglass Mesh will be
removed to customize the roll(s) with flips,
turns and where freeform spaces will be
located as indicated on your Installation Plan.
Refer to Page 6 to understand how to
customize and alter the Heating Panels with
flips, turns and freeform spaces.
Refer to Page 7 to develop an understanding
of where the Heating Panels need to be
placed in relation to permanent fixtures and
trafficked areas.
On the Heating Roll(s), mark the location for
the planned cut and turns and the length of
the free form cuts. Do this from the beginning
to the end of the roll; this is the last time
you can make sure that the total of all panel
lengths on your Installation Plan is the same
as the length of the roll you received.
If there are any changes or discrepancies
with the Installation Plan, you will be able
to choose different locations for the cut-&turns, but the reference marks on the roll will
help you to always know if you are effecting
turns a few inches ahead-or-behind what was
designed on the Installation Plan. Remember
that if you extend 3 panels by 4”, at the end
you will be missing a 1’ length of Heating
Roll. Plan any deviation from the Installation
Plan accordingly.

STEP 8
Check Roll(s)
Place Roll(s)
IMPORTANT
Fit The Roll(s)
Unpack the Warmly Yours Heating Roll(s) and
check the Ohm resistance between the two
conductor wires to ensure there is no break or
short in the cold lead conductors or the heat
resistance wire. Each Heating Roll is labeled
with its size and Ohm resistance.
Dry fit the Heating Roll(s) according to the
Installation Plan and your floor markings.
This will give you an opportunity to make any
adjustments in roll location. Be careful not to
fold the roll sharply as any sharp kink may
damage the Heating Element.
Careless use of tools and excessive
traffic during the next few steps is
the leading cause of damage to the
Heating Element. Never drop or bang
a tool on the Heating Element.
If your installation uses two or more rolls, label
each one with the corresponding roll number
(ie.“R2”, R3, etc.) found on the Installation
Plan. Be sure to mark the UL label on the
roll itself and the ends of both cold leads
so that subsequent testing will allow you to
determine which roll your Ohm readings are
from. Record the readings from each roll on
the Ohm log on Page 9 of this manual.
Ohm Reading #1
The Ohm resistance measurement should
be within +/- 15% variance of the original
measurement indicated by the factory on the
UL label. If your readings are outside of this
range, refer to the electrical trouble shooting
section on Page 14, or contact Technical
Support at (800) 875-5285.
Refer to Page 1 on the key areas to cover
and avoid.
When fitting the Heating Roll(s), the Heating
Element can be either above (“wires up”) or
below (“wires down”). We designed your
Installation Plan to assure that most Heating
Panels will be installed wires-down, with the
Heating Element below the Fiberglass Mesh.
Application of thinset cement will be easier
when the Heating Element is below the Mesh
and the Mesh offers some protection during
the floor installation. Only after a 90° flip-over
turn will the heating Element be above the
Mesh, and we recommend that at the next
free-form opportunity you reverse to a wiresdown position.
Minimize walking on the Heating
Elements and remember that when
rising from a kneeling position, toecaps
may exert too much uneven pressure
on the elements.
We recommend the use of thick scraps
of cardboard or carpeting squares to
reduce the risk of damage.
Fit the Heating Roll(s) one panel at a time.
Execute the cuts-&-turns according to your
Installation Plan and modify the roll into
successive and interconnected panels
shaped to cover the planned area.
Use the instructions on Pages 6 & 7 to make
the proper turns and fill the freeform spaces
with the length of Heating Element indicated
on your Installation Plan.
When customizing your Heating Roll(s), cut
only the Fiberglass Mesh. Never cut the
Heating Element when fitting the panels.
Follow the guidelines on Pages 6 & 7.
Make sure that everyone involved
in the installation or performing
other work in the space during the
installation process is aware of the
extra care needed to protect the
Heating Element.

STEP 9
STEP 10
STEP 11
STEP 12
Secure The Panels
Check Spacing
Install The Sensor
Affix Lead Wires
Once you have determined that the Heating
Panels will fit in accordance with the
Installation Plan and that the cold lead wires
will travel back to the power supply without
crossing over the Heating Element, you can
start to secure the Heating Panels to the
subfloor.
Secure the Heating Panels in the free form
areas. Heating panels must not be laid too
close together. Check the maximum distance
between wires inside the Fiberglass Mesh
and maintain at least 60% of this distance
when positioning free form areas.
If you are installing a Comfort Regulator go
to Step 12.
We recommend using a hot melt glue gun
with high temp melting glue sticks. Glue can
be placed on the Fiberglass Mesh and the
Heating Element as needed to secure all of
the panels to the subfloor. (Double stick tape
is also suitable for securing the panels)
While a staple gun will work on wood
subfloors it is vital to avoid any contact
between staples and the Heating Element.
