This limit is set in the Excel 10 Zone Manager database as an absolute maximum.

When using a spring range of 5 to 10 psi with 10 w77550a2005 as the closed position, do not use the 0 to 10 psi model of the MMC Transducer; use the 0 to 20 psi transducer as the recommended selection. The minimum pulse time represents the analog value of 0 percent and the maximum pulse length that represents an analog value of percent. The reported economizer position is synchronized whenever an endpoint is reached full e7750a2005 or full close.
W775a02005 addition, if modulating economizer control is desired, a discharge air temperature sensor must be physically connected to the Excel 10 W Controller. See Application Step 6. The PID control algorithm used to control staged cooling is anticipator-driven, and is similar to the algorithm used in the T commercial thermostat. Outdoor Enthalpy, Type B—when the outdoor enthalpy meets the H type B requirements, the outdoor air is suitable to augment cooling. Subnet 1 is on the Zone Manager side of the router; Subnet 2 is on the other side.
Type of Economizer 1. The reported temperatures includes the offset correction provided by Config.

When in the HEAT mode, all cooling outputs are driven closed or off, and the staged heating outputs are enabled for use. If ManOcc changes to another value the timer is stopped.
Any change to Hardware Config. The PID control algorithm used to control staged heating is anticipator-driven, and is similar to the algorithm used in the T commercial thermostat. Estimate the program complexity of the Zone Manager one of three levels.

The factory default configuration of the digital output points on the WB,C Models follow terminal names are from the WA: For more information on note 2, refer to Fig. If there is any question about wire compatibility, use Honeywell-approved cables see Step 5 Order Equipment section. If ManHeatCoolPos is less than 0 or greater thanthe motor is overdriven for a period longer than the motor time to ensure that it hnoeywell at the end of travel.
Prepare Wiring Diagrams section, for wiring details. Wall Module Type 1. The second uses the wall d7750a2005 pushbutton see Fig. Prepare Wiring Diagrams General Considerations The purpose of this step is to assist the application engineer in developing job drawings to meet job specifications.
Honeuwell indicates the current suitability of outdoor air for use in cooling used by the control process EconEnable is periodically calculated either from the sensor s specified by nciConfig.

Voltage inputs are not available in the WA controller. When the bypass state has been activated, the bypass timer is set to BypassTime.
Turn off more accessible mode. This page location is: The states have the following meaning: Order Equipment for details on the various models of Wall Modules. If the local sensor is configured by Select, OdHum is periodically sent on the network.
If the outdoor air is not suitable for cooling use, the economizer is set to its minimum position, and mechanical cooling is allowed to come on immediately. Relative Humidity Percentage Sensor Voltage 10 5. The newest alarm is reported in type and the oldest is reported in type. The network input has priority over the other nine economizer control selections. Contacts closed means poor IAQ is detected. Schematic diagram for a typical WB Unit.
When DlcShed is 0, demand limit control is inactive. For example, if a controller was configured with two stages of mechanical cooling and an economizer, the application should be viewed in Fig. If the types do not match, the download does not occur and the user-entered values in the Application Selection screens all revert back to default values.
The three sources of manual override status are: AOs must use terminals 16, 17 or The resistor converts a 4 to 20 mA signal into a 2-to10V signal.
Order Status and History. There is no time clock configured or bound to the node. The issue of line-loss is also important in the case of the output wiring connected to the Triac digital outputs. See Appendix Hondywell of Operation, for further control details.
