WT-2R INSTALLATION AND OPERATING INSTRUCTIONS
SINGLE-FUNCTION WIRELESS REMOTE CONTROL SYSTEM
FOR OPERATING VALVES WITH ON/OFF LATCHING SOLENOIDS
INTRODUCTION
This remote Wireless Wall Timer system was developed to provide a safe, reliable, and user-friendly remote control system for gas
heating appliances. The system can be operated manually from the transmitter. The system operates on one of 65,536 security codes
that are programmed into the transmitter at the factory.
WALL TIMER
The wall timer operates on a (2) 3V button cell batteries (included) made
specifically for remote controls and electronic lighters. Before using the wall
transmitter, install the two (2) 3V button cell batteries. Follow instructions below.
The wall timer has a 30 min, 60 min, 120 min, and OFF buttons. When any of the
buttons on the wall timer is pressed, a signal light on the wall timer illuminates
briefly to verify that a signal has been sent. If the signal light does not illuminate,
check the batteries. Upon initial use, there may be a delay of five seconds before
the remote receiver will respond to the wall timer.

WALL MOUNTING THE TIMER
1. The wireless wall timer must be located within 20’ of the receiver, this is
the normal operational distance.
2. Remove face from backing plate by insetting a small screwdriver into
the small slot at the top or bottom of the faceplate as shown to the right
then snap OFF.
3. Locate the (2) two mounting holes and mark the holes on the wall
4. Use the (2) two dry wall anchors and screws (that are supplied) to
mount the base plate to the wall as shown.
5. The wall transmitter can also be mounted onto an existing (Plastic)
electrical box.
6. Base plate should be mounted level on the wall for best operation.
REMOTE RECEIVER IMPORTANT
THE REMOTE RECEIVER SHOULD BE POSITIONED WHERE AMBIENT
TEMPERATURES DO NOT EXCEED 130° F.
The remote receiver (right) operates on four 1.5V AA-size batteries. It is
recommended that ALKALINE batteries be used for longer battery life and
maximum microprocessor performance. IMPORTANT: New or fully charged
batteries are essential to proper operation of the remote receiver as a latching
solenoid power consumption is substantially higher than standard remote control
systems.
NOTE: The remote receiver will only respond to the transmitter when the 2-position slide button on the remote receiver is in the
REMOTE position. The remote receiver houses the microprocessor that responds to commands from the transmitter to control system
operation.
FUNCTIONS:
1. With the slide switch in the REMOTE position, the system will only
operate if the remote receiver receives commands from the transmitter.
Upon initial use or after an extended period of no use, the ON button may
have to be pressed for up to three seconds before activating solenoid. If the
system does not respond to the transmitter on initial use, see Matching
Security Codes.
2. With the slide in the OFF position, the system is off.
3. It is suggested that the slide switch be placed in the OFF position if
you will be away from your home for an extended period of time.
Placing the slide switch in the OFF position also functions as a safety
"lock out" by both turning the system OFF and rendering the
transmitter inoperative.
INSTALLATION INSTRUCTIONS WARNING
DO NOT CONNECT REMOTE RECEIVER DIRECTLY TO 110-120VAC POWER. THIS WILL BURN
OUT THE RECEIVER. FOLLOW INSTRUCTIONS FROM MANUFACTURER OF GAS VALVE FOR
CORRECT WIRING PROCEDURES. IMPROPER INSTALLATION OF ELECTRIC COMPONENTS
CAN CAUSE DAMAGE TO GAS VALVE AND REMOTE RECEIVER, WHICH IS NOT COVERED BY
WARRANTY.
INSTALLATION
NOTE: INSTALLATIONS IN THE OPTIONAL CERAMIC LOG HOUSE (ITEM #RH2) IS HIGHLY RECOMMENDED.

