1 An ONITY/UTC Business Partner SensorStat Wireless DDC The SensorStat is a state-of-the-art digital thermostat and occupancy sensing setback controller. Its intelligent technology manages the energy consumption of any guestroom HVAC system including: PTAC, Heat Pump, Split Systems, and Fan Coil Units. Since there is a computer chip in each unit, every guestroom actually has its own energy management system. The Wireless SensorStat (WDDC) uses several devices that work in conjunction to determine the occupancy status of a room. These devices are: a built-in passive infrared sensor (PIR), a flush-mounted door switch and transceiver and a Room Control Unit (RCU). When the door opens and closes, the door switch signals the SensorStat and RCU to search for occupants. The PIR senses both body heat and motion, so it only acknowledges people, not blowing curtains or ceiling fans in the room. Once a presence is detected, the SensorStat locks into Occupied Mode giving control of the thermostat to the guest, then directs the HVAC system to accurately adjust the temperature of the room to the guest's selected setting. When the occupant leaves the room, the door switch again triggers the PIR in the SensorStat to check for occupants. After it is determined that the room is unoccupied for a certain number of minutes (selectable), the SensorStat then goes into Unoccupied Mode and automatically sets the room temperature back to a comfortable, yet energy-saving level (setback). While in Unoccupied Mode, the PIR continuously searches for motion and if a presence is detected, the SensorStat immediately goes back into Occupied Mode. Setback temperatures are programmable and they never allow a room to become too cool or warm. This enables the HVAC to quickly recover to the guest's set temperature when the SensorStat is returned to Occupied Mode. 60 FROM FLOOR or Approved ADA Height PART NUMBER: BW DIMENSIONS: W 6.25 X H 4.75 X D 1.00 FCC ID: R32 RFM-100 / IC ID = 5058A RFM-100 BATTERY: THREE (3) AA 1.5 ALKALINE, INDUSTRIAL PLASTIC HOUSING: POLYCASE ZN-40 & CUT OUTS FOR SWITCHES & LED LEDS: 3 (DIAGNOSTIC) HEAT, COOL & MOTION JUMPERS: 2 (POWER & LED) DIP SWITCHES: 5 PROGRAM OPTIONS PROCESSOR: FREESCALE MPU (RAM & ROM) & 2 UARTS + SPI BUILT-IN PASSIVE INFRARED: 15 FT.

2 An ONITY/UTC Business Partner The Wireless SensorStat (WDDC) uses several devices that work in conjunction to determine the occupancy status of a room. These devices are: a built-in passive infrared sensor (PIR), a flush or surface mounted Magnetic Door Switch, Wireless Door Transceiver and a Room Control Unit (RCU). The RCU is the Command Center of the WDDC Energy Management System and is hard-wired directly to the guestroom HVAC unit. Its highly sophisticated logic and controls ensure accurate and appropriate actions dictated to the HVAC system according to the SensorStat s real-time energy management requests such as Heat/Cool decision, Fan Speed and Occupancy by RF 900 MHz Two-Way Communication. Room Control Unit (RCU-3) The RCU can be installed in ANY HVAC system. Its on-board memory will store all of the energy management parameters for the guestroom such as temperature setbacks, fan speeds, and property management settings. Once assigned to a particular guestroom HVAC unit, the RCU is bound to all components in the guestroom such as the SensorStat, Door Transceiver, Exterior Door Switch, Remote PIR, Mini-Bar, Door Lock, Lighting and Aux. Communications and forms a 900 Mhz mesh network. The RCU can then retrieve all data from every component in the guestroom and process it in real-time to determine the proper balance of guestroom comfort and energy savings.

3 An ONITY/UTC Business Partner Wireless Door Transceiver The Wireless SensorStat (WDDC) uses several devices that work in conjunction to determine the occupancy status of a room. These devices are: a built-in passive infrared sensor (PIR), a flush or surface mounted Magnetic Door Switch, Wireless Door Transceiver and a Room Control Unit (RCU). The wireless door transceiver can either be FLUSH or SURFACE mounted and both except the two conductor flush/surface mounted door switch, which is wire to a terminal block inside the Transceiver. The SURFACE/FLUSH mounted RF Transceiver is mounted on the door frame and accepts a wired door switch that is installed in close proximity (12 or less) to the RF Transceiver. This allows the SensorStat system to determine occupancy as follows: (Door Open + Door Closed + Motion = Occupied / Door Open + Door Closed + No Motion = Unoccupied). The SensorStat system also has the ability to control a exterior door/window, which is a simple enable or disabled feature. This option allows the SensorStat system to be turned off if exterior door/window is left open while HVAC is running for more than 20 seconds until closed. Another Transceiver control option allows the SensorStat system to determine if a room mini-bar was opened by reporting status via RF Wireless two-way communications from the RCU. The RF Transceiver can monitor up to four (4) interior door/windows, four (4) exterior door/windows and four (4) adjoining room doors for any type of guestroom application.

