It has a built-in thermostat. This all battery system operates independently of household current. The system operates on radio frequencies with a non-directional signals. The systems operating range is approximately 20-feet. The system operates on one of 10,000,000 security codes that are programmed into the transmitter at the factory, the remote receiver’s code must be matched to that of the transmitter prior to initial use. It is designed to be used with millivolt gas valves as a dry contact switch. The transmitter has ON and OFF and THERMOSTAT functions. If the LCD screen is not working, check the position of the transmitter’s battery. ON OFF SET LCD Screen ON-OFF Buttons Thermo/Set Button FRONT MODEL: BACK BACK FRONT ON OFF SET 1 2 3 1 ON - Operates unit to ON position, Manually ON. 2 OFF - Operates unit to OFF position, Manually OFF. 3 SET - Sets temperature in THERMO mode. 1 ROOM Temperature 2 ºF or ºC Icon 3 “ON” Flame Icon 4 THERMO Mode 1 2 3 THERMO 4 Liquid Crystal Display (LCD) The transmitter operates on (1) 3V Button Cell (included) that powers the RF signal. Before using the transmitter, the 3V battery must be installed into the battery compartment. Tools Needed: Small jewelers screwdriver To remove the battery holder from the bottom of the transmitter insert a small jewelers screwdriver into the notch at the bottom of the transmitter, then gently pry out the battery holder out. Once it is started, it will pull out with your fingers. Insert the 3-volt button cell battery in the battery holder with the plus (+) side up. See the drawings at the right. It is recommended that CR2032 lithium battery always be used for longer battery life and maximum operational performance.

THERMO THERMO-ON THERMO THERMO-OFF THERMO THERMO-SET Model: 4001TH-A TX REV. 3-31-20 Page 3 REMOTE RECEIVER The remote receiver operates on 4 AA-size 1.5V 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 for proper operation of the remote receiver. The remote receiver houses the microprocessor that responds to commands from the transmitter to control system operation. The remote receiver has a 3-position slide switch for selecting the MODE of operation: OFF/REMOTE/ON • With the slide switch in the ON position the system will remain on until the slide switch is placed in the OFF or REMOTE position. • With the slide switch in the REMOTE position (centered), the system will only operate if the remote receiver receives commands from the transmitter. If the system does not work see LEARNING TRANSMITTER TO RECEIVER Section. • With the slide switch in the OFF position the system is OFF. • 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 remote receiver inoperative.

Read all instructions completely before attempting installation. Follow instructions carefully during installation. Any modifications of the remote control or any of its components will void the warrant and may be pose a fire hazard. Do not connect any gas valve or electronic module directly to 110-120VAC power. Consult gas appliance manufacturer’s instructions and wiring schematics for proper placement of all wires. All electr…
