1. Introduction

Energy is a large cost for hotels, and EMS (Energy Management System) is a way of achieving energy savings in guest rooms. With the Orion EMS software option to VISIONLINE it is possible to

view the Orion EMS status of different rooms modify the configurable parameters for a room (or group of rooms/ the entire property) provide alarm conditions provide energy savings reports provide preventative maintenance reports

Note: For mounting of Orion EMS devices, installation of the software option etc, see Installation manual Orion EMS.

A main task for Orion EMS is to determine whether or not a guest room is physically occupied. When a room is not occupied, Orion EMS controls the HVAC (Heating Ventilation and Air Conditioning) systems based on the configurable settings of the system. Note: In the rest of this document, the following applies unless something else is stated:

- the term 'thermostat' includes thermostat as well as thermostat controller

- the information is common for both Orion Thermostat-Zen-HV and

Orion Thermostat-Original-LV

Note: For information about what firmware to use in different Orion EMS configurations, see the document Upgrading an RFID lock for an Orion EMS offline scenario.

Note: The best conditions for Orion EMS are obtained if also the locks are online and commissioned to the same ZigBee network as the thermostat and the motion sensor.

Certain Orion EMS operations cause alarms; see chapter Energy management summary

and Alarm list for details. Occupancy status is included in all alarms. This allows the staff

to fix the problem that caused the alarm without bothering the guest.

1.1 Orion EMS devices

The devices used together with Orion EMS are:

digital thermostat (two variants: Orion Thermostat-Zen-HV and Orion Thermostat-Original-LV) Note: Depending on installation conditions, also a thermostat controller is used or not (only applicable for Orion Thermostat-Original-LV). If it is used, the thermostat controller is the master of the system while a battery operated thermostat transmits the guest settings to the thermostat controller for processing and decision making. motion sensor door monitoring device; lock, RF door switch Note: It is also possible to use a wired door switch without radio, but this manual mainly describes the RF door switch. For more information about wired door switches, see Installation manual Orion EMS. gateway (the same as is used for online doors; requires the Online option) Note: The gateway is not used in offline scenarios.

Figure 1: Orion EMS example configuration; the thermostat shown in the picture is of Orion Thermostat-Original-LV type.

The thermostat has a built-in ZigBee router via which it communicates to the software and the devices within the room. The thermostat stores all parameters needed for Orion EMS; if the thermostat controller is used as well, the parameters (with a few exceptions; see Installation manual Orion EMS for details) are instead stored in the thermostat controller. The parameters are either transferred online from the software or from the Orion Service software; see Quick reference guide Orion Service for more information about the latter.

Note: For each room number, it is possible to have either

one wired thermostat up to five motion sensors up to five door switches

OR

one thermostat controller up to five battery thermostats up to five motion sensors up to five door switches

1.2 Terminology

Deadband

The range the temperature is allowed to drift before the heat or air conditioner is turned on

Default setpoint

Default setpoint is the temperature which the thermostat is set

to until a guest changes the temperature. The thermostat will also return to the default setpoint after guest check-out.

Dynamic setback

The dynamic setback temperatures are configured as a set number of degrees above or below the guest setting. For example, if the guest setting is 68 ºF (20 ºC) and the unoccupied setback is configured to 7 ºF (4 ºC) above the guest setting, the system will allow the temperature to drift to 75 ºF (24 ºC) when the room is unoccupied.

EMS

Energy Management System

Exterior door timeout

The time that will pass before the HVAC is turned off after an exterior door is left open

FCU

Fan Coil Unit

Freeze guard

If the temperature in any room with a thermostat goes below 39 ºF (4 ºC), there will be an alarm and the HVAC will start heating.

HVAC

Heating Ventilation and Air Conditioning

Intelligent switch

The intelligent switch is an output for lighting control which works according to the occupancy status. The available alternatives for intelligent switch are

disabled; default use RV output

use G2 output If intelligent switch is applicable, normally 'Use RV output' should be marked unless the air handler is a heat pump. In the latter case, mark 'Use G2 output' instead.

Motion sensor

A device that detects a person's movement in an area

Occupied

Someone is physically in the room; see section Room occupied for more information

Occupied limits

Limits the Set temperature range, i.e. the temperature which the guest can set the thermostat to

PTAC (Package Terminal Air Conditioner)

A PTAC is a fully self contained system that is typically located on the exterior wall of a hotel room. These units come in standard control or heat pump models.

Pre-condition time

Number of hours the thermostat shall run at the default setpoint after check-in. If no entry has been done when this time expires, the unoccupied setback will be assumed. The pre- condition time can be 1-12 hours or 'disabled' (default is 2 hours).

9

DRAFT 66 8003 001-8

Pulse length

The welcome scene can be set up to have a pulse length:

0 = welcome scene always off

Chosen length in the interval 1-255 seconds

Refresh cycle

The Orion EMS system can, in setback control, run the A/C unit every 25 minutes for a period of 2 minutes to re-circulate the air in the room; the optional function is only for cooling mode.

Setback

The temperature the room is allowed to drift to when the room is unoccupied. Also see dynamic setback and static setback.

