Setup and Installation
Proper installation is crucial for the safe and efficient operation of your heating system. Always consult local electrical codes and regulations before beginning installation. It is recommended that a qualified electrician perform the electrical connections.
Components Overview:
- TapeMat: The open-weave mat containing the heating cable. The orange mesh can be cut to fit the layout, and the blue heating wire can be carefully pulled out and routed around obstructions. Do not cut the blue heating wire.
- SunStat Command Thermostat: The control unit for your heating system.
- LoudMouth Installation Monitor: Used to continuously monitor the heating cable during installation for potential damage.
- Double-Sided Tape: For securing the mat to the subfloor.
Installation Steps:
- Plan Your Layout: Determine the area to be heated and create a detailed layout plan. Ensure the mat and heating cable avoid permanent fixtures like cabinets, toilets, and bathtubs.
- Prepare the Subfloor: Ensure the subfloor is clean, dry, and level. Apply double-sided tape to the subfloor according to the layout plan.
- Lay the TapeMat: Roll out the TapeMat onto the prepared subfloor. The open mesh allows for easy cutting and flipping to accommodate turns and irregular shapes. Carefully route the blue heating wire around obstacles as needed, ensuring it is not cut.
- Connect LoudMouth Monitor: Connect the LoudMouth monitor to the heating cable leads. Turn it on to continuously monitor the cable for damage during the subsequent steps. An audible alarm will sound if the cable is compromised.
- Apply Thin-Set or Self-Leveling Mortar: Once the mat is securely in place and monitored, apply a layer of thin-set mortar or self-leveling compound over the mat, embedding the heating cable.
- Install Flooring: After the mortar has cured, install your chosen flooring (tile, stone, or laminate) according to the manufacturer's instructions.
- Thermostat Installation: Install the SunStat Command thermostat in a suitable location, typically on an interior wall. Connect the heating cable leads and floor sensor to the thermostat as per the thermostat's specific wiring diagram.

Maintenance
The SunTouch TapeMat Electric Floor Heating Kit is designed for minimal maintenance once installed. The heating cables are sealed and do not require regular servicing.
General Care:
- Keep the thermostat clean by wiping it with a soft, damp cloth. Avoid abrasive cleaners.
- Ensure the floor sensor is not obstructed or damaged during any floor modifications.
- Regularly test the Ground Fault Circuit Interrupter (GFCI) on the thermostat as recommended in the thermostat manual (typically monthly).
Troubleshooting
If you experience issues with your SunTouch floor heating system, refer to the troubleshooting section in your SunStat Command thermostat manual for specific guidance. Below are some general troubleshooting tips:
Common Issues:
- No Heat: Check if the thermostat is powered on and set to a temperature above the current floor temperature. Verify the GFCI has not tripped.
- Uneven Heating: Ensure the heating mat was installed correctly and the cables are evenly spaced. Cold spots might indicate improper installation or damage to a section of the cable (unlikely if LoudMouth was used).
- Thermostat Error Codes: Consult the SunStat Command thermostat manual for explanations of any error codes displayed on the screen.
