START-UP
Physical Inspection (pre power-up)
Check part # of iAIRE unit to ensure it is what was ordered.
Verify voltage/phases match.
1. Verify condition of unit and note any installation or shipping
damage to coils or cabinets.
2. Verify installation of condensate drain trap.
3. Verify power is available at disconnect and fuses are
installed if required. Check incoming power to make sure it
is within tolerance.
4. Verify that all airways are open. (Fire dampers and supply
air registers.)
5. Check blower belt tension. (if available)
6. Conrm that the space sensor is installed. (Space
Control units only, see wiring in gure “B” on installatoin
wiring diagram pages. Space Sensors must be wired using
shielded wire.
After power-up
1. Check incoming 3-phase power for a stinger leg if voltage is
208/230VAC. If so ensure that stinger leg (high voltage phase to
ground) is the center leg.
2. Go to iAIRE controller and set both the heat and cool CFM. The
heat CFM is the VFD % in the heat mode that the AHU fan will run.
The cool CFM is the VFD % the AHU fan will run in all other modes.
3. Remove panel from outside air section and verify outside air damper
is fully open. Set adjustment thumbwheel on damper motor for full
opening. Check crank arms and balljoints on damper mechanism
allow damper to open fully.
Charging
1. Locate Rawal device in condenser section. Locate the Rawal
Device and close the ball valve. This will stop ow to the Rawal Device
2. Disconnect 2-pin signal plug from Sporlan IB circuit board. This will
close the modulating hot gas valve to allow correct charging.
3. Invert refrigerant jug to provide liquid charge into suction line and
proceed to charge unit for 10 degrees of subcooling and 20 degrees
superheat. Depending on ambient conditions, evaporator leaving air
temperature should be between 48-58  F.
4. When charge is complete return signal connector to Sporlan IB
board and re-open Rawal ball valve.

5. Disconnect jumper from terminal strip input to allow the iAIRE
controller to take over machine.
6. Adjust sensor setpoint to a low setpoint to bring all cooling stages
on and check if hot gas line warms up.
TEST PROCEDURE
Verify operation as described above by monitoring liquid line
temperature and observing motor speed.
Heater check
1. Verify Kw of installed electric heaters.
2. Disconnect white space temperature sensor wire from
terminal strip. (This will make the iAIRE controller see a
space temperature of -40 degrees and start heaters) There is
a ve minute delay at start of heat cycle. With heater running
check amperage and verify discharge air temperature.
3. Return white space temperature sensor wire to terminal
strip.
Checking and adjusting system refrigerant charge.
Before connecting gauges to the systems suction and
discharge service ports, make the following adjustments.
1. Before running blower and compressors, close the manual
ball valve on the discharge of the #1 compressor Rawal valve
to eliminate Hot Gas Bypass during the charging process.
2. If Low Ambient is installed, shut o󰀨 ball valve to low
ambient and open bypass around low ambient to isolate L.A.
valve.
3. Before running blower and compressors, put iAIRE
controller in TEST mode and manually set Hot Gas Valve %
to 0.0% to direct all refrigerant to DX cooling.
a) Connect gauges. (Pre-load evacuated split systems
with nominal weight of refrigerant)
b) Enable FAN and then Cool Stage 1 in TEST mode and
allow several minutes for system to stabilize.
c) Note, high pressure saturation Temperature on
gauge and the temperature of the Liquid Line leaving the
condenser. (Condensing temperature should be 100-110
degrees minimum)
d) Calculate Sub cooling (Saturation Temp – Liquid line
Temp = Sub cooling)
e) Charge systems for 12-15 degrees of sub cooling. Add
refrigerant if sub cooling is low and remove if high. With all
cooling stages enabled system should deliver 55 degree air,
or less depending on ambient conditions.
f) Record sub cooling temperature __________ degrees
g) With controller still in TEST mode, increase the Hot
gas valve position in increments until discharge air, (DAT) is
raised to 70 - 72 degrees.

