Installation and Operation Instructions for the Wireless Temp/Humidity.

Point Six, Inc.

Wireless Temperature/Relative-Humidity Sensor

Model Point Sensor Temp/Humidity

Installation and Operation Instructions

The Point Sensor Temp/Humidity sensor transmits a digital temperature, relative-

humidity (or light level) and a unique serial number to a 418 MHz receiver. The Point

Sensor Temp/Humidity is enclosed in a high impact ABS enclosure for direct surface

mounting in the environment to be measured. The Point Sensor Temp/Humidity is battery

operated.

Application: Apply the sensor to the surface to be monitored with double-sided

adhesive tape. Make sure that the side labeled with FCC ID is visible and away from any

metal surfaces.

Service Function: The wireless sensor has an installation mode switch. A momentary

push of this switch will start the convert/transmit cycles. When new and until this button

is pushed the Point Sensor Temp/Humidity will not transmit. The Point Sensor

Temp/Humidity will transmit a special installation status mark in the data packet

immediately after the installation/start switch is pushed. After the start a push of the

installation switch will result in the immediate transmission of temperature, relative-

humidity ID and installation status mark.

Battery: A 3.6 Volt lithium battery powers the Point Sensor Temp/Humidity wireless

sensor. The battery will last for more than 10 years in the idle state (as shipped from the

manufacturer). The Point Sensor Temp/Humidity will transmit data for as long as 5 years

at a rate of once each minute once started. The Point Sensor Temp/Humidity is

completely covered with a water resistant conformal coating to protect the electronics

from the environment and condensation. The user can replace the battery. The Point

Sensor Temp/Humidity may be placed in a quiescent state (battery life greater than 10

years) by holding the installation switch closed for more than 4 seconds.
