KMC Room Sensors and Thermostats

KMC Controls manufactures a variety of pneumatic, analog electronic, and

digital room sensors and thermostats. Some sense only temperature, while

others also add humidity, motion, and/or CO

sensing. This document covers

general principles for mounting and maintenance of room (temperature,

humidity, motion, and CO

) sensors.

KMC also sells other kinds of sensors (e.g., duct, air flow, smoke, carbon

monoxide, pressure) that are not covered by this document.

For additional general information about sensors, see the following information

Handling Precautions For digital and electronic sensors, thermostats, and controllers, take reasonable precautions to prevent electrostatic discharges to the devices when installing, servicing, or operating them. Discharge accumulated static electricity by touching one’s hand to a securely grounded object before working with each device. Mounting for Optimal Temperature Sensing For effective temperature sensing, mount the thermostat or sensor in a location enabling it to sense the general room environment.
PAGE 3
Mounting for Optimal Motion Sensing For motion sensing models, mount the sensor on a wall that will have an unobstructed view of the typical traffic in the coverage area. Some of the issues that affect temperature sensors also affect motion sensors. See Mounting for Optimal Temperature Sensing on page 2. When choosing a location, the motion sensor must NOT be: • Behind curtains or other obstructions. • In locations exposed to direct sunlight or heat sources. • Near a heating or cooling inlet or outlet.

Mounting Height Traditionally, thermostats and room temperature sensors have been mounted approximately 60 inches (152 cm) from the floor. This has been considered an effective height to measure the room temperature and to allow a person to adjust a setpoint while standing. However, for thermostats (and sensors with adjustable setpoint controls), the Americans with Disabilities Act (ADA) has rules to ensure that public lodging spaces and facilities remain accessible to the disabled.
PAGE 6
Troubleshooting (Location) To correct or compensate for sensing problems caused by mounting issues: • Reposition the sensor or the surrounding obstructions. See Mounting for Optimal Temperature Sensing on page 2 and Mounting for Optimal Motion Sensing on page 3. • Insulate the sensor from air leakage and heating/cooling sources. See Reducing Temperature Sensing Errors on page 6 and Mounting Components and Height on page 5. • Adjust the sensor calibration to offset the environmental issues.
PAGE 7
Maintenance To maintain accurate temperature and humidity sensing, remove dust as necessary from the ventilation holes in the top and bottom of the case. To clean the case or display, use a soft, damp cloth (and mild soap if necessary). Clean Case Holes and Surface To maintain maximum sensitivity of the built-in motion sensor, occasionally wipe dust or dirt off the lens—but do not use any fluid on the sensor.
