TRANSMITTER WALL CLIP
The transmitter can be hung on a wall using the clip provided. If the clip is
installed on a solid wood wall, drill 1/8" pilot holes and install with the screws
provided. If it is installed on a plaster/wallboard wall, first drill two 1/4" holes into
the wall. Then use a hammer to tap in the two plastic wall anchors flush with the
wall; then install the screws provided.
BATTERY LIFE
Life expectancy of the alkaline batteries in the THR-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 5.5volts. The transmitter should operate with as little
as 2.5 volts battery power.
TROUBLE SHOOTING
If you encounter problems with your fireplace system, the problem may be with the fireplace itself or it could be with the THR-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:
•
Make sure the batteries are correctly installed in the RECEIVER. One reversed battery will keep receiver from operating properly.
•
Check battery in TRANSMITTER to make sure contacts are touching (+) and (-) ends of battery. Bend metal contacts in for tighter
fit.
•
Be sure RECEIVER and TRANSMITTER are within 20'-25' operating range.
•
Keep RECEIVER from temperatures exceeding 130° F. Battery life shortened when ambient temperatures are above 115° F.
•
If RECEIVER is installed in tightly enclosed metal surround, the operating distance will be shortened.
NOTE.
•
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).