Setback override

The Orion EMS features can be overridden until the room is unsold again, or until a certain time. If desired, the time can be set far ahead so that the setback override is in practice until further notice.

Setpoint

The temperature which the guest has set on the thermostat.

Static setback

The static setback temperatures are configured in the system and do not change based on the guest settings. For example, if the unoccupied upper setback temperature is 79 ºF (26 ºC), the system will allow the temperature to drift to 79 ºF (26 ºC) when the room is unoccupied regardless of the thermostat setting (this example assumes that it is summertime) when the room becomes unoccupied. As soon as the guest returns to the room, the temperature is returned to the guest setting.

Unoccupied

No one is physically in the room although the room may be currently rented; see section Room unoccupied for more information.

Unsold

The room is not currently rented and no one is in the room. In this case, a deeper setback is implemented for greater energy savings. See section Room unsold for more information.

Welcome scene

If desired, it is possible to have a welcome scene which it is activated when the occupancy state for a room changes from unsold to unoccupied. The available alternatives for welcome scene are (default is 'disabled'):

disabled

use RV output

use G2 output

use solid state relay*

1.3 General about Orion Service

A service device and the software Orion Service are used for

initializing thermostats (setting room number and loading configurable parameters) commissioning the thermostat and the motion sensor in the network so the messages are routed correctly retrieving and displaying the event log from the thermostat upgrading module firmware in thermostat and motion sensor performing diagnostic operations, e.g.

- simulating inputs - e.g. door switch, motion/temperature

- reading out status of thermostat (the status of the motion sensor is

also shown)

- showing the output to the HVAC

- making a functionality test including fast clock mode; the thermostat

will raise the time one minute per second to test e.g. the room not occupied timer

See Quick reference guide Orion Service for more information about how the above operations are performed.

1.4 General about alarms

All Orion EMS alarms are shown in the dialog Energy management summary; see

chapter 3 for more information. In addition, they are shown in the alarm list. Unless

Orion EMS is installed as a separate client, the alarm list will also show other types of alarms not related to Orion EMS, e.g. housekeeping failed.

If the Communication option is set in the software, notifications about Orion EMS alarms can be sent via e-mail or SMS and reports can be sent by e-mail. The reports that can be sent concern e.g.

energy savings preventative maintenance schedules occupancy (the report shows the number of occupied rooms each night; a room is regarded as occupied for the night if it is physically occupied and there is at least four hours of occupancy between 8 PM and 6 AM) occupancy trend (the report is combined with the energy savings report and shows occupancy during each time of the day; it is also possible to make as an average for a longer period) battery warnings events for a selected room offline rooms

These reports are sent via e-mail at the selected period to users that have been set up in the user notification list of the software to receive the reports; see Installation instruction Communication option for further information.

DRAFT 66 8003 001-8

1.5 Events and commands

To the guest, the thermostat appears and operates as a standard digital thermostat; however, this device also receives entry and exit information from the door lock or switch as well as motion detected information from the motion sensor. This information is used to determine the occupancy status of the room and implement energy savings strategy based on this information.

In order for the locks to send door events to the thermostats, EMI events must be enabled. This is achieved by presenting an Enable EMI events card at each lock. The card is one of the ZigBee configuration cards that can be issued in VISIONLINE; see Installation manual Orion EMS for details. The following events are sent to the thermostat from the motion sensor:

motion detected battery status

If the lock is online, the following events are sent to the thermostat from the lock:

door open – staff card door open – guest card; includes check-out date/time, suite rooms and first time use door open from inside door closed deadbolt thrown/released

The thermostat stores the 75 latest events in a log. Note: In addition to the relevant events from the lock to the thermostat, additional events are sent from the lock to the hotel system.

There are also commands sent from the thermostat to the lock (if online) and the motion sensor:

to the lock: the optional auto-DND, which functions as privacy; no staff cards will be able to open the door (only guest cards and emergency cards will open) to the motion sensor: to turn off the motion sensor when the room is occupied and the door is closed, and to turn on the motion sensor again when the door is opened

Note: The commands from the thermostat to lock and motion sensor are not logged as events.

1.6 Basic EMS logic

The thermostat along with the motion sensor, lock and/or RF door switches, monitors the occupancy state of the room and operates based on this information. When the room is occupied, the guest is given control and can set the desired temperature. The thermostat will then heat or cool the room as necessary to meet the guest setting. When the room is not occupied, the thermostat will operate based on the configurable parameters of the system. The three occupancy states are occupied, unoccupied and unsold. The following events are considered as in-room events:

motion deadbolt engaged thermostat key pressed

1.6.1 Room occupied

When the room is occupied, control of the HVAC system is given to the guest. The guest sets the desired temperature and the HVAC system will control the room based on this setting.

The Orion thermostat will enter the occupied state only when the door is closed and in-room events are detected (motion, deadbolt engaged, thermostat key pressed). At this point, the guest has full control of the room temperature.

Note: 'Occupied limits' may be used to restrict the guest setting limits.

