Although one floor sensor is included with your floor heating thermostat, a backup floor sensor is recommended to be installed since sensors are difficult to replace once under the floor. If installing a backup sensor, only connect one at a time. Floor sensors rarely fail but they may be compromised by power surges or accidental damage to the floor. A back up floor sensor is low cost insurance providing peace-of-mind.