Spacing the wires too widely may create cold
areas. Remember heat will travel only 1”
from each wire.
Never overlap wires. Heating Panels that
overlap will cause dangerous overheating.
Cold lead wires that overlap the Heating
Panels may cause a short circuit.
Ensure that the yellow (120V) or red (240V)
and the white (cold) power leads can reach
the control device without overlapping other
wires.
If you are installing a Thermostat, the
floor sensor should be placed below the
Fiberglass Mesh centered between the
Heating Element and held in place with a
little thinset or hot glue.
Check the Ohms reading of the sensor wire
before and after installation to make sure it
has not changed. Most sensor wires have
Ohms readings of 8,000 to 20,000 and
your OHM meter must have a 20 kohm
setting for this measurement.
The sensor wire cannot cross any Heating
Element or lead wire. It must project at
least 6” into the heated area. The sensor
and its wire should be covered directly with
thinset cement or adhesive.
If the local electric code in your area
requires low voltage wires behind the
wall to be installed in conduit, it should be
placed in a separate conduit than the
one used for the higher voltage cold
lead wires that power the system.
12
The two cold lead (non-heating) power wires
are 1/8” thick and are factory installed at the
ends of the Heating Roll. These cables may
be shortened or extended, but remember that
they are constructed like coaxial cables with
a sheath around the core conductor. The
sheath needs to be grounded at the control
end.
The yellow or red cold lead is approx. 13
feet long and is generally considered the
“Start” of the Heating Roll. The white cold
lead is approx. 26 feet long and is generally
considered the “End” of the Heating Roll.
The return cold lead wires should be placed
above the subfloor, along the side of the
Heating Panels. Secure them with suitable
tape or hot glue before the thinset or floor
adhesive is applied over the cables.
The return cold lead will go into the conduit
for electrical wiring flush with the wall. Use
plastic bushings. .

Ohm Reading #2
Embed Elements
STEP 15
Choose This
FOR TILE & STONE FLOORING
CHOOSE 1 OF THESE:
1. Single Layer Method
Apply a layer of 3/8” (minimum) thinset
cement or adhesive over the Heating
Roll(s).
Lay the tile or stone directly into that
layer of thinset cement.
OR
Take another Ohm reading to check the
element for damage.
Record readings on Page 9 of this guide.
A ‘good’ reading is within 15% variance +/- of
the factory reading which is on the UL label.
If your system uses two or more Heating
Rolls, make sure you have labeled the cold
lead wires with their roll number.
Keep in mind that the next step is to embed
the Heating Roll(s) in a layer of thinset
cement. NOW is the time to discover any
problems with the Heating Element continuity.
Once the thinset is applied it becomes much
more difficult to repair any damage. Before
embedding Heating Roll(s) in thinset attach
the Circuit Check to the cold leads
Embed the Heating Roll(s) over the subfloor
with a single or double layer of a “modified”
thinset cement. Acrylic, latex or polymer
“modified” thinset cement are all examples
of thinset applications that will work well.
Make sure that your adhesive is compatible
with your flooring material. Contact
the adhesive manufacturer or the Tile
Manufacturer to find out.
Careless use of the trowel can cause damage
to the Heating Element. Never drop or bang
a tool directly on the Heating Element.
A single or double layer method may be used
over any subfloor (plywood, cement slab,
concrete backer board or mud bed). These
methods are suitable for any stone or tile
floor covering.
If your floor covering will be carpet, vinyl
or laminate you will need a two stage
application to produce the smooth surface
for these types of flooring.
2. Double Layer Method
Embed the Heating Roll(s) in a skim
coat of thinset or adhesive completely
covering the Heating Element and the
sensor wire.
Apply a second layer of thinset or
adhesive and lay the tile as usual. A
required minimum total for both layers is
3/8” of thinset or adhesive.
In choosing between the single layer or
the double-layer method you may want
to consider the following: We do NOT
recommend the single-layer method if
you will install mosaics or a combination
of tiles of different sizes, or if this is the
first time you install an electric radiant
heating system under ceramic tiles or
natural stones. The single layer method
is used most by experienced installers
in small applications with easy access
(example: a rectangular area in front of
the kitchen sink, but not necessarily a
small bathroom with an odd shape area
that is difficult to access).
Choose This
Waiting Period
Ceramic tile and stone installations require
2 to 14 days for the thinset to cure. You must
allow the thinset material to fully cure
before the WarmlyYours Floor Heating
System may be operated fully. Failure to
do so will result in damage to the system and
cause the thinset to become brittle.
Warmup Time
If you desire a warm up time of
approximately one hour, then the amount of
material above the heating element should
not exceed one inch.
FOR CARPET, VINYL OR
LAMINATED FLOORING
Two Stage Method
Embed the Heating Roll(s) in a first layer
of thinset or adhesive and let it dry.
