MENU LEVEL & OPTION DESCRIPTION
CONFIGURATION MENU
(Cont.)
Demand Offset This entry will reduce excessive ON/OFF cycling in AUTO
mode. When this entry is a non-zero value, the unit will not
turn on again until Valve Position In reaches the Start Level
value AND the Outlet Temperature goes below the Active
Setpoint – Demand Offset. In addition, the heater will fire at
the 29% Valve Position level or below for a period of one
minute.
When this entry is set to zero, the unit will turn on again as
soon as the Valve Position in reaches the Start Level value.
There will not be a one minute delay when firing at the 29%
Valve Position level.
Setting range is 0 to 25. (Default = 0)
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 = 0 for both Deadband High and Deadband Low)
