  • The Energy Patrol System™ decreases wasteful HVAC consumption 35% to 45%, while accelerating guest service and staff efficiency. In the lodging industry, heating and cooling guestrooms is the largest expense, therefore, it is not necessary to pay for utilities not
    required by guests.

  • The Energy Patrol System™ determines the physical presence of guests by detecting infrared body heat, therefore, it can’t be fooled by movement of drapes or ceiling fans. Guests have complete control of the rooms temperature while in the room. Guest can select
    heat or cool and set the temperature utilizing the existing HVAC unit and thermostat.

  • When guests leave the room for a specified period, Energy Patrol takes control from the normal thermostat and resets the room temperature to energy conserving levels preselected by hotel management. Energy consumption and costs are reduced 35% to 45%
    without adverse effects on guest comfort and convenience.

  • Demonstrates environmental responsibility and helps qualify for “green lodging” status and for rebates in certain areas

  • Up to four (4) levels of programmable Temperature Setback, adjustable in 1°F increments, with programmable time delays between levels

  • The Energy Patrol System™ connects to and reduces consumption on all hotel HVAC systems, including PTAC Units, Heat Pumps, Split Systems, and Fan Coil Units of any voltage.

  • The Energy Patrol System™ is designed to be TRANSPARENT to guests and easy to understand, maintain, and operate by non-technical personnel. In existing hotels our technicians have installed 15-20 rooms in one day. All wiring (a small, 4-pair phone cable) is hidden and room décor is not disturbed.


  • The OCCUPANCY IDENTIFIER (OI) feature allows staff members to know if the room is unoccupied from the hallway, eliminating guest disturbances and improving staff efficiency.

  • The REMOTE OCCUPANCY IDENTIFIER (ROI) extends the above OI feature to a map-like panel at the front desk, housekeeping office, security, or fire control station to provide instantaneous, real-time information on which rooms are physically occupied. ROI requires and utilizes one spare pair of telephone wires from each room to the telephone equipment room for easy installation.

  • When guests leave the room for a specified period, Energy Patrol takes control from the normal thermostat and resets the room temperature to energy conserving levels preselected by hotel management. Energy consumption and costs are reduced 35% to 45%
    without adverse effects on guest comfort and convenience.

  • Patrol Stat is a digital hotel thermostat that is easy to use. It allows guests to see the actual room temperature, which reduces the need for guests to set the thermostat to extreme temperatures, thus reducing energy consumption. Patrol Stat is available for PTACs, split systems, and heat pumps.

  • Up to four (4) levels of programmable Temperature Setback, adjustable in 1°F increments, with programmable time delays between levels

  • The Patrol Stat Plus is a Digital Fan Coil Thermostat that contains programmable energy management features and directly replaces existing mechanical Fan Coil thermostats of any voltage from 24-277 volts.

  • Patrol Stat and Patrol Stat Plus can stand alone or connect directly to the Energy Patrol System™ for maximum energy savings and guest comfort.

  • Patrol Luminations can be installed as a stand-alone occupancy sensing system to automatically turn off lights in public restrooms, conference rooms, linen closets, offices, and other areas in a hotel or commercial building when unoccupied. Auxiliary Sensors are
    available for “L” shaped rooms or areas with partitions. Patrol Luminations has multiple relay outputs and can connect to a Building Management or Security System for additional monitoring of occupancy. Patrol Luminations has an extended LIGHTS OFF TIME DELAY
    range of 30 seconds to 54 minutes.

In addition, Patrol Luminations can be connected to the Energy Patrol System™ HVAC control in guestrooms, offices conference rooms or other areas to automatically reset area temperature and turn off lights on a different time delay when the room has been unoccupied for the selected time. The Patrol Luminations circuit can be hidden in a closet out of view; only one Sensor is visible in the room. The combination of Energy Patrol System™ and Patrol Luminations will automatically reduce both HVAC and lighting expense without any intervention by occupants or staff. It will save more energy than typical CARD KEY energy management systems and is the ultimate energy management combination.



  • The guest arrives at the room.

  • The guestroom door is opened. The Energy Patrol System™ infrared Sensor is in the SENSING mode at this point.

  • The guest enters the room and is detected by the Sensor.

  • The Energy Patrol System™ releases HVAC unit control (air conditioner/heater) to its own thermostat.

  • HVAC immediately turns on if previously left on; if not left on, guest must turn on unit.

  • The Energy Patrol System™ remains in SENSING mode until door is closed. Guest must be detected at least once every five minutes to maintain HVAC operation until the door is closed.