Float a second layer of self-leveling
cement to obtain a smooth, flat surface.
A minimum total for both layers is 3/8”
of thinset, self leveling cement and/or
adhesive is recommended.

Electrician’s Guide
NAILED HARDWOOD FLOORING
On the plywood subfloor you need to place wood
sleepers every 18”. These spacers are 3/8” or
1/2” high and about 1” to 2” wide. They create 18”
lanes in which you would place the WarmlyYours
Heating Roll(s). Make sure your Installation Plan
has incorporated that feature or call WarmlyYours
at 1-800-875-5285. The Heating Roll(s) is then
covered with 3/8” of self leveling cement to
come up to the level of the wood sleepers, and
finally, the hardwood floor is nailed into the wood
sleepers

Call An Electrician!
A tile-setter, flooring contractor or
qualified Do-It-Yourselfer can install the
WarmlyYours Floor Heating System.
A qualified electrician must complete
the electrical connections of the
system to the main electrical circuit in
accordance with the National Electrical
Code or local codes.
If you would like help locating an
experienced electrical professional,
please contact WarmlyYours. We have
worked with hundreds of electricians
and will be happy to try and locate one
in your area.

IMPORTANT
Checking Continuity for
Electrical Short Circuits
Ohm Reading #3
Take a third Ohm reading to check the Heating
Element for damage.
Record readings on Page 9 of this guide. At this
time your three readings should match within the
15% variance.
On rare occasions during the installation
process, the insulation between the
tinned multi-stranded sheath and the
core conductor of the Heating Element
may be damaged.
An opening in the insulation layer
may create an electrical short, even
though the Ohm reading from the white
conductor to the yellow or red conductor
is normal and does not indicate any
circuit break
There should be no continuity (that
is, an ‘infinite’ resistance reading, not
14
‘zero’) between the white conductor
and the white sheath.
There should be no continuity between
the yellow/red conductor and the
yellow/red sheath.
There should be a low resistance
reading between the white sheath and
the yellow/red sheath.
Connect Electricity
Before shortening the cold leads, make
sure the color indicators on the wire
are visible at the box and thermostat
location. If not, place a piece of
corresponding colored tape on each of
the leads.
Floor Sensor
Connect the sensor wire to the
designated screws on the terminal
block on the base of the thermostat.
The sensor wire must pass outside the
electrical box and follow the wall down
to the floor.
As the sensor wire is low voltage, most
electrical regulations do not demand
conduit. However, do not house the low
voltage wire in the same conduit as the
120 or 240 volt return power lead wires.
Electrician’s Guide
- Trouble Shooting
The electrical wiring should follow
the wiring instruction schematic
provided. Multiple Heating Rolls may
be connected in parallel to the same
control device. The Heating Rolls
may not be connected in series to
each other.
Examine System
The amps rating of the control device
limits the total number of Heating Rolls
that can be controlled by a single control
device. A Relay Contactor or Power
Modules is required when the amps
drawn is greater than the amps rating
of the field installed control device.
1. Make sure the breaker or fuse is
delivering power to the system.
GFCI
The Floor Heating System must be
connected to the electrical service
via a Ground Fault Circuit Interrupter
(GFCI).The GFCI feature may be
incorporated in the thermostat. A GFCI
circuit breaker will be needed ONLY if
using an RC-40 Relay. GFCI protection
is not provided by the thermostat when
using an RC-40 relay.
The WarmlyYours Floor Heating System
is maintenance free and guaranteed
for 10 years against factory defects. If
a complete system fails to function as
expected, first check the following:
2. Re-read all control device
instructions.
3. See if the Ground Fault Circuit
Interrupter (GFCI) has been tripped.
This could indicate wire faults, but
may be due to external factors such
as a power surge.
If your system contains more than one
Heating Roll and you have a cold area, or
if the above actions do not yield results,
you will need to call your installer. Be
sure to give the Model Number from the
UL label(s) of your system.
Electrician’s Guide - Trouble Shooting (Cont.)
If further technical assistance is necessary, your electrician
may contact WarmlyYours.com at 1-800-875-5285.
Note: “Beware Of Using A
Continuity Checker!”
Our smaller Heating Rolls have a high Ohm resistance and
some continuity checkers do not send enough current to
go through and emit the noise or light that affirms proper
continuity. If your instrument cannot function on a small
Heating Roll, please use a digital Ohm meter.
Electrical Fault-Finding
Once the system has been turned off and made safe, have
a suitably qualified person:
1. Ensure all wires have been connected as per the
wiring diagrams.
2. Make sure multiple rolls have been wired in parallel
and not in series.
3. Confirm that control devices are receiving correct
voltage.
Use a well calibrated digital Ohm meter with good batteries.
The Ohm resistance level of each Heating Roll should be
checked and the reading compared with the resistance that
was recorded during installation on the corresponding UL
label(s) (located on the circuit breaker) and in the log on
Page 9 of this Manual.
