What is the acceptable deflection for a floor that will be tiled?


“Traditionally, the accepted minimum requirement for floor rigidity is L/360 – before the tile underlayment is installed. The L/360 standard means that the floor should not deflect more than the “span” divided by 360. If the span of the joists is 10 feet (between supports), then the deflection should not be more than 1/3″ between […]

SOLVED: Error Code 120: kWh rate entered in the wrong format.

Why is my Floor not Reaching Target Temperature?


If your heating system was installed on a concrete slab or over an unheated space and insulation boards were not used, it is possible that the heat loss into the subfloor will cause your floors to heat up more slowly and possibly not reach the target temperature. Click “Read More” for details.

Why does my thermostat trip every time it reaches the same temperature?


The resistance for your mat or cable is calculated on the length of the heater. Shortening the heater would increase the resistance and thereby the temperature. The cable is expected to operate fine at slightly higher temperatures for a time, but it may put undue strain on the end-splice, which may then trip and eventually fail.

Why does my thermostat read a percentage?


When applied, you will select a number and this percentage represents the number of minutes the heat will be on out of every 10 minute cycle. For example, if you select 60%, the heat will be on for 6 minutes, followed by 4 minutes of the system being off. Then, after the 4 minutes, it will activate again for 6 and so on. This will continue until your programmed heating period ends or until you manually turn off the heat.