1.6.2 Room unoccupied

When the room is not occupied, the energy management logic takes control of the room based on the configurable parameters of the system. The system will set back the temperature to the unoccupied setting. The system has both an upper setback and a lower setback. The unoccupied setbacks may be static or dynamic; for unsold rooms, only a static setback is used. See section Terminology for more information about static and dynamic setback.

The thermostat will enter the unoccupied state upon the door opening or closing. If no in-room event such as motion is detected, the thermostat will remain in the unoccupied mode. The thermostat will continue to operate at the guest setting for the duration of the configurable 'Room not occupied' timer, at which point it maintains the room temperature based on the unoccupied setback temperatures.

14

DRAFT 66 8003 001-8

1.6.2.1 Door open in 'room unoccupied' mode

If the door is left open, the occupancy state will remain as unoccupied regardless of whether or not motion or another in-room event is detected. There is however also a run state in the thermostat which is based on the set-point/guest setting. The run state works differently depending on whether the open door is interior or exterior, see details below.

If the open door is configured as an interior door (i.e., opens to another air conditioned space), the thermostat will operate based on the guest setting as long as motion or another in-room event is detected. Each time an in-room event is detected, the ‘Room not occupied’ timer will restart. If the ‘Room not occupied’ timer elapses without motion or another in-room event being detected, the thermostat will maintain the room temperature based on the unoccupied setback temperatures.

If the open door is an exterior door (i.e., opens to a non-climate controlled space), the thermostat will turn off after the ‘Room not occupied’ timer expires regardless of whether or not motion is detected.

Note: If the exterior door timeout is set to ‘Short’, the thermostat will turn off the air handler after 20 seconds. See chapter 4 Thermostat profiles list, section Under the Timeout tab, for details about setting the exterior door timeout.

1.6.3 Room unsold

When the room is not rented, the setback is – to achieve more energy savings – deeper than when the room is rented but unoccupied. The system will enter the unsold setting when the room has been unoccupied for the duration of the configurable ’Room not sold’ timer. In the unsold mode, the temperature is based on the unsold setback temperatures.

Note: If using an online system, the room will immediately enter the unsold mode upon receiving a check-out command from the property management system (PMS) or at guest card expiration.

Note:The unsold mode gives the greatest potential for energy savings. For this reason, the online system allows for maximum energy savings as the room does not need to wait until the ‘Room not sold’ timer elapses to enter the deep setback mode.

1.6.3.1 Door open in 'room unsold' mode

Similar to the door open condition in the unoccupied state, the thermostat will control the temperature based on the guest setting when an interior door is open and motion (or any other in-room event) is detected for a period of time equal to the ‘Room not occupied’ timer. If the timer elapses with no further detection of in-room events, the thermostat will revert to maintaining the room temperature at the unsold setback.

If an exterior door is left open, the thermostat will turn the air handler off.

In order to maximize energy savings, certain considerations must be taken into account when staff members enter the room.

1.6.4.1 Door monitored by RF door switch

If the position of the door is monitored by an RF door switch, the staff member must leave the door open to avoid interrupting the ‘Room not sold’ timer. If the staff member allows the door to close, the room will enter the occupied state upon motion detection. As long as the door is left open, the ‘Room not sold’ timer will not be reset.

1.6.4.2 Door monitored by electronic lock

If the door position is monitored by the electronic lock and a staff key unlocks the door, the room will not enter the occupied state even if motion is detected while the door is closed. However, if a thermostat key is pressed or the deadbolt is engaged while the door is closed, the room will enter the occupied state. Note: If a staff member lets a guest into a room with the door position monitored by an electronic lock, the room will remain unoccupied until the deadbolt is engaged or a button on the thermostat is pressed.

1.6.5 Operating states

The following series of tables shows the operation of the system in various scenarios. Note: The scenarios consider that the unoccupied (or exterior door open) timers have expired if applicable.

1.6.6 Thermostat control chart

Figure 5

The thermostat control can be illustrated in a control chart, see example above.

If the temperature drifts above the setpoint or setback (depending on occupancy mode), the HVAC starts in cooling mode. The thermostat deadband is in this case 2 ºF, so when the temperature is within 2 ºF from the setpoint the HVAC is off (from 0 to 2 in the picture). If the temperature continues to rise, the thermostat output for ‘Fan 1/Low’ is triggered, then the output for ‘Fan 2/Medium’ and finally the output for ‘Fan 3/High’. If the temperature starts dropping, the HVAC then switches to heating mode. There is however a heat/cool switch deadband which in this example is 3 ºF, so the temperature is allowed to drift 3 ºF from the setpoint before the HVAC switches from cooling mode to heating mode. From 0 to -3 in the picture the HVAC is off; the output for ‘Fan 1/Low’ is therefore not triggered, since this would have been at -2. If the temperature continues to drop, first the output for ‘Fan 2/Medium’ is triggered and then the output for ‘Fan 3/High’.

The Orion EMS devices strive towards different temperatures depending on if the room is occupied, unoccupied or unsold.

For ‘occupied mode’ the goal is the setpoint, i.e. the temperature which the guest has set on the thermostat. For ‘unoccupied mode’ the temperature drifts to the unoccupied setback, which can be static or dynamic. For ‘unsold mode’ the temperature drifts to the unsold setback.
