COMMUNICATION SAFETY FEATURE IN TRANSMITTER
This SKYTECH series remote controls have a COMMUNICATION – SAFETY function built into the software. It provides
an extra margin of safety when the TRANSMITTER is out of the normal 20-foot operating range of the receiver.
The COMMUNICATION – SAFETY feature operates in the following manner for all OPERATING MODES: ON/THERMO/
OFF.
At all times and in all OPERATING MODES, the transmitter sends an RF signal every fteen (15) minutes, to the receiver,
indicating that the transmitter is within the normal operating range of 20-feet. Should the receiver NOT receive a
transmitter signal every 15 minutes, the IC software, in the RECEIVER will begin a 2-HOUR (120-minute) countdown
timing function. If during this 2-hour period, the receiver does not receive a signal from the transmitter, the receiver will
shut down the replace being controlled by the receiver. The RECEIVER will then emit a series of rapid “beeps” for a
period of 10 seconds. Then after 10 seconds of rapid beeping, the RECEIVER will continue to emit a single “beep” every
4 seconds until a transmitter signal is again received. The intermittent 4 second beeping will go on for as long as the
receiver’s batteries last which could be in excess of one year.
To “reset” the RECEIVER and operate the replace system, you must press the MODE button on the transmitter. The
word ON must display on the LCD screen. By turning the system to ON, the COMMUNICATION SAFETY operation is
overridden and the system will return to normal operation depending on the MODE selected at the transmitter.
The COMMUNICATION SAFETY feature will reactivate should the transmitter be taken out of the normal operating range
or should the transmitter’s batteries fail or be removed.

SETTING THE DESIRED ROOM TEMPERATURE
This remote control system can be thermostatically controlled when the transmitter is in THERMO mode (THERMO must
be displayed on the screen). To set the DESIRED room temperature, press the MODE button to place transmitter into
THERMO mode (Fig. 17), then press the UP or DOWN
button to select desired room temperature. The highest SET
temperature is 99° F (32° C); the lowest SET temperature is
45° F (6° C).
OPERATIONAL NOTE: TO CONSERVE BATTERY POWER, CHANGES IN ROOM TEMPERATURE ARE AUTO-
MATICALLY UPDATED EVERY TWO MINUTES TO THE TRANSMITTER.
The Thermo Mode on the transmitter operates the appliance whenever the ROOM TEMPERATURE varies a certain
number of degrees from the SET TEMPERATURE. This variation is called the “SWING” or TEMPERATURE
DIFFERENTIAL. The normal operating cycle of an appliance may be 2-4 times per hour depending on how well the
room or home is insulated from the cold or drafts. A smaller “swing number” increases the number of cycles so the room
temperature is more constant. A larger “swing number” decreases the number of cycles, which saves energy, in most
cases. The factory setting for the “swing number” is 2. This represents a temperature variation of +/- 2° F (1° C) between
SET temperature and ROOM temperature, which determines when the replace will be activated. The “SWING” number
values are: 1=+ 1° F (.5° C), 2= + 2° F (1° C) and 3 = + 3° F (1.6 C).