  • After door is closed, and guest detection occurs, Energy Patrol System™ locks in OCCUPIED mode within fifteen seconds. No further detection of guest is required to continue HVAC operation. Energy Patrol System™ has released HVAC unit and has no control of guestroom environment. The guest has complete control of room temperature while in the room.

  • The room door is opened again. Energy Patrol System™ is reset from OCCUPIED to SENSING mode.

  • If another person has entered, Energy Patrol System™ will again lock in OCCUPIED mode after the room door is closed, with no interruption of HVAC operation, providing guest detection reoccurs within five minutes.

  • However, if all guests have left the room for at least five minutes, Energy Patrol System™ turns off HVAC unit thermostat. Energy Patrol System™ controls room temperature ONLY while guests are out.

  • The Energy Patrol System™ maintains room temperature at a comfortable, energy conserving, management selected, high or low setpoint while guests are out.



The Energy Patrol System™ consists of four basic components: the Patrol 7000 Sensor/Controller, Door Switch, HVAC Relay Assembly, and Transformer. (SEE FIGURE 1) Additional System accessories described elsewhere include the hardwired Patrol 7001 Slave Sensor, a Wireless Slave Sensor and Wireless Receiver.

1. Patrol 7000 SENSOR / CONTROLLER

The Patrol 7000 Sensor/Controller consists of a proprietary surface mount technology passive infrared (PIR) Sensor Module and advanced logic Controller circuits mounted on a small circuit board and contained in an aesthetically pleasing plastic enclosure.

  • The Patrol 7000 Sensor circuitry evaluates whether the guestroom is occupied or unoccupied by detecting changes in infrared (heat) energy due to the absence or presence of guests. It is not a motion sensor, but rather a MOVING HEAT SOURCE sensor; therefore, it is not affected by moving inanimate objects or stationary heat sources.

  • The Patrol 7000 Controller circuitry performs the various timing, delay, and control functions required by the system. The circuitry contains an adjustable internal Dual Secondary Thermostat Setback feature which allows the HVAC unit to maintain the room at a management selected, energy conserving temperature when the room is unoccupied or unrented.

    The Controller circuitry also sends low voltage signals to the HVAC Relay Assembly which controls the high voltage power source for the HVAC unit or the low voltage wallmounted thermostat.


The Door Switch is recessed mounted into the entry door frame and is connected to the Patrol 7000 to detect the opening and closing of the guestroom door. The electrical contacts are open when the door is opened and closed when the door is closed.

  • When the door is open, the Patrol 7000 assumes the SENSING mode to determine if the room is occupied. Upon detection of the guest, the Patrol 7000 releases the HVAC Relay to allow the HVAC unit to operate according to its own thermostat and controls. (Note: If desired, the Patrol 7000 has a circuit board selectable option to not allow sensing with the guestroom door open to prevent the HVAC unit from operating while the door is open.)

  • If guests are detected after the door is closed, the Patrol 7000 assumes the OCCUPIED mode, requiring no further detection of uests in order to continue normal HVAC operation.
    If the room is vacant and no guests are detected after closing the door, HVAC operation is disallowed after an adjustable time-delay and the Patrol 7000 remains in the SENSING mode indefinitely.

  • When guests are detected in the SENSING mode when first entering the room, or in the OCCUPIED mode after the door is closed, all control is released to the guest and the HVAC’s own thermostat.

  • When the door is again opened, after the System has been in the OCCUPIED mode, the Patrol 7000 returns to the SENSING mode to determine if another person has entered or if all persons have left the room. If the room is vacated for a preselected time period (5,
    10, or 15 minutes), control of room temperature is removed from the normal HVAC thermostat.
    (Note: The internal Dual Secondary Thermostat Setback Feature removes control of room temperature from the HVAC thermostat and enters a normal, rented room setback. The room will now be maintained at a management selected, energy conserving temperature
    (provided that the guest left the HVAC on.) Control is removed from the normal HVAC thermostat only after all guests have left the room and is immediately released to the guest upon their return.) If a communication link is installed or already exists between the Front Desk and the guestroom, the Patrol System can enter a deeper vacant, unrented room temperature setting for additional energy savings upon checkout of the guest, if this feature is selected.


The HVAC Relay Assembly is connected to the guestroom HVAC unit and receives signals from the Patrol 7000. When the enclosed low voltage relay is activated by the Patrol 7000, it removes high voltage power from the HVAC unit or its thermostat, thus deactivating the unit.
In the event of System failure, the HVAC unit will operate manually in a FAIL-SAFE mode, through the HVAC Relay’s normally closed contacts. The HVAC unit will also operate normally when disconnected from the Patrol System and in the maintenance shop for service.

The low voltage Transformer provides safe low voltage 24 vac power to operate the Patrol System Passive Infrared Guestroom Energy Management System.
