MENU LEVEL & OPTION DESCRIPTION
CONFIGURATION MENU (Cont.)
Deadband High
Deadband Low
Deadband High and Deadband Low settings create an
“Outlet Temperature” Zone in which no Valve Position
corrections will be attempted.
The Deadband ZONE is defined as operating with an
Outlet Temperature between Active Setpoint +
Deadband High and Active Setpoint – Deadband Low.
When the Outlet Temperature reaches Active Setpoint
and remains there for a period of 15 seconds, the unit
will go into a DEADBAND MODE at which point no Valve
Position corrections will be attempted while the Outlet
Temperature remains anywhere within the Deadband
ZONE. When the unit is in the DEADBAND MODE, the
°F or °C LED will flash on and off. When the Outlet
Temperature drifts out of the Deadband ZONE, the
DEADBAND MODE will be terminated and the PID
LOOP will again attempt Valve Position corrections.
Setting range is 0 to 25. (Default is 2 for both Deadband
High and Deadband Low)
