This Durablow remote control system have a OUT-OF-RANGE SAFETY ALERT function which alerts when the
transmitter is out of the normal 20-foot operating range of the receiver for all operation modes. The transmitter sends an
RF signal every fifteen minutes to the receiver box to indicate that the transmitter is within the normal operating range of
20-foot.
If the receiver does NOT receive a signal every 15 minutes from transmitter, the receiver will begin a 120-minute
countdown. If during this period, the receiver does NOT receive a signal from the transmitter, the receiver will shut down
the system (OFF). Then the receiver will beeps rapidly for 10 seconds, and after that, the receiver will continue to beep
(single beep) every 4 seconds until a transmitter signal is again received. Press the MODE button on the transmitter to
reset the receiver and the system will be back to normal operation.
The OUT-OF-RANGE SAFETY ALERT will be triggered when the transmitter is out of range again or the transmitter’s
low battery, batteries fail, batteries removed.
SETTING THE DESIRED ROOM TEMPERATURE
To set the DESIRED room temperature, press the MODE button to place transmitter into THERMO mode (Fig. 6), the
“THERMO” must be displayed on the LCD screen. Then press the “＋” and “－” buttons to increase or decrease desired
room temperature. The MAX. set temperature is 99° F (32° C), MIN. is 45° F (6° C). REMINDING: To extend battery
lifespan, the changes of ROOM temperature are detected and updated (send) to transmitter automatically every two
minutes only.
TEMPERATURE DIFFERENTIAL (variation “SWING”)
The THERMO mode on the transmitter operates with TEMPERATURE DIFFERENTIAL (also called variation “SWING”).
A smaller SWING increases the number of cycles so the room temperature is updated more often which consume more
battery power. A larger SWING decreases the number of cycles, so the tolerance of ROOM temperature is larger, but
can save some battery. The factory default setting for the SWING is 2 which means a temperature variation of +/- 2°F
(1°C) between SET temperature and ROOM temperature, which determines when the system will be ON or OFF. There
are three SWING numbers for user’s choice: +/- 1°F (0.5°C), +/- 2°F (1°C) , and +/- 3°F (1.6°C). See Fig. 17
