INSTALLATION AND OPERATING INSTRUCTIONS 
INTRODUCTION 
This SKYTECH remote control system was developed to provide a safe, reliable, and 
user-friendly remote control system for gas heating appliances. The system can be 
operated thermostatically or manually from the transmitter. The system operates on 
radio frequencies (RF) within a 20”range using non-directional signals. The system 
operates one of 256 security codes that are user programmable; the remote receiver’s 
code must be matched to that of the transmitter prior to initial use. 
Review COMMUNICATION SAFETY SECTION under TRANSMITTER 
section and THERMO SAFETY SECTION under REMOTE RECEIVER section. 
These signal/temperature safety features shut down the fireplace system when a 
potentially unsafe condition exists. 
The transmitter operates on 2 AAA-size 1.5V 
batteries. It is recommended that ALKALINE 
batteries always be used for longer battery life and 
maximum operational performance. 
IMPORTANT: New or fully charged batteries are 
essential for proper operation of the multi-function 
transmitter. Insert 2 AAA-size 1.5V batteries into the 
battery compartment on the back of the transmitter, 
positioning the (+) and (-) ends of the batteries as 
indicated on the casing. When the batteries are 
inserted, the screen at right (with similar numbers) 
will display. 
Note: If a LOW battery icon appears on the 
screen, check the position of the batteries; a 
reversed battery will not activate transmitter. 
Note: Due to the sensitive 
temperature-monitoring components in the 
transmitter, it may be necessary to allow the 
transmitter to stabilize to room temperature 
before accurate room temperatures are displayed on the screen. If the transmitter is

Slide down the plastic cover on the front of 
the transmitter to expose the “SET” buttons. 
The Slide cover protects the SET buttons from 
being changed accidentally. Close the cover 
after completing the following 
settings/programming. 
Flashing numbers on the display indicate the 
system is awaiting user input, such as using 
the UP and DOWN buttons to program a new 
setting. If no change is made to flashing digits within 15 seconds, the system will 
complete the procedure last programmed and reset the display to its normal state. 
1.  Press and hold the TIME /TIMER button 
on the transmitter for more than two 
seconds. The hour digit(s) will begin 
flashing. 
2.  Press the UP or DOWN button until the 
desired hour is displayed in AM or PM. 
3.  After setting the desired hour, press and 
release the TIME/ TIMER button again to 
set the minutes; the minute digits will 
begin flashing. 
4.  Press the UP or DOWN button until the 
desired minutes are displayed. 
5.  Press the SET button on the transmitter to 
stop the time digits from flashing and set 
the time. The time digits will cease 
flashing, indicating the clock has been successfully set.   
SETTING  ℉/℃ SCALE 
The factory setting for temperature is  ℉. To change this setting to  ℃, first press and 
hold the UP button and the DOWN button on the transmitter at the same time. Follow 
this same procedure to change from  ℃ back to  ℉. When changing between the  ℉ 
and  ℃ scales, the temperature in the SET frame defaults to the lowest temperature 
(45℉, or 8℃). The highest SET temperature is 99° Fahrenheit (37° Celsius).

SETTING DESIRED ROOM TEMPERATURE 
This remote control system can be 
thermostatically controlled when the 
transmitter is in the THERMO mode 
(THERMO must be displayed on the 
screen). To set the DESIRED room 
temperature, press the MODE button to 
place the transmitter into THERMO mode, 
then press the UP or DOWN button to 
select the desired room temperature. The 
highest SET temperature is 99° 
Fahrenheit (37° Celsius). 
OPERATIONAL NOTE: TO CONSERVE BATTERY POWER, CHANGES IN 
ROOM TEMPERATURE ARE AUTOMATICALLY 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℉ (1℃) between SET temperature and ROOM temperature, which 
determines when the fireplace will be activated. The “SWING” number values are: 
1=±1℉ (.5℃), 2=±2℉ (1℃) and 3=±3℉ (1.6℃). 
SETTING THE TEMPERATURE SWING (TEMPERATURE DIFFERENTIAL) 
1.  To change the temperature “SWING” 
setting (1-3), press the TIME/ TIMER and 
DOWN buttons simultaneously to display 
the current “SWING” setting in the SET 
TEMP frame. The letter “S” will display in 
the ROOM TEMP frame on the LCD 
screen. 
2.  Press the UP or DOWN button to change

