GENERAL

Excel 12 controllers are LONMARK® certified devices, and can thus be used in all open L

Excel 12 supports the following LONMARK® objects:

 1 Node Object (LONMARK® object #0).  1 Space Comfort Controller Fan Coil Object (profile

#8501).

 2 Lamp Actuator Objects (profile #3040).  1 Occupancy Sensor Object (profile #1060).  1 Sunblind Actuator Object (object #4).

A variety of hardware models are available, with different power supplies.

Page 6 provides a detailed overview of the available models. Select the model fitting your particular needs. The application can be downloaded into the unit's flash

memory. Honeywell's LNS™ plug-in allows you to configure the

application to match your specific requirements (e.g. light switching or constant light control [depending upon the availability of daylight and/or the occupancy state]; sunblind up/down depending upon daylight, occupancy, and wind speed).

The Excel 12 controller is designed for maintained zones.

EXCEL 12 FCU + LIGHT + SUNBLIND

APPLICATION

The Excel 12 Fan Coil Unit (FCU) + Light + Sunblind application encompasses the entire room, including one fan coil unit, two lights, and one sunblind.

The application is delivered together with the plug-in and must be downloaded into the unit's flash memory during start-up. Regardless of the given Excel 12 model, the user has the option of choosing from among the many different available Excel 12 applications. The user can customize the application using Honeywell's LNS™ plug-in with CARE or any LNS™ tool (e.g. LonMaker for Windows™). Customizations can be saved / reloaded for easy configuration of multiple devices.

Application Overview

One Fan-Coil Unit:

 Two sequences configurable for HEAT, COOL, and

CHANGEOVER.

 Support of thermal actuators, floating actuators, PWM,

0...10 Vdc, and staged output via triac outputs or relay outputs.

 3-stage fan via triac outputs or relay outputs.  Binary inputs for condensation, occupancy sensor,

window contact, etc.

Two Lights:

 ON / OFF switching dependent on:

 Occupancy sensor.  Three effective occupancy modes (occupied / standby

/ unoccupied). Effective occupancy is determined on the basis of the occupancy sensor, the schedule, and override input (if any).

 Light level (determined on the basis of data received

via the L sensor).

 Manual switching (via hardwired switches or

 Dimming / constant light control for two lights with just one

sensor. Dimming / constant light control is performed via analog outputs (this requires an HFD [High-Frequency Device] for dimming with 1...10 Vdc input).

One Sunblind:

 Positioning dependent on:

 The effective occupancy mode (occupied / standby /

unoccupied) determined by occupancy sensor, the schedule, and override input (if any).

 Light level (determined on the basis of data received

via the L

 Manual command.  Building supervisor command.

 Safety position dependent on:

 Frost / rain from weather station or XL500, etc.  Wind speed (determined on the basis of data received

via the L

 Open windows (determined on the basis of data

received via the L hardwired sensor) inhibit moving of sunblind.

Occupancy Modes:

 Occupied mode: The Excel 12 operates according to the

"occupied" heating and cooling set-points.

 Bypass: After the bypass button of a hardwired wall

module has been pressed or when corresponding data is received via the L

ONWORKS® network, the Excel 12

operates temporarily according to the "occupied" heating and cooling set-points. When the bypass time has elapsed, the controller reverts to the previous mode. The bypass time can be configured via plug-in.

 Standby mode: The Excel 12 operates according to the

"standby" heating and cooling set-points.

 Unoccupied mode: The Excel 12 operates according to

the "unoccupied" heating and cooling set-points.

 Occupancy sensor: The occupancy sensor is used for

FCU, light, and sunblind control. Hardwired and L

ONWORKS® occupancy sensors are supported. The

occupancy sensor determines the effective occupancy mode during scheduled occupied periods. Depending upon the actual occupancy sensor state, the effective mode will be either "occupied" or "standby."

Wall Modules:

 L

ONWORKS® wall modules.

 Hardwired wall modules (e.g. T7460, T7560).  Wireless wall modules (e.g. W7070+T7270 or RT7070).

Master / Slave Functionality:

The master / slave functionality allows easy adaptation to changed room usage.

Benefits of Integrated Room Control

The Excel 12's light management functionality provides you with a number of significant advantages:

Considerable Reduction in Energy Consumption:

 25...75% savings on electrical energy consumption for

illumination.

 Decreased heat generated by electric lights or incoming

solar radiation (by closing sunblind), thus reducing cooling energy requirements.

 Decreased electrical energy consumption due to constant

light control (see section "Constant Light Control" on page

7).

 Sunlight can be used to heat the room (sunblind up) if the

room is unoccupied and to avoid unnecessary cooling demands (sunblind down), as needed.

Increased Convenience:

 Occupancy sensor switches the light ON/OFF

automatically.

 Constant light control always provides the correct lighting.  The sunblind is lowered if the current outdoor light level

exceeds a configurable limit and is raised if the current light outdoor level drops below the desired limit, or in case of strong winds.

 Usage styles (e.g. presentation, working, etc.) can be

configured in conjunction with the Web Office Console.

 Wireless control via ZAPP (see ZAPP System

Engineering, EN0B-0286GE51).

Increased Flexibility:

 Flexible room usage if a L

ONWORKS® wall module or

ZAPP (wireless remote control) is used.

Reduced Engineering Effort / Expenses:

 Just one LONWORKS® node (instead of three) is required

to cover HVAC, Light, and Sunblind.  reduced engineering and installation effort (e.g. wiring,

binding, commissioning, etc.)

 lower cost due to reduced number of LNS™ credits  lower hardware total loop costs

Interoperability

Device Configuration

The controller is configured using Honeywell's LNS™ plug-in. The plug-in can be started from CARE 4.0 or any LNS™ tool (e.g. LonMaker for Windows™).

LONMARK® Objects Network Variables

The Excel 12 supports the following LONMARK® objects:

 1 node object (see Fig. 8)  1 space comfort controller object (#8501 SCC – Fan Coil)

(see Fig. 6)

 2 lamp actuator objects (#3040) (see Fig. 9)  1 occupancy sensor object (#1060) (see Fig. 7)  1 sunblind / closed-loop actuator object (#4) (see Fig. 10).

Insofar as a generally agreed-upon LonMark® object is not yet available, sunblind control is achieved in a generic fashion.
