                        !    "  # $      " %& Mounting thermostats: 1. If necessary, release the housing cover by screwing the housing cover set screw in (CW). 2. Remove the housing cover by lifting from the bot- tom until the housing cover clears the top tabs. 3. Remove the battery, if present, to access the mount- ing hole. 4. Mount the thermostat with the screws provided. 5. Re-install battery, observing correct polarity. 6. Press the Reset button. NOTE: Doublestick tape may be used to mount thermo- stats. Installers should evaluate potential damage to wall surfaces before using tape. Replacing the housing cover: 1. Place top of housing on housing cover top tabs. 2. Close the cover. 3. Turn the housing cover set screw out (CCW) to secure the cover. Programming Transmitters: •In many applications, it is not necessary to program FA7236 series thermostats. Factory default pro- gramming gives each transmitter a unique identifi- cation number which can be decoded in the user’s software to identify the source of temperature data. •Some software developers may wish to assign ID numbers to transmitters, and to set other parame- ters. This data can be loaded into the transmitter via the programming header. Contact Inovonics techni- cal Service for details. NOTE: FA7236 series thermostats retain programming data in non-vola- tile memory. They do not require reprogramming after loss of power. Any time the battery is replaced in the transmitter, the Reset button should be pressed to re-initialize the transmitter and to restore the most recent programming.

This product is a wireless thermostat typically installed in a commercial building. Units are located anywhere you would install a thermostat for controlling building temperature. The unit measures the ambient temperature and sends this information to a receiver attached to the building’s HVAC system. Let me know if you require any additional information.

CONFIDENTIAL FCC ID: HCQ3B6THT, FA7236SO 3/4/2003 Measurements performed at Inovonics Wireless Corp. lab Equipment used: HP 8594E Spectrum Analyzer—calibration due 5/6/2003 The antenna was removed from the EUT and a direct connection made to the transmitter output. 1. Plot 1 is a spectrum plot showing the carrier frequency separation. Compliance with section 15.247(a)(1) is demonstrated with a test sample configured with firmware allowing two adjacent channels to be captured. 2. Plot 2 demonstrates compliance with 15.247(a)(1)(i) — Number of hopping channels. This is a stored display of many sequential transmissions to show the overall band occupied by the transmitter. 3. Plot 3 shows the 20 dB bandwidth of a single channel to demonstrate compliance with 15.247(a)(1)(i). 4. The duty cycle is calculated over a 100 mSec averaging window as specified in the rules. The longest message contains a total of 213 pulses each 20 uSec in duration, for a total transmitter on time of 4.26 mSec with represents a worst-case duty cycle of 4.26%. The duty cycle correction used is the maximum of 10%. 5. Calculation for compliance with MPE requirements (Section 2.1091) using a worst case of 0.02 Watt, unity antenna gain, and the f/300 (mW/cm 2 ) limit for general applications. This device is used in fixed locations and is not carried or worn by the end user. The key factor is duty cycle. Under normal conditions, a 12-packet message is sent a maximum of once every 15 minutes. Worst case, a 12-packet message is sent once per minute or 72 packets in a 6 minute period. Total On time per packet = 4.26 mSec (for maximum packet length) Duty Cycle = (4.26 x 72) mSec/(6x60x1000) mSec = 0.0852% EIRP = (0.02W)(0.000852) = 17.04 microwatt. Using a distance of 20 cm: 17.04 microwatt / (4 pi 20 2 ) = 3.39 nW/cm 2 6. The Dwell Time is the length of one packet. The worst case dwell time for an extended length packet is 40.1 mSec. The standard packet is about 30 mSec duration. A worst case transmission rate, corresponding to a repeated change of state transmissions would result in a maximum of 12 packets in any 10 second period with each packet on a different frequency. The maximum dwell time is thus the dwell time of an extended packet or 40.1 ms.
