Coil fluid temperature activation threshold and deadband
Path: Main > Setup > System # > System Config > Coil Fluid Options
The Coil Fluid Options help control the optional MultiCool coil or Economizer coil in equipped
Systems. Set the temperature threshold and deadband for using the MultiCool coil or the Economizer
coil. The System will compare the actual coolant temperature with the setpoint and deadband to
determine if the coolant is at a temperature low enough to operate the coils.
Coil Fluid Temp Activation: Threshold. Set the coil fluid activation threshold. The coolant
temperature must be below the threshold to use the optional MultiCool coil or Economizer coil.
Coil Fluid Temp Activation: Deadband. Set the MultiCool or Economizer activation deadband. The
deadband is the sensitivity range above the Coil Fluid Temp Activation: Threshold that the coolant
temperature can reach before the controller will stop using the MultiCool or Economizer coil. For
example, if the threshold is 10°C (50°F) and the deadband is 2.2°C (4°F), then the controller will
disengage the MultiCool coil or Economizer coil when the coolant temperature exceeds 12.2°C (54°F)
and will not reengage the coil until the coolant temperature reaches 10°C (50°F).
