5. Control device
The OWC-R heating cable system must be controlled with an adequate temperature regulator depending on the
type of system selected: floor control mode or ambient control with floor limit mode.
5.1 Installation for floor control mode
We recommend using an electronic floor temperature control device with a temperature sensor so the thermal
gain never exceeds the maximum temperature allowed for the type of floor covering selected.
Control device
recommended: Electromechanical thermostat with floor mode (F) and temperature sensor.
5.2 Installation for ambient control with floor limit mode
The thermal control device is an ambient thermostat. Because the thermostat reacts to ambient temperatures
and not floor temperature, the floor covering must be selected according to a higher tolerance level. The
ambient thermostat or temperature sensor should never be installed where sun rays are prevalent or in an area
subject to drafts.
Control device recommended: Electromechanical thermostat with ambient mode (AF)
and temperature sensor.
NOTE : Ouellet Canada Inc. highly recommends connecting the concrete cable system to a ground fault circuit-
breaker/detector (GFCI), built-into the control device or directly integrated into the circuit-breaker.
