APPLICATION

The Excel 12 FCU + 4 Lights application supports two HVAC sequences (HEAT, COOL, or CHANGEOVER), free inputs, 1 free binary output, and up to four lights.

The application is delivered together with the plug-in and must be downloaded into the Excel 12 controller's flash memory during start-up. 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

HVAC Application:

¾ Two sequences configurable for HEAT, COOL, and

CHANGEOVER

¾ Support of thermal actuators, floating actuators, PWM,

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

¾ 3-stage fan via triac outputs or relay outputs ¾ Binary inputs for condensation, occupancy sensor,

window contact, etc.

¾ Relative or absolute temperature setting via wall module.

Light Application:

¾ Four times ON / OFF switching dependent on:

• Occupancy

• Internal light level. The light will be switched ON if the

light level drops below the "dark level" and it will be switched OFF if it increases above the "bright level”. The "dark level" and the "bright level” can be configured via the plug-in.

NOTE: Do not select the “Auto Off Delay Timer” checkbox

insofar as this functionality is currently not supported.

• Manual switching (via hardwired switches or L

ONWORKS® wall module)

¾ Two times dimming / constant light control for two lights

with just one sensor. Dimming / constant light control is performed via analog outputs (this requires a HighFrequency Device for dimming with 1...10 Vdc input). An additional relay is required to switch the light ON/OFF.

Constant light control helps to save additional energy. Fluorescent tubes normally lose about 15% of their brightness over their lifecycle. To compensate for this, rooms are therefore usually equipped with 15% more illumination than actually necessary. With constant light control, the light level needs to be only 85% in order to achieve the required brightness. Further savings and comfort can be achieved if there is a constant light level in the room and the light is automatically dimmed when more outside light enters. The Excel 12 supports window correction to reduce the light output of the window light. This functionality can be configured via the plug-in.

¾ Grouping of lights, e.g. switch four lights via a single push

button.

¾ Soft ON/OFF switching for dimmable lamps. ¾ Light sensor: The light intensities typically encountered in

everyday life are listed in Table 1, while Table 2 presents the recommended light levels in various environments as set forth by DIN5035.

NOTE: One lux is equivalent to 0.0929 foot-candle.

Refer also to the plug-in help information for details.

storage rooms 50...200 washrooms, cloakrooms, corridors, etc. 100 office rooms (near windows) 300 office rooms (minimal outside light) 500 open-plan office rooms 750 schools (daytime) 300 night schools 500 gymnasiums 200 show rooms 300 commercial kitchens 500

NOTE: The intensity level depends on the sensor type and

the mounting location.

NOTE: The indoor light sensor must be suitable for sensing

artificial light, and should be mounted more towards the corridor.

Free Inputs for Monitoring:

¾ Unused inputs can be used for monitoring. This

application supports the following free inputs:

• one temperature input (NTC20k; nvoAiTemp)

• one percentage input (0..10 V or 2..10 V;

nvoAiValuePct)

• two binary inputs (nvoDiSwitch[0/1])

Free Binary Output Can Be Switched Via L

¾ One unused binary output (triac or relay outputs) may be

switched via LONWORKS® (nviFreeOutput).

Occupancy Modes:

¾ Occupied mode: The Excel 12 operates according to the

"occupied" heating and cooling set-points.

¾ Bypass: After the bypass button of a hardwired wall

module has been pressed or when corresponding data is received via the L operates temporarily according to the "occupied" heating and cooling set-points. When the bypass time has elapsed, the controller reverts to scheduled mode. The bypass time can be configured via plug-in.

¾ Standby mode: The Excel 12 operates according to the

"standby" heating and cooling set-points.

¾ Unoccupied mode: The Excel 12 operates according to

the "unoccupied" heating and cooling set-points.

EXCEL 12: FCU + 4 LIGHTS

¾ Occupancy sensor: The occupancy sensor is used for the

HVAC and light application. Hardwired and L

ONWORKS®

occupancy sensors are supported. The occupancy sensor determines the effective occupancy mode during scheduled occupied periods (time program with occupancy schedule runs on a different controller connected to the L

ONWORKS® network). Depending upon the actual

occupancy sensor state, the effective mode will be either "occupied" or "standby."

Wall Modules:

¾ LONWORKS® wall modules ¾ Hardwired wall modules (e.g. T7460, T7560) ¾ 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 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, thus reducing cooling energy requirements.

Increased Convenience:

• Occupancy sensor switches the light ON/OFF automatically.

• Constant light control always provides the correct lighting.

• 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 L

ONWORKS® node (instead of two) is required to

cover HVAC and Light. + reduced engineering and installation effort (e.g. wiring,

binding, commissioning, etc.)

+ reduced integration effort + lower cost due to reduced number of LNS™ credits + lower hardware total loop costs

INTEROPERABILITY

The Excel 12 has been certified as per LONMARK® Application Layer Guidelines V 3.3. and is thus interoperable with all other devices in open L party devices).
