Troubleshooting Tips for Control Units

admin Leave a Reply

control unitOne of the many benefits of electric radiant heat is its solid-state design. In contrast to the pumps, boiler, and liquid-filled tubes of hydronic systems, electric systems involve no moving parts. Our cable and mesh systems operate for years when installed properly, all with no regular maintenance.

However, as with all things mechanical or electric, unexpected problems may arise. Whether due to accidental damage or gremlins it is important to be able to troubleshoot any issue that may arise.

If your system doesn’t appear to be working, first ensure there is power to your control unit. Make sure the breaker switch on the control unit and distribution panel are in their proper position.

These lights blink to indicate various faults. The lights and their meaning are listed in the installation manual. Our CBX 7 units have a single light indicating whether the system is in fault. We recommend calling for technical support to resolve these lights.

Finally, you can check the heating element for continuity if you have access to a meter or continuity tester. This will ensure there is no damage or shorts along the heating element.

As always if you do have an issue with your system our team is available to provide technical support and troubleshooting over the phone. Our distributors are also an excellent resource and may be able to provide help in person.

Heating Linoleum Floors

heated linoleumLinoleum has long been a popular flooring choice for its cost and durability. Linoleum and variants like Marmoleum have seen a resurgence lately due to their natural composition and environmentally friendly qualities.

Radiant heat pairs with linoleum products for added comfort. Heatizon offers a number of products suitable for heating linoleum, but our ZMesh does it best.


A bronze mesh that is rolled out beneath a variety of floor coverings, low voltage ZMesh provides a comfortable, even heat. This unique product from Heatizon is a great solution for heating under linoleum and similar floors, as well as wood, carpet and floating floor systems.

Glue Down Sheets or Tiles

Linoleum is commonly installed as sheets that are glued down. For heating these sheets, ZMesh is laid out and either stapled to the wood subfloor or glued down to a concrete subfloor with a tile mastic. Care is taken to keep the mesh flat for minimum floor buildup.

A thin sheet of plywood or lauan is placed over the mesh, and the linoleum is glued down. This same process works for glue down linoleum tiles.

Floating or Click Systems

Linoleum is also becoming more common in click install or floating systems. ZMesh is perfect for floating floors as it is installed over the subfloor and covered with an underlayment. The floating floor system can then be installed directly over the mesh and underlayment.
