Without a thermal break, the concrete acts as a heat sink. Therefore, the heat is drawn first into the concrete sub-floor before your floor covering. This is why Warmup recommends installing Warmup Insulation Boards over the concrete sub-floor to act as a thermal break. This forces the heat radiate upwards first rather than down into the concrete slab. Warmup insulation boards can increase ramp up time by over 70% and decrease heat loss by over 90%.

Instead, try pulling the cable off the mesh and spacing the cable every 2 or 2.5 inches apart. Consult your installation manual with further questions regarding where the cable or mat can be run.
The COMMBOX-600 is a “Plug and Play” controlled power distribution panel for frost protection, ice and snow melting projects. When receiving a signal from the sensor(s)m the contactors are activated, energizing your heating system. DIP switch settings determine how the zones activate. When programming your system, make sure DIP switch 1 is in the ON position. The program manual can be navigated by using the SELECT (+) to move forward or SELECT (-) to go back through settings.
The thermostats come with a 9’ sensor cable to detect the temperature under the floor finish. The end of the probe wire contains a capped sensor that should be evenly centered between two heating cables at least 12” into the heated area. At no time should the probe wire cross the heating cable.
The ground wire of the heater(s) must be directly connected to the ground wire of the supply.
12 AWG or 18 AWG should be used depending on the distance from the controller. Click “Read More” for details.
The amperage capacity of the Resibox is 120A and for the Commbox it is 230 Amps. The Resibox has (4) of the 30A/2-pole contactors rated 120-277V for a total of maximum 120A load capacity. Click “Read More” for details.
The 120V coil of the WSM-63 is powered between the one leg of 240VAc and a neutral they. Do NOT run both hots to the WSM-63. Please refer to the installation manuals for further information.
