MATCHING SECURITY CODES

It may be necessary to program the remote receiver to the security code of the transmitter upon initial use if batteries are replaced, or if a replacement transmitter is purchased from your dealer. To program the remote receiver:

  1. Verify that the receiver is connected to 110-120VAC power. Verify that the batteries are installed in the remote transmitter.
  2. Set the slide button on the receiver to the REMOTE position.
  3. Press and release the LEARN button on the top of the remote receiver. The receiver will beep to confirm it is ready to accept the pairing code from the remote transmitter.
  4. Press the MODE button on the transmitter. Several beeps indicate the transmitter’s code has been programmed into the receiver. When an existing receiver is matched to a new transmitter, the new security code will overwrite the old one.

NOTE: If no “beeping” occurs when the LEARN button is pressed and released, take the following steps: Verify that the receiver is connected to 110-120VAC power. If the receiver still does not provide “beeping” feedback and will not pair to the new remote transmitter, press and hold the LEARN button for 10 seconds until the receiver emits three long “beeps” to confirm the security code memory has been cleared. Once the memory is cleared, follow steps 2 and 3 above to program the transmitter to the receiver.

OPERATING INSTRUCTIONS

To operate the system, press the MODE button (Figure 5) on the transmitter to select the operational MODE desired.

  • ON indicates the system is on, either manually, timed or thermostatically.
  • THERMO indicates the system will automatically cycle ON/OFF, depending on programmed set temperature.
  • OFF indicates the entire system is turned off.

Transmitter Settings

  • Flip open the plastic cover on the front of the transmitter to expose the “SET” buttons.
  • NOTE: Flashing numbers on the display indicate the system is waiting for 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.

Setting the Clock

  1. Press and hold the TIMER/TIME button on the transmitter for more than two seconds. The hour digit(s) will begin flashing (see Figure 5, Location #6).

  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 the setting button is not pushed within 15 seconds.

Setting Desired Room Temperature –

Thermo Operations
This remote control system can be thermostatically controlled when the transmitter is in the THERMO mode. (THERMO must be displayed on the screen). The transmitter will “sense” the room temperature every two minutes automatically turning the fireplace ON or OFF thermostatically.
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 (37º C). The lowest SET temperature is 45º F (7º C).

NOTE: To prevent repeated thermo-cycling of the gas appliance, the sensing unit in the transmitter will only activate the remote receiver when the temperature change exceeds 1º F (1/2º 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 transmitter in direct sunlight, for example, will cause it to read the room temperature higher than it 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 transmitter. The words TIMER and 0:15 flash on the screen (see Figure 5, Location #2).
  2. Press the UP and DOWN buttons 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 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.

NOTE: When the timer is used in the THERMO mode, the THERMO operation will discontinue when the “time” has expired.

Low/Battery Indicator
An “X” outlined by a battery on the right side of the LCD screen will appear when battery power has dropped significantly. At this time, approximately two weeks of battery power remain.

Child Proof Lockout (CP)
The transmitter contains a “Child Proof” lockout feature that prevents unauthorized use of the remote control. To access the “Child Proof” activation button, remove the cover on the BACK of the transmitter. To activate LOCKOUT:

  1. Press and hold the “setting button” for 5 seconds. The letters CP will be displayed on the LCD screen (see Figure 6). This prevents the activation of the fireplace. When any function button is pressed ON/OFF etc. the letter CP will display on the LCD screen.

To deactivate LOCKOUT:

  1. Press and hold the “setting button” for 5 seconds. The LCD will display CP until 5 seconds have elapsed, and then the LCD screen will return to its normal state.

