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)
