SEQUENCE OF OPERATION
UNIT MOUNTED AND
REMOTE THERMOSTAT CONTROLS
RetroAire units can be equipped with unit mounted or
remote controlled thermostats. Turning the unit mounted
thermostat knob to the far left will produce the warmest
room temperature while turning it all the way to the right
will produce the coolest. These settings can be adjusted
for personal comfort.
CAUTION
!
Avoid rotating the thermostat knob back and forth
from heating to cooling. This causes the compressor to cycle on and off rapidly and WILL cause
damage to the compressor. Allow the compressor
to remain off for at least three minutes prior to
restarting the unit.
COOLING CYCLE
1. Place system switch in the “COOL” position.
2. Rotate thermostat knob (Figure A) clockwise until the
compressor fans start running and cold air begins to
flow from the unit. For a colder room temperature,
continue turning the thermostat knob
let the unit continue operating to cool the room and
remove humidity. If a warmer room temperature is
desired, rotate the thermostat knob counter-clockwise
until the compressor cycles off.
!
clockwise and
IMPORTANT: Room temperature must be below
85º F to energize the heater.
3. Place system switch in the “OFF” position. All operation should stop.
MOTORIZED FRESH AIR DAMPER
(Optional)
The optional motorized fresh air damper allows the operator
to move fresh air into the space to be conditioned. This is
done by placing the damper door switch in the
tion, opening the damper door and allowing fresh air to be
moved into the space. To stop the flow of fresh air, simply
place the switch in the “NO” position.
CHANGEOVER T-STATS
(Heat Pump Only)
On units with a changeover thermostat, the compressor
can run to an outdoor temperature of 40° F and then shut
off. Electric heat will then energize and assume the heat
ing demand until the temperature of the outdoor air rises
to approximately 50° F.
FAN CYCLE SWITCH
This option allows the operator of the
have the evaporator fan cycle or run continuously. With the
switch in the cycling position the evaporator fan will only run
when the unit is calling for heat or cooling. When the switch
is in the “CONSTANT” position, the evaporator fan will run
continuously unless the unit is physically turned off.

1. Place system switch in the “HEAT” position.
2. Rotate thermostat knob counter-clockwise until the
indoor fans start running and the electric coil starts
emitting heat. The condenser fans do not run during
the heating cycle unless the chassis is a heat pump.
After the unit starts running and the area gets warmer,
turn the thermostat knob clockwise until a slight click
is heard and the electric heater turns off. If a warmer
room temperature is desired, continue turning the knob
counter-clockwise and let the unit continue operating.
If a cooler room temperature is desired, rotate the
thermostat knob clockwise until the electric heater

The room temperature must be above
HEATING CYCLE - ELECTRIC
The Dual Motor PTAC has a drain connection at each end
of the condensate drain pan. This allows the condensate to
drain through the bulkhead to the area near the condenser
fan. The condenser fan has a slinger ring that picks up the
condensate and slings it on the hot condenser coil where it
evaporates. On heat pump models condensate can form on
the outdoor coil during the heat pump cycle. A temperature
sensitive valve in the base pan will allow condensate to flow
to an internal piping system or external drain kit (supplied
by others).
AQUASTAT CONNECTION
(Optional)
All straight cool Dual Motor PTACs are supplied with a
standard high volt aquastat connection. The connection
is located on the bottom or side with a black jumper wire
installed in molex. To wire option take jumper wire and cut
in half. Then connect 2 field supplied wires to the cut ends
of jumper and wire to aquastat (see wiring diagram for more
information). If option is not being used simply leave jumper
wire connected to unit.
