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°F (0°C) to 25°F (13.75°C). Default is 5°F
(2.75°C) for both Deadband High and Deadband Low).
