페이지 인쇄ODT Limit Potentiometer
A low cost Outdoor Air Sensor can be used to monitor
the outdoor temperature and if the outdoor temperature is
greater than the ODt Limit, multi stage heating is inhibited
if the option was selected.
In a dual fuel heat pump, the ODt Limit is used to
automatically switch the panel to the auxiliary heating
system.
FA Timer Potentiometer
When Damper4 is used as a fresh air damper, the
minutes of fresh air per hour can be set on the FA timer
potentiometer. the fresh air minutes will try to be fulfilled
during a heating or cooling call. If the fresh air minutes
cannot be fulfilled during a call, Damper4 will be opened
and the indoor fan will be activated.
Damper LEDs
Any of the four green damper LEDs will light when the
damper represented by that LED is in the open position.
A damper LED will blink if it detects a zone thermostat is
calling for both heating and cooling that may be caused by
a shorted wire.
System LEDs
the nine red LEDs indicate the status of the HVAC
system. Each LED will indicate by being lit continuously
or blinking.

ODT LIMIT
Fan LED
the Fan LED will be lit continuously when the panel
is in continuous indoor fan operation. the Fan LED
will blink when the system is in Purge mode.
Cool LED
the Cool LED will be lit continuously when the
panel is calling for first stage cooling. the Cool
LED will blink when the panel is calling for second
stage cooling.
Heat LED
the Heat LED will be lit continuously when the
panel is calling for first stage heating. the Heat
LED will blink when the panel is calling for second
stage heating.
Status LED
the Status LED blinks continuously when the
panel is powered and indicates the microprocessor
is operating properly. If the Status LED is on and
not blinking, the automatic contractor test is in
progress.
SA Limit LED
the SA Limit LED is on continuously when a
Supply Air Sensor is installed. the SA Limit LED
blinks when the panel is in supply air limit status
(Heating or Cooling temperature exceeded).
ODT Limit LED
the ODt Limit LED is on continuously when an
Outdoor Air Sensor is installed. the ODt Limit
LED blinks when the panel is inhibiting second
stage calls because of ODt Limit or the dual fuel
heat pump has switched to the auxiliary heating
system.
Capacity Limit LED
the Capacity Limit LED is on continuously when
the panel is in stand by mode for capacity limit.
the Capacity limit LED will flash when inhibiting
multi stage heating and cooling because half or less
of the zones are calling.
Emergency Heating LED
the Emergency Heating LED is on continuously
when the panel is in the emergency heat mode and
will blink during an emergency heat call.
Fresh Air Cycle LED
the FA Cycle LED is on continuously when the
fresh air damper mode is selected and blinks when
the damper is opened for fresh air.
