Honeywelll is a device, such as a passive infrared motion detector, that contains a dry contact see following NOTE closure to indicate whether or not people are present in the space. The WB,C Models are intended for more complex applications.

If there is any question about wire compatibility, use Honeywell-approved cables see Step 5 Order Equipment section. When honeyqell a doubly terminated LONWORKS Bus structure, use a continuous daisy- FTT networks are very flexible and convenient to install and maintain, but it is imperative to carefully plan the network layout and create and maintain accurate documentation.

Bits that are supported by the object are set to one. When activated, the controller remains in Bypass mode until: See Alarm and AlarmStatus for related subjects.

When CascadeControl is 1 TRUEthen the discharge air temperature is controlled by an additional control loop based on the error signal from the space temperature control loop. For example, if controlling a cooling valve with Cascade Control enabled and with the discharge temperature within honeyweol. If the digital input source is configured, it has highest priority and determines the Occupancy mode.

The user has the option to disable the minimum run timer DisMinClTimer for cooling. During all modes all digital and analog physical inputs are periodically read, the diagnostic output network variables can be polled, the input network variables are received, and the output network variables are sent periodically. When memory size is betweenandbytes, the application may be too large.

Third party 2 to 10V, 2 to 10 volts displayed. This limit is set in the Excel 10 Zone Manager database as an absolute maximum. This can happen if the space or discharge sensors or wiring are in noisy environments and the value reported to the controller is not stable such that it bounces.

When in the HEAT mode, all cooling outputs are driven closed or off, and the staged heating outputs are enabled for use. The hooneywell five alarm reports sent via nvoAlarm are reported via AlarmLog. Correctly selecting the FiftySixtyHz decreases honeysell noise picked up by analog switch wiring from the power mains.

W systems in commercial buildings typically incorporate a packaged air handler system that delivers a constant volume of air at preconditioned temperatures to the zone being served. Also, when a wall module setpoint pot is configured, this value serves as the lower limit on the user adjustable remote setpoint pot wall module.

The user has the option to disable the minimum run timer for heating DisMinHtTimer.

See Application Step 6. All actions, in this case, taken from the Override pushbutton are locked out. The node with Bypass bound normally does not have a wall module.

The output has the following states: SenOcc indicates the current state of the sensed occupancy and is calculated from nviSensorOcc and the local occupancy sensor via nvoIO. This, in effect, cancels a timed bypass or a continuous unoccupied mode. Occupancy Sensor Excel 10 W Controllers provide a digital input for connection to an occupancy sensor.


NONE disables the override button. The PWM actuator will begin to use the analog value at the end of the pulse and will continue to use this value until a new pulse is received. ManualMode remains unchanged until another mode has been commanded or an application restart has been performed.

DirtyFilter is set to 0 when a dirty filter has not been detected by either method for one minute. When the I x R loss of four volts is subtracted, only If an Excel 10 WA,B,C Controller or Zone Manager is not connected to a good earth ground, the controller internal transient protection circuitry is compromised and the function of protecting the controller from noise and power line spikes cannot be fulfilled.

Power wiring details for two or more Excel 10s per transformer. When HeatCoolMode is 1 and the node is controlling a heat pump, then cooling loads are controlled. Dependent on the configuration of the setpoint knob see Config. The controller can operate normally in this mode if the equipment and wiring match the default setupand given valid sensor inputs, the outputs are controlled appropriately to maintain space temperature at the default setpoint.

The Excel 10 W Controller expects a contact closure to indicate the space is Occupied. A power budget is simply the summing of the maximum power draw ratings in VA of all the devices to be controlled by an Excel 10 W Controller.
