The AmericaSeries WLC/WLH offers a contemporary
design, ductless type evaporator combining attractive
appearance in any decor and high efciency condition­ing for small to medium size commercial or residential
spaces. The WLC/WLH is equipped with unit mounted
infrared compatible controls which also supports 24V
remote wall thermostat operation. Optional hand held
remote is available.

Heat Pump models provide up to a nominal 24,000 Btuh
of cooling and heating. Electric heat options are available
for up to 5KW of supplemental heat.

This American-made evaporator offers ease of instal­lation, operation, and service. It can be matched with
EMI’s S1C/S1H 09-24 and S1C 30-36 Btuh Single-Zone
Condensing Units, the S2C side discharge Multi-Zone
Condensing Unit, or the T2C, T3C, and T4C top discharge
Multi-Zone Condensing Units.

P/N 240005842, Rev. A [05/08]

• Operational range set point temperature
adjustable between 55°F and 90°F in one-degree
increments.

• Infra red compatible control allows use of optional
IR hand held controller

notE: Unit mounted controls are fully functional
without the handheld remote.

• Operation modes include Heat, Cool, Dry, Fan and
Auto Change-over.

• Fan Operation – Auto/On. High or Low speed fan

• Fan Purge – Fan remains on for 60 seconds after

Heat/Cool call is dropped for improved efciency

(Auto mode only)

• Room air sampling: Selectable time intervals
ensures the fan will cycle on periodically, in Auto
Fan Mode.

Benefit: Helps to eliminate room temperature

stratication.

• Selectable Fahrenheit (°F) or Centigrade (°C)

temperature scale.

• Dry mode – Operates cooling and electric heat
simultaneously to remove humidity. Optional
electric heat must be selected.

• Anti-Short Cycle Compressor Protection.

• Minimum on time for heating and cooling.

Benet: Helps eliminate room temperature drop

and system short cycling.

• Freeze Protection – Prevents evaporator freeze up.

• Test operation – Allows ease of testing after

installation (all timers are eliminated).

• Non-volatile back-up memory

Benefit: Control settings are maintained for an

indenite period during a power outage. When power

is restored the equipment will resume operation after
a three-minute compressor time delay .

• 7-day programmable with copy feature.

• Filter change indicator: A timer feature that

indicates the lter should be changed according to

the selected time.

• Motorized supply louver with optional sweep or

six stationary settings.

• Modular design – reduces parts required for control

• Manually adjustable vertical discharge ns.

• Easy access to pipe chase area from cabinet bottom.

Benet: Allows piping connections and condensate

pump installation with the unit mounted on the wall.

• Easily removable end-cap for access to control area

for installation and service.

• Condensate drain pan constructed of galvanized steel

(G90U), with anti-corrosion coating.

• Modular snap-in, 7-day programmable control with
large backlit LCD display, a “Change lter” display

feature and selectable Fahrenheit (Fº), or Centigrade
(Cº) temperature scale.

• Operational range between 55ºF to 90ºF, adjustable

in one-degree increments.