The remote receiver can be mounted on or near the fireplace hearth. PROTECTION FROM EXTREME HEAT IS VERY IMPORTANT.
Like any piece of electronic equipment, the remote receiver should be kept away from temperatures exceeding 130º F inside the
receiver case. Battery life is also significantly shortened if batteries are exposed to high temperatures.
Make sure the remote receiver switch is in the OFF position. For best results it is recommended that 18 gauge stranded wires should
be used to make connections and no longer than 20 ft.
WIRING INSTRUCTIONS
CONNECTING THE RECEIVER TO A VALVE WITH THE LATCHING SOLENOID
1. Connect the BLACK 18 gage stranded wire with the ” female terminal from the receiver to the BLACK wire with the 1/4” male
terminals from the valve solenoid.
2. Connect the RED 18 gage stranded wire with the ” female terminal from the receiver to the RED wire with the 1/4” male terminals
from the valve solenoid.
3. After receiver wires are connected to the valve solenoid wire make sure the receiver shield is located over the receiver and then
locate the receiver in an area that will not exceed the 130° F.
IMPORTANT NOTE: Operation of these controls is dependent on which wire is attached to which terminal. If operation of control
does not correspond to operating buttons on transmitter, reverse wire installation at the receiver or at the control.
NOTE: Up to 6.3 VDC of power is provided at the receiver terminal.
THERMOSTAT-SAFETY FEATURE BPR-1 RECEIVER
When the ambient temperature at the THERMISTOR, inside the receiver case, reaches 130°F, the THERMISTOR will automatically
send 2 pulses of power to the off terminal on the valve to shut the fireplace system off and the RECEIVER will begin emitting a series of
2 "beeps" every 4 seconds. When the ambient temperature, at the RECEIVER, drops between 120° F and 130° F, the user can
reactivate the fireplace by pushing either button on the transmitter. When any transmitter button is pressed, the THERMISTOR "resets"
itself and the fireplace will begin operating again. However, the "beeping" will continue, if the ambient temperature remains between
120° F and 130° F. This "beeping" alerts the user that the RECEIVER should be repositioned so the ambient temperature drops below
120° F.
When the temperature drops below 120° F, the "beeping" will cease, providing the user has "reset" the THERMISTOR by pushing
either transmitter button to operate the fireplace. Allow sufficient time for receiver to cool below 120° F, and then press transmitter
button to stop beeping.
GENERAL INFORMATION
MATCHING SECURITY CODES
Each transmitter can use one of 65,536 unique security codes. It may be necessary to press the LEARN button on the remote receiver
accept the transmitter security code upon initial use, if batteries are replaced, or if a replacement transmitter is purchased from your
dealer or the factory. In order for the receiver to accept the transmitter security code, be sure the slide button on the receiver is in the
REMOTE position; the receiver will NOT "LEARN" if the slide switch is in the OFF position. Press the LEARN button on the remote
receiver to accept the transmitter security code Push and Release the LEARN button on the front of the remote receiver and then
Press any button on the transmitter. A change in the beeping pattern, at the receiver, indicates the transmitter's code has been
accepted into the receiver. When an existing receiver has accepted the new transmitter, the new security code will overwrite the old
one.

The microprocessor that controls the security code matching procedure is controlled by a timing function. If you are unsuccessful in
matching the security code on the first attempt, wait 1 - 2 minutes before trying again--this delay allows the microprocessor to reset its
timer circuitry--and try up to two or three more times.
OPERATION
1. This remote wall timer will operate the gas valve’s latching solenoid to open the gas flow to full ON.
2. When the ON button is depressed the transmitter sends a RF signal to the receiver. The receiver then sends a
pulse of 6 volts of power to the solenoid. The solenoid then opens the gas flow to the burner then to full ON.
3. When the OFF button is depressed the transmitter sends a RF signal to the receiver. The receiver then sends a
pulse of 6 volts of power to the solenoid. The solenoid then closes the gas flow to the burner then to full OFF.
4. The remote wall timer will only work with the hand held transmitter. The receiver slide switch is only for positive OFF or REMOTE
operation.
NOTE: Extensive use of the Latching Solenoid (ON/OFF) will reduce the receiver's battery life significantly.
BATTERY LIFE
Life expectancy of the alkaline batteries in the WT-2R can be up to 12 months depending on use of the solenoid function. Replace all
batteries annually. When the transmitter no longer operates the remote receiver from a distance it did previously (i.e., the transmitter's
range has decreased) or the remote receiver does not function at all, the batteries should be checked. It is important that the remote
receiver batteries are fully charged, providing combined output voltage of at least 5.0 volts. The transmitter should operate with as little
as 2.4 volts battery power. NOTE: Extensive use of the Solenoid will reduce the receiver's battery life significantly.
TROUBLE SHOOTING
If you encounter problems with your fireplace system, the problem may be with the fireplace itself or it could be with the WT-2R remote
system. Review the fireplace manufacturer's operation manual to make sure all connections are properly made. Then check the
operation of the remote in the following manner:
1. Make sure the batteries are correctly installed in the RECEIVER. One reversed battery will keep receiver from operating properly.
2. Check battery in TRANSMITTER to make sure contacts are touching (+) and (-) ends of battery. Bend metal contacts in for tighter
fit.
3. Be sure RECEIVER and TRANSMITTER are within 20'-25' operating range.
4. Keep RECEIVER from temperatures exceeding 120° F. Battery life shortened when ambient temperatures are above 115° F.
5. If RECEIVER is installed in tightly enclosed metal surround, the operating distance will be shortened.
NOTE:
1. A receiver located in an area, where the ambient temperature inside the case exceeds 130° F, will cause the THERMOSTAT-
SAFETY feature to cut in, requiring you to reposition the receiver to stop the warning beeps, and to "reset" the receiver's operation.
2. Due to handling and shipping of the unit, handling or dropping of the transmitter by the customer, and/or heat conditions at the
receiver, some receivers may need an occasional frequency adjustment. This adjustment is made to improve the communication
and operating distance between the transmitter and the receiver. Follow the steps below for making the adjustment.
FREQUENCY (DISTANCE) ADJUSTMENT PROCEDURE
RECEIVER ADJUSTMENT
1. To adjust at the receiver, use a small slotted screwdriver. Turn the adjustment (ADJ)
screw counter-clockwise about 5° or maximum of 1/8 turn. This should correct the
distance problem.
2. If that does not correct the problem, return adjustment screw to original position and then
turn adjustment screw clockwise.
This adjustment is like tuning your radio. If you keep turning the adjustment screw, in either
direction, you will go past the proper setting (tuning).
