Heatwave Mats & Cables

heatwave-logoHeatizon Systems Heatwave Radiant Floor Heating Mats and Cables are a convenient and economical way to add heat to smaller areas or chained together for larger areas. The mats layout to provide for an easy installation by simply rolling it out, while the cables can be used for more difficult shapes or heating around amenities.  Both of these systems are a directly hooked up to one of our GFCI programmable thermostats that is included in each kit. Larger systems can be designed by using our contactor or relay panels that switch more load than a single thermostat. Mats and Cables are available for 120V or 240V and are designed in a number of lengths to fit any particular application making them a perfect off the shelf floor heating solution. Both systems are perfect for DIYers, handymen, or contractors in a variety of environments.

The cable and connection points MUST be completely embedded so that you cannot see the red cable or connection points, there is no maximum depth of thinset/mortar.

Category: Heatwave

There are a few methods to secure the cable to the floor until it is embedded:

  1. Use a small amount of tape to hold the cable tot he floor. (do not cover ALL of the cable, just use small perpendicular strips to secure it)
  2. Hot glue is acceptable, provided that the tip of the glue gun DOES NOT touch the heating element. Do a small drop on the floor and press the heating cable into the drop.
  3. The mat comes with a tape on one side of the mat to aid in securing it to the floor.
  4. Staples may be used on the mesh portion of the mat. (DO NOT STAPLE THE RED HEATING CABLE)

Should you wish to bypass the various scheduling options on the M429 thermostat, follow the following procedures:

  1. Press the OK button twice to activate the main menu.
  2. Use the UP or DOWN buttons to scroll to MODE, then press OK.
  3. Use the UP or DOWN buttons to scroll to MAN. MODE, then press OK.
  4. Set desired temperature and press the OK button.
  5. Use the UP or DOWN buttons to scroll to EXIT, then press OK.
  6. Your thermostat will now maintain the set temperature. (Note: power bumps/losses may reset the thermostat back to a pre-programed schedule.)

NOTE: Using the thermostat in this manner may cause excessive power usage, especially if the space is inadequately insulated and/or the desired temperature is very high.

This is a sensor problem, here are a few fixes:

  1. Check to ensure the thermostat is firmly connected to the “C” and “D” ports behind the face plate of the thermostat.
  2. If you did not install a floor sensor or it is damaged, set the thermostat to red ambient temperature:
    1. Press the OK button twice to bring up the main menu.
    2. Use the UP or DOWN buttons to scroll to SETTINGS, then press OK.
    3. Use the UP or DOWN buttons to scroll to APPLICATION, then press OK.
    4. Use the UP or DOWN buttons to select ROOM, then press OK.
    5. Set desired temperature (some model of thermostat)
    6. Use the UP or DOWN buttons to scroll to EXIT, then press OK. (do this twice)
    7. Your thermostat will now measure the temperature of the room and NOT the floor sensor. (TIP: You may have to adjust the thermostat temperature higher or lower than expected to achieve desired floor temperature.)
  3. Test the floor sensor to measure resistance to check for resistance.
    1. Set your multimeter to the 200k Ohm (Ω) setting.
    2. touch a probe to each end of the sensor wire.
    3. A functioning floor sensor should get a reading between 9,000 and 25,000 ohms, if the sensor fails this test, please see #2 for how to switch to ambient air sensor.

NOTE: Whenever working on ANY wiring for the thermostat, please TURN OFF the breaker powering the thermostat and floor heating system.

The black connections points at the end of the heating cable and between the red heating cable and the black cold lead are engineered connection points and WILL heat up and it is crucial that BOTH of these connection points get fully embedded in thinset and/or mortar.

Since these connection points are thicker than the heating element, best advice is to chisel out a small groove for the connection point to sit in, in order to lower it’s profile.

The floor sensor is located inside the box containing the thermostat. It is a separate thin-gauge cable from the heating mat/cable.

Category: Heatwave

The black cable that attaches to the red heating cable is called the COLD LEAD (as it does NOT heat up). It is designed to be able to be cut and or shortened in order to better accommodate reaching the Thermostat location.

Category: Heatwave

There are a few things to do to mitigate excess cable/mat:

1. The best advice is if you still can return the mat/cable to Amazon especially if you have a large amount of excess cable and get the next size system down.
2. Tighten spacing between cable spacing (keep at least 2 inches of space between heating cable) and DO NOT overlap ANY heating cables or heating cable over any other cable.
3. Remove cable from the mat and run it into areas where the mat does not fit. (Use a small amount of tape or glue to keep the heating cable in place.)

Reminder, DO NOT, UNDER ANY CIRCUMSTANCES, CUT (OR ATTEMPT TO SHORTEN) THE READ HEATING CABLE. The heating cable is specifically engineered to be the length it is.
