RSPL Room Sensor. Without LCD Display. Slide-Pot Set Point Adjustment. Local Override. . Key Features and Benefits All Room Sensors: Attractive, low profile enclosure in a neutral color complements any room. Precise 10K ohm thermistor with + 0.36F (0.2 C) standard accuracy and less than 0.18 F (0.01 C) drift over a ten year span - requires no maintenance or re-calibration. A hidden communication port allows a laptop computer to be connected to the HVAC Control System. Multiple RS room sensors can be daisy-chained to one controller for temperature averaging or high/low select control. (One RS Plus, RS Pro or RS Pro F with up to four RS Standards.) Mounts on a standard 2" by 4" electrical box for easy installation. RS Plus: Features a convenient local setpoint adjustment through an easy to use slide potentiometer. Occupancy override is simple using the momentary push button on the RS Plus with a bright LED for immediate indication of status. When the override button is pressed during an unoccupied mode, the zone reverts to an occupied setpoint for a predetermined period of time. RS Pro/RS Pro F: Large, easy-to-read LCD on the RS Pro displays zone temperature, outside air temperature, heating setpoint, cooling setpoint, and local override (after-hours occupancy) time. Occupancy override is easy using the "Manual On" momentary pushbutton on the RS Pro. A single push switches the zone to an Occupied mode for a preset period of time. Multiple pushes increases the override time, and the LCD displays precisely how long the zone will stay occupied. The occupied time per push and maximum override time are fully programmable in EIKON Zone setpoints can be easily changed on the RS Pro by pressing the "Warmer" or "Cooler" button. How much each push affects the setpoint and the maximum total adjustments are fully programmable in EIKON. Pressing the "Fan Speed" button on the RS Pro F incrementally adjusts the fan speed of the fan coil unit. The "Mode" button can be used to select among several zone operation modes as programmed in EIKON.. Automated Logic Corporation. Automated Logic Corporation. RSPL. UPC: 683194550140.
