Date. Prepared by History X1 July.1-2010 Mike Lin Initial release Circuit Description Page 2 of 3 There are three key units in the product:the control unit,the RF module and the LCD display module. 1. Control unit The key part of the control unit is the MCU (U1). It is a 16-Bit built in 256KB flash microcontroller. Its responsibility is to control the whole product: a. Communicate with the RF module (U3). Exchange data (receive and transmit) via RF module. b. Send display information to LCD module. c. Receive the key press information from the key in the front panel. d. Indicate the status of the product via the LED. e. Communicate with the EEPROM and flash. f. Control the relay to drive the contactor of the HVAC. g. Read the ambient temperature. h. Communicate with the RTC. 2. RF module The RF module is a complete ZigBee-ready module with integrated antenna. Its responsibility is to exchange data (receive and transmit) via the 2.4 GHz ISM band RF net. For more details,read the reference specification of the RF module please. 3. LCD display module The LCD display module(J1) is a FSTN LCD. Its responsibility is to display the information from the MCU. 4. RTC U11 is a high stability crystal built-in real time clock module. It provides the real time to the MCU via I 2 C bus for the time display and calendar. 5. Relays There are six relays which are controlled by MCU. And these relays connect the 24VAC power to drive the contactor of the HVAC via terminal (J3). 6. L detect The pin mark symbol ”L” in the terminal (J3) is a system error input port for the MCU to get the information of the HVAC system. 7. Power detect Circuit Description Page 3 of 3 D2, Q6, R43, R38, C20, R30, C18 and R39 form the 24VAC power detection circuit for the MCU to get the information of the power supply status in AC24V system. 8. Thermal Sensor RT1 is a thermistor for MCU to get the ambient temperature information. 9. System switch SW1 is a switch for the user to select a HVAC system. 10. EEPROM/Flash U2 and U10 are memories for storage the program code, the status configured by user and other important information. 11. Program port The J2 is a combination program port for program the MCU and the RF module. 12. Power supply Pin RC and C of J3 is the power input (24VAC). D8 and associated circuit is the rectifier. Q8 and associated circuit is the voltage clip unit. U6 and associated is the DC-DC voltage regulation circuit. It outputs a +4.7VDC. U9 and associated circuit is the LDO voltage regulation circuit. It outputs a +3VDC to MCU, LCD, RF Module etc. - End - CT-EM2606 CIRCUIT DESCRIPTION 1. Power Supply: We can power on the unit though VBRD, because there is a 1.8V regulator in the chip (EM260) and regulate the input power supply to stable 1.8V, so the power supply can range from 2.7 to 3.6V DC. 2. EM260: The EM260 integrates a 2.4GHz IEEE 802.15.4-compliant transceiver with a 16-bit net processor(XAP2b core) to run EmberZnet. The transceiver utilizes an efficient architecture that exceeds the dynamic range requirements imposed by the IEEE 802.15.4-2003 standard by over 15dB. The integrated regulator, VCO, loop filter, and power amplifier keep the external component count low. 3. SKY65337: SKY65337 is high-efficiency Front-End Module for ZigBee and other 2.4GHz ISM band applications. It contains a 2400-2500MHz high-efficiency transmit path and a low-lose bidirectional path. The transmit path consists of an harmonic filter, an balun and an PA capable of providing +20dbm of power at the antenna port. The bidirectional path consists of a high isolation T/R switch and an balun for low-noise differential port. 4. TX/RX control: It is builded of Q1,Q2,R3,R4,R15,R16,R17. The signal of TX is low, U2 set up bidirectional path, U2 can be transmit and receive. The signal of TX is high, U2 set up transmit path. 5. Antenna: A PCB’s antenna is used to transmit and receive 2.4GHZ carrier signal ,The component of C2,C3,L3 are matched circuit for antenna.

INTERTEK TESTING SERVICE Report No.: HK10060857-1 FCC ID: DI2GES2181 RF Exposure Evaluation For Maximum Permissible Exposure (MPE) evaluation of the device, the maximum power density at 20 cm from this mobile transmitter shall be less than the General Population / Uncontrolled MPE limit in OET Bulletin 65. For the device of tested model of GES2181, the maximum conducted measured power (P) was 64.12mW. From these data, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: The maximum peak conducted power = 64.12mW The power density at 20 cm from the antenna = P / 4πR 2 = 0.013 mWcm -2 The measured maximum field strength (FS) was 117.0 dBμV/m. The distance (D) between the antenna and the equipment under test (EUT) was 3 meters. From these data, the radiated (EIRP) can be calculated by: The radiated power = (FS*D) 2 / 30 mW = 150.4 mW The power density at 20 cm from the antenna = P / 4πR 2 = 0.03 mWcm -2 In the frequency range of 2.4-2.4835 GHz, the MPE limit is 1.0 mWcm -2 for general population and uncontrolled exposure. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be ensured by indicating the minimum 20cm separation between the transmitter's radiating structures and body of the user or nearby persons. The following RF exposure statement is included in the user manual: “FCC RF Radiation Exposure Statement: This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body.”
