Remote Wall Thermostat Location
The thermostat should not be mounted where it may be affected by drafts,
discharge air from registers (hot or cold), or heat radiated from the sun
appliances, windows etc.. The thermostat should be located about 5 Ft.
above the fl oor in an area of average temperature, with good air circulation.
Mercury bulb type thermostats MUST be level to control temperature
accurately to the desired set-point. Electronic digital type thermostats
should be level for aesthetics.
Note: An improperly operating or poorly located remote wall thermostat
can be the source of perceived equipment problems. A careful check of the
thermostat’s location and wiring must be made then to ensure that it is not
the source of problems.
Desk Control
The unit’s electronic control has built-in provisions for connection to an
external switch to control power to the unit. The switch can be a central
desk control system or even a normally open door switch.
For desk control operation, connect one side of the switch to the D1
terminal and the other to the D2 terminal (See page 32). Whenever the
switch closes, the unit operation will stop.
Maximum Wire Length for Desk Control Switch
Auxiliary Fan Control
The electronic control also has the ability to control a 24 VAC relay to
activate an auxiliary, or transfer fan. The outputs are listed as F1 and F2 on
the interface connector (See page 32).
To connect the relay, simply wire one side of the relay to F1 and the other
side to F2. Anytime that the fan runs, the terminals will send a 24 VAC
signal to the relay. The relay must be 24 VAC, 50mA or less.
Note: The Desk Control, Auxiliary Fan relay and wires must be fi eld supplied.
Airflow Selection and Adjustment
Air flow direction adjustment
left or right side of the discharge opening. Each of the banks of louvers
can be directed left, right, up or down in order to achieve the most optimum
move it in the direction that you would like the air to be directed. Please
louvers than the other.
TO BRING IN FRESH AIR – Move the lever to the Fresh Air
position
which allows outside air to enter the room. This is useful in fall and spring as
a means of bringing in fresh outside air when using FAN ONLY . It can also
be used in the summer with the compressor in the Cooling Mode if you wish.
Fresh air and exhaust control
Your air conditioner has the ability to bring fresh air into the room or exhaust
stale air out of the room. The control slide is found on the upper part of
the unit (See Figure).
TO EXHAUST INDOOR AIR – Move the lever to the Exhaust
position. This will allow stale air to be expelled to the outside of the dwelling.
This is especially handy in the spring or fall when indoor air tends to get
stale, or after a social gathering involving smokers, or to remove cooking
odors.
BEST PERFORMANCE – Move the lever to the Re-Circulate Position
