Description
Indicates the mode that the controller is operating in
with respect to the override switch. NIGHT indicates
that the switch has not been pressed and the
override timer is not active. DAY indicates that the
switch has been pressed and the override timer is
active. The controller then uses a day mode
temperature setpoint. This point is only in effect
when DAY.NGT indicates night mode.
Determines how the reheat modulation will be
sequenced while in heating mode. When HTG
LOOPOUT is above this value, then the reheat
modulates upward.
Determines how the reheat modulation will be
sequenced while in heating mode. When HTG
LOOPOUT is below this value, then the reheat
modulates downward.
Actual status of a contact connected to the
controller at DI 2. ON indicates that the contact is
closed; OFF indicates that the contact is open. If a
wall switch is used, it is connected to DI 2. See
WALL SWITCH.
Actual status of a contact connected to the
controller at Al 3/DI 3. ON indicates that the contact
is closed; OFF indicates that the contact is open.
When a contact is connected at DI 3, Al 3 is not
available. See AUX TEMP.
When flow rises above this value, the series fan will
turn ON.
This point is present, but not used in this
application.
When flow drops below this value and other
conditions have been met, the series fan will turn
OFF.
This point is present, but not used in this
application.
This point is present, but not used in this
application.
When flow drops below this value and other
conditions have been met, the parallel fan will turn
ON.
Indicates the mode in which the controller is
operating. Day temperature setpoints will be used in
day mode. Night temperature setpoints will be used
in night mode. This point is normally set by the field
panel.
This point is present, but not used in this
application.