4 An ONITY/UTC Business Partner Magnetic Door Switches The Wireless SensorStat (WDDC) uses several devices that work in conjunction to determine the occupancy status of a room. These devices are: a built-in passive infrared sensor (PIR), a flush or surface mounted Magnetic Door Switch, Wireless Door Transceiver and a Room Control Unit (RCU). The Door Switch is used to monitor a guestroom entry door or window position as part of the SensorStat Energy Management System. The Door Switch contacts are wired to a low voltage input of the SensorStat DDC2F or to a Wireless Door Transceiver to provide the SensorStat and RCU door position status. When the SensorStat and RCU receive information of a change in position of entry door or window, (open or closed), it considers the event in combination with information from the PIR(s) to determine whether the room is occupied or unoccupied.

5 An ONITY/UTC Business Partner Passive Infrared Sensor (PIR) The Wireless SensorStat (WDDC) uses several devices that work in conjunction to determine the occupancy status of a room. These devices are: a built-in passive infrared sensor (PIR), a flush or surface mounted Magnetic Door Switch, Wireless Door Transceiver and a Room Control Unit (RCU). The wireless remote PIR is FLUSH mounted on adjoining rooms of the guestroom in order to accurately detect motion within the entire unit. The SensorStat system uses a combination of door contacts and state-of-the-art remote passive infrared (PIR) sensors with a unique tamper-resistant Flat lens, designed specifically for hotels and institutional applications, to sense the presence of people within the room. By knowing the occupancy status of any room dwelling, with HVAC control within the room, (Such as Hotel/Motel Guestrooms) the SensorStat will automatically reduce energy waste by setting back the temperature of the room to preselected temperature level (Unoccupied Set Point) when the room is unoccupied or unsold. With the addition of remote occupancy sensors, the SensorStat system can also be used in multiple room configurations such as Suites. This provides an enhanced level of digital HVAC comfort control while automatically reducing energy waste when rooms are unoccupied or unsold. 60 FROM FLOOR PART NUMBER: BW DIMENSIONS: 3.00 X H 4.75 X D 2.00 FCC ID: R32 RFM-100 / IC ID = 5058A RFM-100 BATTERY: THREE (3) AA 1.5 ALKALINE, INDUSTRIAL LEDS: 1 (DIAGNOSTIC) INFRARED DETECTION PATTERN: 15 FEET & 150 DEGREES JUMPERS: 5 (FOR ROOM DESIGNATIONS) LOCATION HEIGHT: 60 FROM FLOOR-MAXIMUM COVERAGE Recommended Location for BW In Master BR Facing Bed

7 An ONITY/UTC Business Partner Metal Oxide Varistor (MOV) The most common type of varistor is the Metal Oxide Varistor (MOV). It contains a ceramic mass of zinc oxide grains, in a matrix of other metal oxides (such as small amounts of bismuth, cobalt, manganese) sandwiched between two metal plates (the electrodes). The boundary between each grain and its neighbor forms a diode junction, which allows current to flow in only one direction. The mass of randomly oriented grains is electrically equivalent to a network of back-to-back diode pairs, each pair in parallel with many other pairs. When a small or moderate voltage is applied across the electrodes, only a tiny current flows, caused by reverse leakage through the diode junctions. When a large voltage is applied, the diode junction breaks down due to a combination of thermionic emission and electron tunneling, and a large current flows. The result of this behavior is a highly nonlinear current-voltage characteristic, in which the MOV has a high resistance at low voltages and a low resistance at high voltages. To protect communications lines (such as telephone lines) transient suppression devices such as 3 mil carbon blocks (IEEE C62.32), ultra-low capacitance varistors are used. A typical surge protector power strip is built using MOVs. In our SensorStat EMS system the MOV is installed on the 24v side of the Room Control Unit wiring to protect the RCU from spikes in voltage as shown in the illustration below.
