Overview
The normally-open contacts of a fi eld-installed smoke/fi re alarm detector may be
n/a wired to this input to shut the heat pump unit down during an emergency. Unit
operation is ceased 5 seconds after a contact closure is detected at the input.
For units with a loop pump option, the status output from a factory installed
current sensor used to monitor pump operation may be connected to this input to
provide pump status during unit operation. The unit is allowed to run only when the
sensor contacts are verifi ed as closed at the input after the pump has been indexed
n/a
to run. If there's no contact closure after the loop pump has been commanded on,
the unit is not allowed to run, and an alarm is generated after 15 seconds. If the
pump fails during normal unit operation the compressors are shutdown after 20
seconds and an alarm is generated.
Select this confi guration parameter if a Mixed Air Temperature sensor is connected
n/a
in IN-5.
The Input Expansion Module is used in this input when multiple options that
n/a require a binary input are required (up to 3 inputs). The combinations of these
options are limited only to the seven (7) sets of three listed below.
These seven (7) sets of binary input combinations may be used with an IEM
connected to this input. The three (3) ports are labled (A, B, C) and must be
connected correspondingly. In situations where not all three inputs are used, the
other inputs may be disabled in the software, or the board may be jumpered if the
option requires a closed contact to function properly.
A factory-installed thermistor mounted on the heat pump unit's blower housing
(air handler section) is connected to this input for all orders requiring the factory
installed DDC option. It is highly recommended that for applications requiring
a more accurate representation of the supply air temperature, a duct mounted
n/a
temperature probe be used instead to relocate the source of the discharge air
temperature just downstream of the supply air duct. If this recommendation is
followed the factory-installed thermistor may be disconnected from this input, and
replaced with the leads from the duct mounted sensor.

Signal Label Overview
Binary Output 1 is factory reserved for the fan command (G) and is wired to the
unit terminal block in the electrical box. The fan mode may be software confi gured
G either for "continuous" mode (fan is energized continuously during occupied and
night set back modes), or confi gured to run in "auto" mode (fan is energized only
during a call for heating or cooling). Continuous mode is the factory default setting.
Binary Output 2 is factory reserved for the reversing valve command (O) and is
wired to the valve via the unit terminal block in the electrical box. For heat pump
O units, the output is energized during a call for cooling, and remains de-energized
for heating. For straight cool units (cooling only) where no reversing valve is
installed, the output is disabled and not used.
Binary Output 3 is factory reserved for the compressor stage 1 command (Y1) and
is connected to the UPM I board's "Y" terminal ("Y1" for dual compressor units
using the UPM II board) via the unit terminal block in the electrical box. The Y1
output is off when zone setpoint is satisfi ed and within the temperature deadband
(between heating and cooling setpoints). As the zone temperature rises above
Y1
the cooling setpoint and demand exceeds 30%, Y1 is enabled and PID methods
are employed to ensure the zone temperature is maintained within 1°F of cooling
setpoint. As the zone temperature drops below the heating setpoint and demand
exceeds 30%, Y1 is enabled and PID methods are employed to ensure the zone
temperature is maintained within 1°F of heating setpoint.
Binary Output 4 is factory defaulted for the compressor stage 2 command (Y2) and
Y2
is connected to the second stage solenoid (Y2S) for 2-step, single compressors,
or to the "Y2" terminal for dual compressor units using the UPM II board, via the
unit terminal block in the electrical box. The Y2 output is off when zone setpoint
H
is satisfi ed and within the temperature deadband (between heating and cooling
setpoints). The Y2 output is energized after Y1 has been on for more than 7
minutes, and the heating/cooling demand exceeds 60%.

For 1 compressor 1 stage units, Binary Output 4 may be confi gured for one of the
