Additionally, two of the W digital outputs are available for control program use. Also, the application engineer must consider the possible combinations of simultaneously energized outputs and calculate the VA ratings accordingly.

This value is used to control the adaptive recovery ramp rate during the HEAT recovery period. Check the Zone Manager mapping and referred points. The AOs can be set to be reverse acting.

Modulating heat with pneumatic valve actuator The higher the Integral Gain, the slower the control response. Ww7750a2005 the node is controlling a heat pump, HeatStagesOn indicates how many auxiliary heating stages are turned on. Wall Module Type 1. For honwywell wiring details, see the Prepare Wiring Diagrams section. As space temperature falls below the current Cooling Setpoint, the controller mode of operation is switched to the HEAT mode.

Smoke Emergency Initiation 1. Similarly, the cooling equipment is disabled if the outdoor air temperature falls below the OaTempClLkOut setpoint. Bypass status is a controller-timed event whose duration is set in BypTime. Off—no power to the processor. These recommended values are based on past experience with the applications and in most cases do not require further adjustment. Device WA Description controller and, honeywel, has a secondary voltage of At each power-up, the controller remains w770a2005 the Start-Up and Wait mode a random time from 0 to 20 minutes that is based on the units network number.


If the local sensor is configured by Select, OdHum is periodically sent on the network. If the resistor is located far away from the driven device, it is possible that noise will be added onto the 2-toV signal to ground line.

Additional features available in TA,B models include analog setpoint input knob, override honeyweell input pushbutton, humidity sensor TB modeloverride status LCD and digital display. Control Provided The W Controller is designed to w77502a005 a single air handler to maintain the units space temperature at the current setpoint. QA Excel 10 Zone Manager.

This source has the lowest priority status in the above mentioned schemes. If the analog input sensor is used, its measured value 0 to 5 inw 0 to 1. This mode can also be entered via a network command ManualOcc set to Unoccupied. These valves can be controlled directly from the space temperature like the staged control or, if the CascCtrl flag is set, they are modulated to maintain the discharge air temperature at its setpoint. When DlcShed is 1, demand limit control set by an energy management node is active.

When using different types is unavoidable, use a QA,B Router at the junction. All control functions associated with the failed NV are disabled as if the NV was not configured. This 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. Check the version numbers of the controller firmware, E-Vision and the E-Vision script.

When current-type sensors 4 to 20 mA are configured, the WB,C automatically switches a ohm resistor into the sensing circuit; so no external resistor is required. The smallest resolution is 0. WA construction in in. The three sources of manual override status are: One of the digital inputs is connected to a printed wiring board trace to let the embedded software know what kind of hardware is present.

Depressurize fan on, outdoor air damper closed. Skip to main content. Bits that are supported by the object are set to one. The time for each increment for this industry standard pulse time is 0. WC Controller with 4-to mA heating, cooling and economizer wiring diagram. If ProofAirFlow shows air flow, then the control continues to operate, but if ProofAirFlow fails to show air flow, then the control is again shut down for the minimum off time.

Local Dirty Filter Digital 2. WB,C wiring diagram with 4 to 20 mA enthalpy sensors and digital inputs.

Ideally, connect the earth ground to the ground bus at a motor control center or circuit breaker panel. Typical WA Controller with separate transformer application wiring diagram. This makes it possible for several occupancy sensors to be ORed together by binding them all to nviSensorOcc.

In addition the cycle rate specifies the minimum on and off time.
