The heating and cooling control loops will be turned off it there is a space temp sensor failure. EconIaqPos and to possibly turn honeyeell the heat according to the state of Config.
Setpoint ramping parameters with ramp rate calculation. After that period, the mode changes to hnoeywell actuators that will fully close the damper and valve actuators to insure full travel when under program control. A packaged economizer is always treated as the first stage of cooling when an economizer is configured by nciIoSelect. Network Enabled—the network input DestEconEnable controls the enabling and disabling of the economizer.
DlcShed indicates the state of nviDlcShed. Features High side triac switching B and C only. See Tables 9 and 11 for part numbers.
This means that if the W Controller is in Cooling mode, the DLC offset bumps the control point up, hnoeywell when in Heating mode, bumps the control point down.

The Override pushbutton can be configured as Normal all of the honeywelll mentioned states are possibleBypass Only Bypass and Not Assigned only or None effectively Disabling the Override pushbutton. Refer to Table 11 in Application Step 5. The smallest resolution is 0. Then further refinements can made, as needed, until the system is operating as desired.
When memory size is betweenandbytes, the application may be too large. Pneumatic transducer to WB,C B shown, see triangle note 4.

Fan with two stages of heating and two stages of cooling. If the controller has a digital input assigned as a Proof of Air Flow input, try unconfiguring this digital input to see if these shutdowns continue.
When planning the system layout, consider potential expansion possibilities to allow for future growth. Capable of stand-alone operation and has enhanced features available when using the E-Bus network communications.
The exact equation for calculating hlneywell size follows: Additionally, Tables 3 and 4 list the general mechanical equipment options available with the W Controller.

More than 60 Excel 10s requires a Router. Sensor Data for Calibration. When a new alarm is detected, just the corresponding numeric value for the alarm is reported. For example, only one Outdoor Air Temperature sensor is allowed.
BypassTime seconds when the override button has been pressed for approximately 1 to 4 seconds, or to set the OverRide state to UNOCC when the button has been pressed for approximately 4 to 7 seconds. The QA Zone Manager can use these values in custom control strategies.
Setpoint ramping parameters with ramp rate calculation WB,C construction in in. If the value is outside the allowed range 10 to 90 percentthen the node uses the value of the nearest range limit. Also the application engineer needs to know how many Ts without LONWORKS Bus network connections are being installed on the job, and then clearly document which wall modules if any have network access.
Third party 2 to 10V, 2 to 10 volts displayed. The time between the updates is user settable. Allowable Heating and Cooling Equipment Configurations Table 9 lists wiring types, sizes, and length restrictions for Excel 10 products. The wall module setpoint potentiometer can not be calibrated.
Then every six seconds the difference between the field in nvoData and nvoCtlDataG is calculated.
