2 What are RS Room Sensors? RS sensors are thermistor-based temperature sensors used with any control module that connects to the Rnet such as an LGR, ME-LGR, SE line, ME line, ZN line, or WebZone control module. The four types of RS sensors are RS Standard, RS Plus, RS Pro, and RS Pro-F. An Rnet can consist of any of the following combinations of devices wired in a daisy-chain or star configuration: 1 RS Plus, RS Pro, or RS Pro-F 1 4 RS Standards 1 4 RS Standards, and 1 RS Plus, RS Pro, or RS Pro-F Any of the above combinations, plus up to 2 BACview's, but no more than 6 devices total NOTES If you use two BACview's, one can be powered by the Rnet, but the other must be externally powered. ZN line control modules do not support BACview6 s. RS Room Sensors Rev. 9/7/ Automated Logic Corporation

5 RS Pro features 2.75 in. (6.9 cm) 4.75 in. (12.1 cm) Setscrew Local access port Display The display shows occupancy, zone temperature, and an alarm bell icon. Celsius values are to the nearest 0.5 degree; Fahrenheit values are to the nearest full degree. The display shows Occupied when the zone is occupied from a regular schedule or from a manual override. MANUAL ON button Press the MANUAL ON button one time to override the schedule and set the zone to occupied for the amount of time defined in the Each pulse field on the RS sensor microblock's Properties page in WebCTRL. Press the button again to incrementally increase the time. For example, if the Each pulse field is set at five minutes, press the button once for an occupancy of five minutes, twice for ten minutes, and so on. The maximum length of time you can override the schedule is defined in the Max Accum field on the Properties page. The display shows the duration of the override in minutes. If the override time exceeds 199 minutes, the display shows the time in hours. To cancel the override, hold the button down until 0 displays. Wait five seconds for the display to show the current zone temperature again. RS Room Sensors Rev. 9/7/ Automated Logic Corporation

6 WARMER and COOLER buttons To raise or lower the zone's setpoint: 1 Press WARMER or COOLER to display the current average setpoint (the average between the heating and cooling setpoints). 2 Press WARMER or COOLER again to raise or lower the setpoint. You can adjust the setpoint by no more than the amount defined in the Max Adjust field on the RS sensor microblock's Properties page in WebCTRL. NOTE Pressing WARMER or COOLER will override an unoccupied schedule and set the zone to occupied for the amount of time defined in the Each pulse field on the RS sensor microblock's Properties page in WebCTRL. INFO button Press the INFO button to cycle through: the zone temperature the outside air temperature, if enabled in the control program the override time, in minutes the heating setpoint the cooling setpoint Local access port See To communicate through the local access port (page 11).

7 RS Pro-F features 2.75 in. (6.9 cm) 4.75 in. (12.1 cm) Setscrew Local access port The RS Pro-F has all the features of the RS Pro (page 5) plus the additional functionality described for the following four buttons. NOTE Much of the RS Pro-F's functionality depends on the setup of the RS Zone Sensor with Fan Control microblock in EIKON for WebCTRL. See the system engineer for instructions on using these four buttons. MANUAL ON button The Timed Local Override section of the microblock dialog box determines if pressing the MANUAL ON button sets the zone to occupied for a set amount of time in the same manner as the RS Pro or sets the zone to continuously occupied. INFO button This button cycles through the same information as the RS Pro and up to 4 additional inputs defined in the Optional Inputs section of the microblock dialog box in EIKON for WebCTRL. MODE button The MODE button lets you cycle through up to 4 operational modes defined with custom programming in EIKON for WebCTRL. The sensor displays various information for each mode based on the setup in the Mode section of the microblock dialog box. FAN button Press the FAN button to select the controlled equipment's fan speed. A fan icon on the left side of the display indicates when the fan is on.
