Setting ºF/ºC Scale
The factory setting for temperature is degrees Fahrenheit
(ºF). To change this setting to degrees Centigrade (ºC):
1. Remove the battery cover on the back of the transmit-
ter and locate the “setting button” at the top center of
battery compartment (see Figure 8).
2. Push setting button and ºF will begin flashing on the
LCD screen (see Figure 7, Location #8).
3. Push the DOWN button on the transmitter to change ºF
to ºC.
4. Push “setting button” on transmitter and Centigrade (ºC)
degree readings will display on LCD screen.
5. Repeat this process to change back to Fahrenheit (ºF)
reading, this time pushing the UP button.
NOTE:
LCD
screen will return to normal state if setting button is not
pushed within 15 seconds.
Setting Desired Room Temperature -
Thermo Operations
This remote control system can be thermostatically con-
trolled when the transmitter is in the THERMO mode.
(THERMO must be displayed on the screen). The transmit-
ter will “sense” the room temperature every two minutes
automatically turning the fireplace ON or OFF thermostati
-
cally. To set the desired room temperature:
1. Press the MODE button to place the transmitter into
THERMO mode. THERMO ON or OFF will display.
2. Press the UP or DOWN button to select the desired room
temperature. The highest SET temperature is 99º F (32º
C). The lowest SET temperature is 45º F (6º C).
NOTE:
To prevent repeated thermo-cycling of the gas ap-
pliance, the sensing unit in the transmitter will only activate
the remote receiver when the temperature change exceeds
2º F (1º C) above or below the SET (desired) temperature.
When the transmitter is in the THERMO mode, it should be
kept away from direct sources of heat such as fireplaces,
incandescent lighting and direct sunlight. Leaving the trans-
mitter in direct sunlight, for example, will cause it to read
the room temperature higher than it actually is.
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 LCD screen).
1. Press and release the TIMER/TIME button on the trans-
mitter. The word TIMER and 0:15 flash on the screen
(see Figure 7, Location #2).
2. Press the UP and DOWN button to begin advancing
through each of the countdown time options. Available
countdown times are 15 min, 30 min, 45 min, 1 hour,
1 hr 30 min, and each additional half hour up to nine
hours.
3. To set the TIMER, press the SET button on the transmit-
ter. 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.
NOTE:
When the timer is used in the THERMO mode,
the THERMO operation will discontinue when the “time”
has expired.
Operating the Fan -
Operates in ON or THERMO mode
This remote control system has the capability of operat-
ing a 110 VAC fan or blower system that may be included
with your gas fireplace. The fan will only operate when the
transmitter is in the ON or THERMO mode. (THERMO or
ON must be displayed on LCD screen).
1. To turn fan ON, press and release the FAN button on
the transmitter (see Figure 7, Location #9). The fan will
operate at HI speed, and fan blade icon will appear on
LCD screen.
2. To change fan speed to MED, press and release FAN
button again. To change fan speed to LO, press and
release FAN button again.
3. To turn fan OFF, press and release FAN button again.
Fan blade icon will disappear from LCD screen.
