Where do I place the sensor probe when installing the DCM-PRO cables?
The sensor probe for the Warmup thermostat should be in the center of two element heating runs at least 12” into the heated area.
Ensure that the sensor probe does not touch or cross any of the heating cables. Feel free to cut or chisel a channel into the insulation or sub-floor to avoid the sensor probe from raising the floor height. Warmup recommends installing a second “backup” probe for every thermostat.
- Length: 10ft or 3m
- Cable thickness: 1/8″ or 3mm
- Probe dimensions: L * W = 5/8″ x 1/4″ or 20mm x 6mm
- Cable gauge: 24Ga 2-signal low voltage wire (extendable to 90ft)
Additionally, feel free to secure the sensor probe to the sub-floor by placing strips of tape over the low voltage communication wire to hold the probe in place. Do not cover the actual probe with the tape. This may result in a damaged probe or inaccurate probe readings.
Lastly, make sure to check the resistance readings of your probe before, during and after installation. Your multimeter should be set on a 20k ohm scale and get resistance readings between 7 and 17 ohms. Anything outside of this range should prompt you to call the Warmup Technical Department. Consult the installation manuals for further details.
