SA Controller Conﬁ guration Screens

Conﬁ guration Screen #34 - Broadcast VAV

Boxes Force to Fixed

SA Unit Cnfg ID 102

Broadcast VAV Boxes

Force To Fixed: NO

[0=NO 1=YES]

Enter <1> for YES to have all VAV/Zone controllers connected to this

SA Controller forced to their “Fixed Airﬂ ow” Position during the Morn-

ing Warm-up Mode of operation. Enter <0> for YES if you do not want

this to occur. See the VAV/Zone controller Setpoint Screens for setting

of the “Fixed Airﬂ ow” position. Default is NO.

Conﬁ guration Screen #35 - 1 HVAC Unit with

Boxes on Multiple Loops

SA Unit Cnfg ID 102

1 HVAC Unit w/ Boxes

On Multi. Loops: NO

[0=NO 1=YES]

Enter <1> for YES to have all broadcasts that have been conﬁ gured on

Conﬁ guration Screens 29 through 34 sent to all local loops on the entire

system, not just the local loop the SA Controller is on. This is normally

only required if you have a large HVAC unit that requires more than

the 58 VAV/Zone Controllers normally allowed on the local loop. This

allows other VAV/Zone Controllers connected on additional local loops

to receive the required broadcasts. This only is allowed when you have

a single SA Controller with VAV/Zone Controllers on multiple loops.

Other SA Controllers or add-on devices may be connected but no other

SA Controllers with VAV/Zone Controllers can be connected on the

system. Enter <0> for NO. Default is NO.

Both the Heating Stages and the DX Cooling Stages utilize Staging Up

and Down Delay Periods between stages and Minimum Run Times

and Off Times.

Both modes have their own set of Staging and Run Delay Times. The

Heating Timer Screens look exactly the same as the Cooling Timer

Screens except they reference the Heating settings instead of the Cool-

ing settings.

See the Sequence of Operation Manual for information on how these

Delays and Run Times are used.
