Users Manual

RCTHL Thermostatic HI/LO Remote Control INSTALLATION AND OPERATING INSTRUCTIONS This hi/lo remote control system provides a safe, reliable, and user-friendly remote control to power up to a 6 VDC servo motor or solenoid gas valve system (Maxitrol Gas Valve). Always check the appliance home owner’s manual for additional information, or warnings regarding accessory installation before connecting this remote control system. Carefully inspect the contents for shipping damage. If any parts are missing or damaged, immediately contact the dealer from whom you purchased the kit. Do not attempt to install any part of the kit unless all parts are in good condition. Please keep this manual for future reference.

Wiring must conform to appliance requirements and building codes/ordinances as required by local and national code authorities having jurisdiction. • Do not short (or jumper) across the gas valve terminals to test the remote control installation. This could damage the unit and void the warranty. • This remote control system should only be used as described in this manual. Any other use is not recommended and will void the warranty. Due to the sensitive temperature monitoring components in the transmitter, it is necessary to allow the transmitter to stabilize to room temperature before accurate room temperatures are displayed. If the transmitter is activated from a severe cold condition, allow 15 minutes for accurate temperature readings to appear on the LCD. Turn appliance OFF and allow to cool before installing or servicing. DO NOT connect 110-120 VAC wiring to the milli-volt gas control valve. The remote operator must be installed exactly as outlined in these instructions. Read all instructions completely before attempting installation. Follow instructions carefully during installation. Any modification of components will void the warranty and may cause a fire hazard. Low battery power in the transmitter or receiver can affect the operation of the remote control in the AUTO mode. In some cases the unit may not cycle off when the target temperature is reached. INSTALLATIONS Remote Receiver: The remote receiver may be wall mounted or installed in the appliance per the appliance homeowner’s manual. Refer to the Homeowner’s Manual for special installation instructions.If wall mounted, the remote receiver must be installed in a junction box with cover plate provided. Failure to follow the installation instructions found in the appropriate Homeowner’s Manual will void the warranty and may cause a fire hazard. Installing Batteries: The remote receiver uses four (4) "AA"- size batteries. To install batteries, 1. Remove the push buttons by gently pulling straight out. 2. Use your thumb and index finger to gently pull down the L-bracket. 3. Open the battery door by pressing the two tabs located on the door. 4. Install the batteries as indicated in the receiver cover. 5. Close the battery door until the door tab snaps in place. 6. To install the receiver into a wall junction box, install the receiver with the screws provided. 7. If you decided to install the receiver into the appliance, reinstall the L-bracket. 8. Gently, install the push buttons back to the receiver stem. 9. The batteries should be replaced at least once every 6 months or when the battery indicator flashes. Installing Wire: This system comes with an 18 inch pre-assembled wire assembly. Insert the white terminal to the back of the receiver. The terminal wire block can only be installed one way. Do not force the termi- nal plug onto the receiver. Follow the homeowner’s manual for connecting the 1/4",3/16", and two (2) 1/8" female spade terminals to the valve. For applications longer than 18 inches, use 18 gauge wire, 105ºC rated, with no splices. Connect to the the 1/4", 3/16", and two (2) 1/8" female spade wiring terminals. Wire can be no longer than 20 feet. Make sure that the wires do not contact the appliances any place other than at the terminals. Exposure to temperatures higher than 105C (250ºF) may cause the receiver to malfunction or fire hazard. Setting Privacy Security Code on Transmitter and Receiver The remote receiver and transmitter security codes are preset at the factory. A privacy code can be set into the system to prevent accidental operation by other transmitters in the vicinity using the following procedure: 1. Press the two push buttons on the receiver simultaneously and then press ON/HI button on the transmitter once. 2. The receiver LED will blink twice and the security code is now set. 3. The system is ready to operate. Reset B…
