APPLICATION

The Excel 12 Fan Coil Unit (FCU) + Light application supports three HVAC sequences (HEAT, COOL, or CHANGEOVER) with control limits, air-quality control, free inputs, free outputs, and up to three 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:

 Three 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.

 Up to two limits (any combination of temperature limits

and/or air-quality limits)

 Min./max. limits can be used to limit the sequence output

according to you requirements. The limits are valid only in the occupancy mode. The example below shows that a heating valve will be opened as soon as the source temperature drops below T

 The air-quality can be controlled by opening a damper in

dependence on the CO2 level. The CO2 ramp is defined by CO2 (entered using the plug-in).

Example:

 CO2  CO2  range of operation = 50%

The damper starts opening as soon as the level of 1000 ppm is reached. The maximum value (range of operation) is reached at position CO2

NOTE: The temperature limitation and the air-quality control

have priority over the temperature control.

 Relative or absolute temperature setting via wall module.

Light Application:

 Three 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

ONWORKS® wall module)

 Two times 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). An additional relay is required to switch the light ON/OFF.

Constant light control helps to save additional energy. Normally, fluorescent tubes lose about 15% of their illumination over their lifecycle. To compensate for this, rooms are therefore usually dimensioned 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 in order to reduce the light output of the window light. This functionality can be configured via the plug-in.

 Grouping of lights, e.g. switch three lights via a single

pushbutton.

 Soft ON/OFF switching for dimmable lamps.  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.

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:

 Unused inputs can be used for monitoring. This

application supports the following free inputs:

 one temperature input (NTC20k)  one percentage input (0..10 V or 2..10 V)  three binary inputs

 The input values are communicated via nvoXL12Status.

Free Binary Outputs Can Be Switched Via L

ONWORKS:

 Up to two unused digital outputs (triac or relay outputs)

may be switched via L

ONWORKS® (nviFreeOutput[0/1]).

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 scheduled 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.

3 EN0B-0470GE51 R0110

Page 4

EXCEL 12: FCU + LIGHT

 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:

 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.

The sequences and the outputs of the slave controller must be configured in the same way as the master (e.g. sequence 1: heat, actuator type: thermal).

The temperature limit functionality and the air-quality functionality shall not be used in the slave controller if there is an EnergyHoldOff binding from the slave to the master.

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.  Optional air-quality control in the occupancy mode.  Wireless control via ZAPP (see ZAPP System

Engineering, EN0B-0286GE51).

Increased Flexibility:

 Flexible room usage if a L

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

LONWORKS® Network Interface

The Excel 12 communicates within the LONWORKS® network at a rate of 78 kbs via an FTT-10A Free Topology Transceiver, which provides transformer isolation; the bus wiring is thus insensitive to polarity.

Devices so equipped can be wired in daisy chain, star, loop, or any combination thereof as long as the max. wire length requirements are met. The recommended configuration is a daisy chain with two termination modules. This layout allows for max. bus length and has the highest communication reliability, particularly when adding on to an existing bus. Refer also to http://www.echelon.com

Configuration and Binding

Configuration is performed using Honeywell's LNS™ plug-in, which can be started from CARE 4.0 or any LNS™ tool (e.g. LonMaker for Windows™). Likewise, binding is performed using CARE 4.0 or any LNS™ tool.

LONWORKS® Service Button and LED

All models feature a LONWORKS® service button (accessible from the outside on top of the module).

The service pin message is broadcast:

 whenever the L  after each reset due to power-up, software reset;  if a hardwired pushbutton for lighting is pushed for more

than 10 seconds.

See also Excel 12 Installation Instructions (EN1B-0201GE51) for more-detailed information.

All models feature a L missioning and troubleshooting. The service LED displays numerous different behaviors indicating various module states for use in troubleshooting (see also Excel 12 Installation Instructions).