the temperature differential or “SWING” (1-3). See above for 1-3 “SWING” 
temperature valves. 
3.  To store the “swing number” press the SET button or allow 15 seconds to lapse, 
and the new “swing number” will be automatically programmed. 
MANUAL CHECK OF “SWING” OR TEMPERATURE DIFFERENTIAL 
The operation of the factory set “THERMO SWING” can be checked by adjusting the 
SET TEMP 2℉ above or below the room temperature. This will cause the system to 
turn OF or OFF. Normally the system will only respond to temperature changes every 
two minutes. Manually changing the SET temperature will activate the system in less 
than 10 seconds. IF the “SWING” is changed, then a new room temperature 
differential will respond. Factory setting of “SWING” temperature is 2℉. 
SETTING THE COUNTDOWN TIMER 
This remote control system can operate 
with a built-in countdown timer when the 
transmitter is in the ON or THERMO 
modes (THERMO or ON must be 
displayed on the screen). 
1.  Press and release the TIME/ TIMER 
button on the transmitter. The word 
TIMER and 0:15 flash on the screen. 
2.  Press the UP or DOWN button on the 
transmitter to begin advancing through 
each of the countdown time options. Available countdown times are 15 minutes, 
30 minutes, 45 minutes, 1 hour, 1 hour 30 minutes, 2 hours, 2hours 30 minutes, 
and each additional half-hour up to nine hours.   
3.  To set the TIMER press the SET button on the transmitter if the system is ON. It 
will remain on until the time has expired. If the system is in the THERMO mode, 
it will cycle on and off as the room temperature requires until the “time” has 
expired. 
OPERATIONAL NOTE: When the timer is used in the THERMO mode, the 
THERMO operation will discontinue when the “time” has expired.

The low battery icon on the left side of the 
LCD screen will appear when battery power 
has dropped significantly. At this time, 
approximately two weeks of battery power 
remains until the transmitter may experience 
partial or complete loss of functions. 
CHILDPROOF  “LOCK-OUT” –(CP) 
This SKYTECH remote control includes a 
CHILDPROOF “LOCK-OUT” feature that allows the user to “LOCK-OUT” 
operation of the appliance, from the TRANSMITTER. 
SETTING “LOCK-OUT” –(CP) 
1.  To activate the “LOCK-OUT” feature, 
press and hold the UP and TIME/TIMER 
buttons, together, for 5seconds. The letters 
CP will appear in the TEMP frame on the 
LCD screen. 
l To disengage the “LOCK-OUT”, press and 
hold the UP and TIMER buttons, together 
for 5 seconds or more, and the letters CP 
will disappear from the LCD screen and 
the transmitter will return to its normal 
operating condition. 
NOTE: If the appliance is already operating in the ON or THERMO MODES, 
engaging the “LOCK-OUT” will not cancel the operating MODE. Engaging the 
“LOCK-OUT” prevents only the manual operation of the TRANSMITTER. If in the 
auto modes, the THERMO operation will continue to operate normally. To totally 
“LOCK-OUT” the operation of the TRANSMITTER’S operating signals; the 
transmitter’s MODE must be set to OFF.   
TRANSMITTER 
The SKYTECH remote control operates, on RF (radio frequency) signals that are sent 
by the TRANSMITTER (remote) to the RECEIVER that operates the appliance. It is 
recommended that the TRANSMITTER always be located within the 20 foot 
operating range, preferably in the same room in which the appliance is located.

THERMO UPDATING FEATURE -TRANSMITTER - (T/S -TX) 
This SKYTECH remote control has a THERMO UPDATING Feature built into its 
software. The THERMO UPDATING Feature operates in the following manner, but 
only in the THERMO MODES: 
    The transmitter normally reads the ROOM temperature every 2 minutes checking 
the ROOM temperature against the SET temperature and then sends a signal to 
the receiver.
