Examples of Common R-values for Floor Covering Materials* Floor Covering Material Thickness (inches) R-value Carpet 3/8 1.0 Tile (ceramic, mosaic) 1/4 0.15 Laminate 3/8 0.675 Plywood ½ 0.63 Natural stone (granite, limestone, marble, sandstone) 1 0.38 to 0.114 Wood 3/4 0.
SECTION 3 Planning the Installation 3.4 Calculation of On-Center Spacing (OC) In order to fit the TempZone™ Floor Heating Cable properly in the designated space, it is necessary to determine the spacing between the cables. This is called on-center spacing or OC. Refer to either the “Product Selection Guide--120V” or “Product Selection Guide--240V” in section 9 to determine appropriate spacing for the installation. Combine cable lengths if more than one is needed for the installation.
SECTION 4 Electrical Considerations 4.1 Floor Sensors and Temperature Control Floor Sensor (not required for all systems) Systems using a Smartstat™ Programmable Thermostat or Easystat™ Thermostat may require a low-voltage floor sensor. Carpet or laminate flooring manufacturers may require the use of a low-voltage sensor with their floor covering. Check with the manufacturer for specific recommendations. This sensor is embedded in the floor and monitors the floor temperature.
Electrical Considerations SECTION 4 4.2 Electrical Requirements for the System Where required, all electrical work for the floor heating cable installation must be done by a qualified, licensed electrician in accordance with local building and electrical codes and the National Electrical Code (NEC), especially Article 424, Part IX of the NEC, ANSI/NFPA 70 and Section 62 of the Canadian Electrical Code (CEC), Part I, as well as any other applicable statutory requirements.
SECTION 4 Electrical Considerations 4.3 Wiring Diagram COLD LEAD N ote: All electrical work must be done by a qualified, licensed electrician in accordance with local building and WIRE electrical codes, and the National Electrical Code (NEC), especially Article 424, Part IX of the NEC, ANSI/NFPABLACK 70 and Section 62 of the Canadian Electrical Code (CEC), Part I, as well as any other applicable statutory requirements.
SECTION 5 Installation and Operation 5.
SECTION 5 Installation and Operation Ground Wire 5.2 Pre-Installation Preparation Core to Sheath 5.2.1 Document the plan. Follow a SmartPlan™ obtained from WarmlyYours or prepare a floor plan of the area to be heated. Using a floor plan, with the TempZone™ Floor Heating Cable layout marked, makes it easy to Black trace the heating cable routing for troubleshooting if necessary. 5.2.2 Select the appropriate TempZone™ Floor Heating Cable, ensuring it is the correct lengthYellow and voltage.
SECTION 5 Installation and Operation 5.3 Circuit Check™ Instructions 5.3.1 Install TempZone™ Floor Heating Cable Install the floor heating cable in accordance with the design layout and instructions provided by WarmlyYours. 5.3.2 Test the Circuit Check™ Before connecting any wires, install the batteries in the device and turn it on and off to test the alarm.
SECTION 5 Installation and Operation 5.4 Installation of TempZone™ Floor Heating Cable 5.4.1 Install TempZone™ Cable Fixing Strips Install Cable Fixing Strips in a direction perpendicular to the direction the cable will run. Cable Fixing Strips should be installed at least 3 inches from the wall perimeter. WarmlyYours recommends securing the cable to the floor every 20 inches using tape or hot glue to keep the cable in position until the self-leveling underlayment is applied.
Installation and Operation SECTION 5 5.4.2 Install the TempZone™ Floor Heating Cable 1. Begin installing the heating cable from the thermostat or junction box. Follow the pattern marked on the floor plan (if supplied). Please note the thickness of the factory splice and cold lead and plan accordingly. 2. Unwind the cable from the spool. Secure it using the TempZone™ Cable Fixing Strips. Avoid bunching the cable or crossing over other parts of the cable. 3.
Installation and Operation SECTION 5 8. Apply thinset or self-leveling compound over the heating cable and subfloor. Acrylic, latex, or polymer-modified thinset cement may be used. Ensure that the material you select is compatible with the flooring material. Contact the adhesive manufacturer for more information and curing times. Ensure that there are no air gaps during application of thinset or self-leveling underlayment (SLU).
Installation and Operation SECTION 5 1. Weave the cable back and forth across the area at the desired spacing. Maintain slight tension on the cable to ensure it does not pull loose. If desired, use hot glue at intervals to help ensure it stays secure. NEVER space the cables less than 3” apart. RPM Mats 3” Spacing 3.5” Spacing 2. Mark where the factory splice will be placed. Cut the matting or membrane and insert splice.
Installation and Operation SECTION 5 5.4.4 Instructions for Installation Under Tile and Stone Flooring Option 1: Single-layer method for tile and stone Apply a layer of 3/8 inch latex-modified thinset cement or self-leveling underlayment (SLU) over the heating cable. Lay the tile or stone directly into that layer of thinset cement.
Installation and Operation SECTION 5 5.4.6 Instructions for Installation Under Hardwood Flooring Note : Although TempZone™ Floor Heating Cable is approved for direct contact with combustible material, WarmlyYours strongly recommends that the cable be embedded in thinset, self-leveling underlayment, cementbased adhesive glue, or tile adhesive under wood flooring surfaces.
SECTION 6 Testing 6.1 Testing the Cable IMPORTANT: Do NOT supply the system with electric current to test. All testing should be done with a digital ohmmeter. Supplying the system with a 120V or 240V electric current before the installation is complete is not needed to test the system. 6.
SECTION 6 Testing 6.4 Go by the Numbers The 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 black lead wire at the other end. Make sure that the probe of the ohmmeter does not touch the tinned sheath wire at either end. Do not hold the wires onto the probes with your fingers. Even your body’s electrical resistance can affect the reading if you touch the meter poles. A digital meter is easier to use and strongly recommended.
Operating Tips SECTION 7 7.1 Operating Tips 7.1.1 When first energized, the TempZone™ Floor Heating Cables may take approximately 1 to 3 hours or more to fully warm your floor. Heating results will vary depending on climate and building materials. 7.1.2 Energy consumption will vary depending on user preferences. To reduce energy consumption, set the thermostat to a lower temperature setting or operate for a shorter duration. 7.1.
SECTION 8 Troubleshooting 8.1 Identify the Problem If the system is not functioning properly, refer to the “Quick Reference Troubleshooting Guide” to determine the cause of the problem.
Troubleshooting SECTION 8 8.2 Troubleshooting 8.2.1 Locating a Fault in the TempZone™ Floor Heating Cable Use a Circuit Check™ device during cable installation. These devices will provide an audible alarm if the wire is damaged or cut during installation. A continuity checker is not acceptable for these tests.
Troubleshooting SECTION 8 8.2.2 Electrical Fault Finding If the system is not functioning properly, turn off the system and have a licensed, certified electrician perform the following: • Complete all steps of the installation process. • Verify that all wiring connections, including grounding of the system, are correct. • Check the sensor wire for proper ohm reading. • Ensure all wires have been connected, including grounding of the system, in accordance with the wiring diagrams.
Troubleshooting SECTION 8 Additional Information for Identifying Electrical Shorts In some rare occasions during installation, a high pressure point on the cable can occur and cause a break in the insulation between the core conductor and the metal sheath. This opening in the insulation layer can create an electrical short, even though the ohm reading from one line conductor to the other line conductor is normal and does not indicate a circuit break.
