RWBMT9103CBUCellular Tank Monitor

OVERVIEW The WESROC ® Route Management System has been installed by your service provider. The tank transmitter measures the tank level and will transmit the tank level to the Base Unit whenever the level changes. The Base Unit allows you to observe your tank level from the comfort of your home, and it will periodically send your tank level to your service provider. WESROC ® RMS allows your service provider to supply you with the fastest and most accurate service possible. Never again will you have to go outside to check your tank level, nor will you wonder if your service provider knows the level of your tank, because now they do. The WESROC ® Route Management System will not interfere with other wireless devices in your home. The BASE UNIT must remain connected AC POWER in order for WESROC ® RMS to provide accurate tank levels to your service provider. It is imperative that you DO NOT RELOCATE OR UNPLUG any WESROC ® RMS device without first contacting your service provider to ensure uninterrupted service.

Keep cords hidden and secure so they do not pose a trip hazard. • Do not overload wall outlets or extension cords as this can result in a fire or electrical shock. • Do not disassemble any WESROC ® RMS device because this will void the warranty and may expose you to dangerous voltages or other risks. • Disconnect the Base Unit if a cord becomes damaged or frayed. • Do not use the Base Unit if there is a known gas leak. • The Base Unit is intended for INDOOR USE ONLY. IMPORTANT : Only use the power adapter provided. Using another adapter could seriously damage the Base Unit. Page 3 FEATURES • A large, bright display that can be easily read from across the room. The display can be adjusted to the appropriate brightness level for various lighting conditions or an auto-off feature can be selected which will automatically turn off the display after about 4 minutes of no activity. • The Base Unit’s electronics are housed in a durable enclosure, which can be tilted to accommodate different mounting configurations. The Base Unit can sit on a flat surface or be wall mounted. • If your tank level reaches a predetermined level, the Base Unit will immediately notify your propane supplier. • With the Auto-Update (AUTO) feature enabled, you will never need to set the time after a power failure or during daylight savings time changes. The Base Unit will automatically set the time when it sends your tank level to your service provider. • The indoor and outdoor (external temperature transmitter required) temperature can be displayed in either Fahrenheit or Celsius. • A Transmitter Activity Indicator is included in the Base Unit. The LED in the lower, right corner lights up when a transmitter is sending new information to the Base Unit. INSTALLATION of the WESROC ® RMS DELUXE BASE UNIT • The following are several items that will help you and your service provider determine the best location for the Base Unit: o Visibility: The Base Unit should be located where it is easy to view and access. o Power: The Base Unit requires 110V - AC to operate and should be placed near an electrical outlet. Make sure that the AC outlet is not connected through a switch because the Base Unit must be plugged into constant AC power to work correctly. o Temperature Accuracy: If you plan on using the indoor temperature display, the Base Unit should NOT be placed in direct sunlight, nor should it be placed near any heating or cooling source. o Tank Location: For best results, the Base Unit should be placed as close to the tank as possible. This may not always be possible, but your service provider will be able to determine if the location you have chosen will be adequate for proper operation. • Once an acceptable location for your Base Unit has been chosen, your service provider will complete the installation. IMPORTANT : If you choose to relocate your Base Unit, please contact your service provider prior to doing so. This will allow them to ensure continued operation of your system. Page 4 OPERATION of the WESROC ® RMS DELUXE BASE UNIT Operational Overview • The Base Unit has three pushbutton switches on the top: o The single button on the left-hand side is the MODE button. o The center button is the DOWN ▼ arrow. o The right-hand button is the UP ▲ arrow. • The MODE button toggles the display between Tank Level, Time, and Temperature displays. The UP/DOWN arrow buttons select which tank/transmitter is displayed. Power Up • When the Base Unit is first powered on, all of the display segments, icons, and LEDs will be illuminated for about two seconds. This is done to ensure all display components are working properly. The Base Unit will then return to the mode that was last selected prior to power loss. Tank Level Display • This mode is indicated by the illumination of a % symbol on the right side of the display. The number on the left is the tank transmitter number, and the number on the right is the tank level. If more than one tank is being monitored, the UP/DOWN arrow buttons may be used to scroll through the tank list. Your service provider has left you a notification on the back …
