Fields

Name Definition
DLC Setpoint Bump Upon receipt of a DLC_Shed signal over the LonWorks-Bus network, the current operating setpoint value is bumped up/down (for cool/heat modes) by this amount. Select a value from 0 through 10.
Override Type Specify the type of Bypass override functions that are available from the Wall Module's Override button. You can select one of the following options:
  • None
  • Normal
  • ByPassOnly

(no Continuous Unoccupied allowed from the button).
Override Priority Set the priority scheme for the Bypass override function. You can select one of the following options:
  • Last - Whichever was last to occur - either the button was pushed or the network signal arrived.
  • Net - The network signal always takes precedence over the push button.
  • This field is enabled if Override Type is Normal or Bypass Only.
Bypass Time Set the time period for a bypass override event. Value ranges from 0 through 1080 minutes. Enabled if Override Type is Normal or Bypass Only.
Max. DaTemp SetPoint Value ranges from 65 deg.F through 135 deg.F (18 deg.C through 57 deg.C). Enabled if you selected a discharge air temperature sensor. This setting is only used if Cascade Control is enabled.
Min. DaTemp Value ranges from 0 deg.F through 60 deg.F (-18 deg.C through 16 deg.C). Enabled if you selected a discharge air temperature sensor. This setting is used in Cascade Control, and as the Low Limit alarm threshold for discharge temp.
Setpoint Knob Type Select Relative (plus or minus up to 10 degrees from the current actual setpoint set on the Zone Options page), or Absolute_Middle (the Wall Module’s knob sets the midpoint between the heat and cool current actual setpoints).

You can select one of the following options:

  • Unused
  • Offset