TRANSMITTER SAFETY FEATURES

  • It is recommended that the TRANSMITTERS always be located within a 20-foot operating range of the fireplace, preferably in the same room in which the fireplace system is located. The TRANSMITTER features several safety features that alert the user when the TRANSMITTER is placed outside the 20-foot normal operating range. Communication-Safety Features
  • This remote control has a COMMUNICATION-SAFETY function built into its software. It provides an extra margin of safety when the TRANSMITTER is out of the normal 20 foot operating range of the receiver. It is also activated when the batteries become weak or are removed from the transmitter.
  • In the THERMO-UPDATING feature (only in the THERMO or TIMER modes) the transmitter normally reads the ROOM temperature every 2 minutes. In addition to checking the temperature, the transmitter sends a signal to the receiver indicating that the transmitter and its batteries are still active.
  • In the COMMUNICATION-SAFETY feature, at all times and in all OPERATING MODES the transmitter sends a signal every fifteen (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 (COMMUNICATION-SAFETY feature), the RECEIVER will begin a 2-HOUR (120 minute) countdown timing function. If during these 2 hours, the receiver does not receive a signal from the transmitter, the RECEIVER will shut down the fireplace being controlled by the receiver.
  • The RECEIVER will then emit a series of rapid “beeps”.
  • Then, after 10 rapid “beeps”, 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 indefinitely until reset.

To “reset” the RECEIVER and operate the fireplace system:

  1. Press the MODE button on the transmitter. The word ON must be displayed on the LCD screen. The COMMUNICATION-SAFETY operation is overridden and the system will return to normal operation depending on the MODE selected at the transmitter.
    • We recommend the user check the batteries in the TRANSMITTER to make sure the voltage is no less than 2.7 volts.

Auto Shutdown
This remote control has an Auto Shutdown feature incorporated into its system. When the transmitter MODE is in the ON position the fireplace will continuously operate for 9 hours. After 9 hours, the fireplace will shut down. To relight the fireplace:

  1. Press the MODE button.
    • The Auto Shutdown signal comes from the transmitter. The transmitter must be positioned within a 20-foot operating range for the Auto Shutdown feature to operate.

SYSTEM CHECK

Standing Pilot Valves
Light the appliance following the lighting instructions that came with the fireplace. Confirm that the pilot flame is on. It must be in operation for the main gas valve to operate.

  1. Slide the 3-position button on the remote receiver to the ON position. The main gas flame (i.e., the fire) should ignite.
  2. Slide the button to OFF. The flame should extinguish (the pilot flame will remain on).
  3. Slide the button to REMOTE (the center position), then press the MODE button on the transmitter to change the system to ON. The main gas flame should ignite.
  4. Press the MODE button on the transmitter to change the system to OFF. The flame should extinguish (the pilot flame will remain on).
  5. Press the MODE button on the transmitter to change the system to THERMO.
  6. Advance the SET temperature on the transmitter to a temperature of at least 2º F (1º C) above the ROOM temperature displayed on the LCD screen and the system flame will ignite.
  7. Set the SET temperature to at least 2º F (1º C) below the room temperature and the system flame will extinguish. Thereafter, it should continue to cycle on and off thermostatically approximately every two minutes as the ROOM temperature changes, but only when the temperature differential between ROOM and SET temperatures differs at least 2º F (1º C). The 2º F (1º C) F differential is the factory setting.

Electronic Ignition System

  1. Slide the 3-position button on the remote receiver to the ON position. The spark electrode should begin sparking to ignite the pilot (the pilot may ignite after only one spark). After the pilot flame is lit, the main gas valve should open and the main gas flame should ignite.
  2. Slide the button to OFF. The main gas flame and pilot flame should BOTH extinguish.
  3. Slide the button to REMOTE (the center position).
  4. Then press the MODE button on the transmitter to change the system to ON. The spark electrode should begin sparking to ignite the pilot. After the pilot is lit, the main gas valve should open and the main gas flame should ignite.
  5. Press the MODE button on the transmitter to OFF. The main gas flame and pilot flame should BOTH extinguish.
  6. Press the MODE button on the transmitter to change the system to THERMO.
  7. Advance the SET temperature on the transmitter to temperature of at least 1º F (-17º C) above the room temperature displayed on the LCD screen and the system flame will ignite.
  8. Set the SET temperature to at least 2º F (1º C) below the room temperature and the system will extinguish. Thereafter, it should continue to cycle on and off thermostatically approximately every two minutes as the ROOM temperature changes, but only when the temperature differential between ROOM and SET temperatures differ at least 2º F (1º C). The 2º F (1º C) differential is the factory setting.

Timer Operation
The countdown timer will operate in either the manual ON or THERMO mode. Once the fireplace system is in operating mode, set the countdown timer to turn off in 15 minutes. The timer function will allow the operation to continue until the “countdown time” on the LCD screen expires. After 15 minutes elapses, the system should turn off.

GENERAL INFORMATION
