QL5AC2012TX13TEMPERATURE TRANSMITTER

1 REMOTE UNIT Inserting batteries The remote unit uses two “AA” batteries. To install or replace the batteries, please follow these steps: 1. Remove kickstand base. 2. Unscrew the screw on the back of the compartment and remove the cover. 3. Insert the batteries observing the correct polarity. 4. Replace the battery cover on the unit and seal by re-screwing tightly. 5. When a “Low Battery” symbol appears on the part of Outdoor Temperature, please replace batteries of the remote unit. 6. At few occasions (interfered by environment, for instance), the LCD display might be abnormal, and then reload the corresponding batteries until it is ok. 7. After installation of the new batteries, the setup procedures need to be performed. (See Setting the remote transmitter(s) Setting the remote transmitter Upon power up the temperature RF signal is sent from the transmitter to the main unit automatically. Please place the transmitter outside in a dry, shaded area. Try relocating the transmitter if the main unit does not display the outdoor temperature after 3 minutes. There are 2 buttons inside the back of remote. 1) O C/ O F--- To change the remote displays Centigrade or Fahrenheit 2) TX --- To test communication between remote and main unit 2 SAFETY INSTRUCTIONS Do not expose the appliance to strong temperature variations, humidity, direct sunlight or dust. Keep the remote out of reach of small children. Attention! Batteries can be life threatening, if swallowed. Therefore, keep batteries and clock out of reach of small children. If a battery has been swallowed, seek medical advice immediately. The batteries provided must not be charged or re-activated by any other means, taken apart, thrown into fire or short-circuited. Batteries need to be properly disposed of. For this purpose, shops selling batteries provide special containers for environmentally friendly disposal.

CIRCUIT DESCRIPTION TRANSMITTER SECTION (TX13) Frequency Determining and Stabilizing Circuit MCU (U1) output a data signal to RF, the Primary resonant network consists of Q1, R4, C10, C6, L3, L1and Y1. Thereunto, Y1 is a SAW resonator (Surface-Acoustic-Wave), to stabilize surging frequency 433.92MHZ; Q1, R4, C10, C 6,L3 and L1 supply surging condition. RF Amplification: The power of the primary output is low, the second level amplify RF signal and output. The RF amplification network consists of C12, R6, C7, C13, L2, C14, C15 and ANT. The C13 is a coupling capacitance. Thereunto, ANT is a transmitter antenna. Modulation: The MCU export data signal, the circuit adopt OOK modulating mode.