If your reading is not within the 15%+/- range from the
original reading, the roll may be damaged in some way.
If you get zero across the core or ground sheath, this
indicates an open or short circuit beneath the finished
flooring. The electrical contractor must locate the point of
break or short, in coordination with the Technical Services
Department of WarmlyYours.com.
Locating A Break Or A Short
Checking For Electrical Short
If your installation is complete, all wiring connections have
been verified to be correct, including grounding of the
system, you have checked the sensor wire for proper Ohms
reading, and you suspect the system is still not working; you
need to determine if there is a break or a short under the
floor.
In some rare occasions an installation may have suffered
from a high pressure point that broke the insulation between
the core conductor and the tinned multi-stranded sheath.
Such an opening in the insulation layer can create an
electrical short, even though the Ohm reading from the
white conductor to the yellow or red conductor is normal and
does not indicate any circuit break. In these rare occasions
a continuity test will show continuity between the white core
conductor and the white sheath wires, and/or between the
yellow or red core conductor and the yellow or red sheath
wires.
Checking For Breaks
The Ohm resistance of each roll should be measured from
the core of the yellow or red conductor wire at one end, to
the core of the white conductor wire at the other end.
Make sure the probes of the Ohm meter do not touch the
sheath wire at either the yellow/red or the white ends.
Make sure you do not touch either of the probe ends with
your fingers, or the meter will be reading your internal body
resistance.
Make sure your Ohm meter is set on the proper scale (0-to200 for Heating Rolls, or 0-to-20,000 for the sensor wire).
Your Ohm resistance readings should come within 15%
(plus or minus) of the original measurement indicated by the
factory on the UL label.
If your Ohm reading is within 15% of what it should be, there
is no break. However, you still need to check for an electrical
short.
There should be no continuity (=“ infinite” resistance reading,
not zero) between the white conductor and the white sheath.
There should be no continuity (=“ infinite” resistance reading,
not zero) between the yellow/red conductor and the yellow
or red sheath.
There should be a low resistance reading between the white
ground sheath and the yellow/red ground sheath (generally
under 3 Ohms, never over 8 Ohms in 120V rolls or 14 Ohms
in 240V).
If your instrument reveals continuity between the white core
conductor and the white sheath, there is a short in the circuit.
You can approximate the location of the circuit short with
4-Ohms resistance measurements.
If your Ohm reading is lower (outside the 15% range), but
there is clearly some continuity, check your Ohm meter and
your batteries. If these are good, there is a possibility that
you have several electrical shorts.
Infinity Ohm Reading?
If you have absolutely no reading (= infinity on your meter),
and you are sure you adjusted the setting of the Ohm meter
to the correct reading range (0-to-200 for the Heating Rolls,
or 0-to-20,000 for the sensor wire), then you have a break (=
total cut) in the conductor.
15
Approximating The Location
Of An Electrical Short:
In order to locate the approximate position of the short,
you need to take 4-Ohm resistance measurements:
1. From the white core conductor to the yellow/red
core conductor.
Owner’s Information
Check The Work
Make sure the person doing the electrical work has:
2. From the white sheath to the yellow/red sheath.
1. Completed the log on Page 9 of this Manual.
3. From the white core conductor to the white
sheath.
2. Labeled the circuit that supplies the WarmlyYours Floor Heating System.
3. Remembered to put the UL label/s in a safe place (e.g. taped to the circuit breaker
door) for future reference.
4. From the yellow or red core conductor to the
yellow/red sheath.
The percentage ratio of the third and fourth Ohm
measurement reveals the approximate location
of the circuit short. For example: if the third Ohm
measurement is 25% of the total of third-&-fourth
Ohm measurement, the circuit short is approximately
at 25% of the roll length, starting from the white end.
There is another way to locate breaks or circuit shorts
with an underground fault detector.
A short can most easily be found with a “time domain
reflectometer” tester, which will measure the distance
of the wire between the tester and the short point.
WarmlyYours has several of these testers available
to assist our installers.
Breaks and shorts may generate some heat and they
can also be found with infra-red cameras scanned
over the floor.
Have your electrician call WarmlyYours.com at
1-800-875-5285 if you need any assistance.
16
Be sure to record the Electrician’s details on Page 8 of this Manual. It will be helpful
to use the installation Notes section below to record any information about your
installation for future reference.
Installation Plan
When the floor surface is laid over the embedded Heating Roll(s), ensure care is taken
not to drill or drive nails and screws in the vicinity of the Floor Heating System.
Make everyone aware of the Installation Plan.
The Installation Plan should be passed along with the sale of your home.
At no point in time should there be walls or permanent fixtures installed over the heated
areas of the system. It is your responsibility to pass this information along to the next
homeowner or any remodelers.