SPACE
In the UNOCCUPIED mode, the outside air unit will be
o󰀨 and the outside air damper, if supplied, will be closed.
Occupied or Unoccupied is signaled to the IAIRE controller
via a normally open or normally closed contact on the
OCCUPIED input with a clock or switch. An open contact
on the input indicates OCCUPIED, a closed contact
indicates UNOCCUPIED.
In the OCCUPIED mode, the outside air damper will
open and the supply fan will start. When equipped with
a Variable-Frequency Drive (VFD), the fan will ramp up
to the congured fan speed (dependent on whether the
unit is heating or cooling). ). The Fan input is monitored
to determine if fan is operating or not. If not operating, the
IAIRE controller will enter into an alarm state, start staging
o󰀨 compressors, and attempt to cycle the fan until it starts.
There is a congurable EAT Heat Lockout (default 58F).
If the EAT is < or = to this temperature, the electric heat
stages will cycle to maintain the room air temperature
setpoint.
There is a congurable EAT Cool Lockout (default 61F). If
the EAT is > or = to this temperature than Y1 is always on
and Y2-Y4 (if enabled) along with the modulated hot gas
valve will be used to maintain the room air temperature.
If the EAT is > the EAT Heat Lockout (default 58F) and <
the EAT Cool Lockout (default 61F) The modulated hot gas
valve is used to maintain room air temperature (Y1 will turn
on as necessary). While in this mode, if humidity is > 50%
then Y1 will stage on and if humidity is > 70% then Y2 will
stage on as well. Y2 will stage o󰀨, once on, if necessary to
help maintain room air temperature.
SEQUENCE OF OPERATIONS
DAT
In the UNOCCUPIED mode, the outside air unit will be
o󰀨 and the outside air damper, if supplied, will be closed.
Occupied or Unoccupied is signaled to the IAIRE controller
via a normally open or normally closed contact on the
OCCUPIED input with a clock or switch. An open contact
on the input indicates OCCUPIED, a closed contact
indicates UNOCCUPIED.
In the OCCUPIED mode, the outside air damper will open
and the supply fan will ramp up to the congured fan speed
(dependent on whether the unit is heating or cooling). The
Fan input is monitored to determine if fan is operating or
not. If not operating, the IAIRE controller will enter into an
alarm state, start staging o󰀨 compressors, and attempt to
cycle the fan until it starts.
There is a congurable EAT Heat Lockout (default 58F). If
the entering air temperature (EAT) is < or = to the lockout,
then the heat stages will cycle to maintain the discharge air
temperature DAT setpoint.
There is a congurable EAT Cool Lockout (default 61F). If
the EAT is > or = to this lockout than Y1 is always on and
Y2-Y4 is staged on depending on demand (if enabled),
along with the modulated hot gas valve will be used to
maintain the DAT.
If the EAT is > the EAT Heat Lockout (default 58F) and
< the EAT Cool Lockout (default 61F), Y1 will stage on
and the modulated hot gas will maintain DAT unless DAT
setpoint = EAT then free-cooling will engage and Y1 will be
o󰀨. While in this mode, if discharge humidity is > 50% then
Y1 will stage on and if its >70% then Y2 will stage on as
well.
SEQUENCE OF OPERATIONS NOTES
All forms of temperature control (SPACE / DAT / ultraDRY3) can come with the ability to control the supply fan with VAV
control.
VAV control can be set up for either duct static pressure control or building pressure control. In either of these cases,
there is a min CFM setting to maintain minimum airow to keep the evaporator coil from freezing and a max CFM setting
to make sure you cannot run more air than the unit can heat or cool.
Duct static control tries to maintain a user set constant pressure in the discharge duct of the equipment.
Building static control tries to maintain a user set constant pressure in the building space.

FAN SPEED CONTROL
These units are equipped with variable speed supply fan
control. There is a cooling and heating fan speed set
point. In this application, both the cooling and heating fan
speed set point should be the same. This should be set by
the test and balance contractor to provide and correct CFM
for the unit. Once the supply fan speed is initially set, it will
not modulate.
NORMAL HOURS (not night set back)
Cooling Mode(humidistat on cooling) –When the
temperature gets above the set point temperature by more
than 2 degrees, the compressor will come on and start
cooling the air. Once the temperature reaches the set-
point, the compressor will turn o󰀨 and the air will continue
to circulate in the space without heating or cooling.
Heating Mode (humidistat on heating) – When the
temperature gets below the set point temperature by
more than 2 degrees, the heat pump will come and begin
heating the air. Once the temperature reaches the set
point temperature, the heat pump will turn o󰀨 and the air
will continue to circulate in the space without heating or
cooling.
Humidity mode – When the unit is not running in cooling
or heating and the humidity sensor on the humidistat
registers a humidity higher than the set point humidity, the
compressor will come on for cooling and the hot gas on/o󰀨
valves will open to raise the discharge temperature of the
air entering the building after cooling. This will help reduce
the humidity without cooling the building o󰀨 too much.
Once the humidity is below the set point humidity, the unit
compressor and hot gas on/o󰀨 valves will shut o󰀨 and the
air will continue to circulate in the space without heating or
cooling.
NIGHT SET BACK HOURS
Allows the occupant to set a schedule across the 7 day, 24
hour week to schedule set back temperatures at night to
conserve energy.
UNOCCUPIED HOURS
Allows the occupant to set a schedule across the 7 day, 24
hour week to schedule the unit o󰀨 to conserve energy.
