BASIC TRANSMITTER FUNCTIONS & MODES
IMPORTANT:
The transmitter requires two AAA-size 1.5V batteries (excluded). New (fully charged) batteries are required for proper
functionality of the system. Insert batteries into the transmitter battery compartment on the back, positioning the (+) and (-)
ends of the batteries as indicated on the casing. (Fig. 1) When the batteries are inserted properly, LCD will display initial
numbers.
Due to the temperature-monitoring components in the transmitter, it is important to allow the transmitter to detect the room
temperature before accurately displaying room temperatures on the screen. Normally it takes 5 to 15 minutes for every first
time placing this transmitter in a new location / environment.
To begin the mode cycle (Fig. 3), press and release the MODE button (Fig. 1) until the LCD screen reads OFF (Fig. 4).
Step 1: Press the MODE button to manually turn ON the receiver (Fig. 5). Timer is available in this mode.
The receiver will make sounds of quick BEEP X 2 (♫, ).
Step 2: Press the MODE button again to enter the THERMO mode (Fig. 6).
Timer and Thermostat are both available in this mode.
NOTE: The Thermostat has the priority to turn OFF when the room temperature reach desired set temperature, and it will
turn ON again when the room temperature go below desired set temperature, at the meantime, Timer will keep countdown.
However, once the set time ends, the Timer will turn OFF the entire system and go back to OFF mode (Fig. 4).
Step 3 : Press the MODE button a third time to turn the appliance back OFF again as show in (Fig. 4).
The receiver will
make sound of continuous BEEP for one second (♫~~~~).
