PRODUCT DESCRIPTION

The AmericaSeries WLCA/WLHA is available as a (Dx) direct expansion straight cool and heat pump. It offers a contempo- rary design in a ductless type evaporator and combines attractive appearance with high efficiency conditioning for small to medium size commercial or residential spaces. The WLCA/WLHA is equipped with unit mounted infrared compatible controls which also sup- ports 24V remote wall thermostat operation. Optional hand held remote is available.

Heat Pump models provide up to 23,000 Btuh of cooling and 20,600 Btuh of heating. Electric heat options are available for up to 5 kW of supplemental heat.

This American-made evaporator offers ease of installation, operation, and service. It can be matched with EMI’s S1CA/S1HA 09-24 and S1CA 30-36 Btuh Single-Zone Condensing Units, the S2CA side discharge Dual-Zone Condensing Unit, or the T2CA, T3CA, and T4CA top discharge Multi-Zone Condensing Units.

All EMI air handlers are backed by Enviromaster International LLC and are tested and rated in accordance with ARI standards 210/240 and UL 1995.

CONTROLS and COMPONENTS

Note: If the control is configured for unit mount control do NOT connect a wall thermostat to the unit.

•Large LCD Backlit Display

•Single unit mounted control pack- age, configurable to either unit mount or remote wall thermostat operation, reducing model number or SKU’s required.

•Universal control can be used in cooling only, cooling with electric heat, heat pump, or heat pump with second stage electric heat applications.

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

CONTROLS and COMPONENTS

continued

•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 efficiency (Auto mode only)

•Room air sampling: Selectable time intervals ensure the fan will cycle on periodically, in Auto Fan Mode to help eliminate room temperature stratification.

•Selectable Fahrenheit (°F) or Cesius (°C) temperature scale.

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

•Anti-Short Cycle Compressor Pro- tection.

•Minimum on time for heating and cooling Helps eliminate room temper- ature drop and system short cycling.

•Freeze Protection – Prevents evapo- rator freeze up.

•Test operation – Allows ease of test- ing after installation (all timers are eliminated).

•Non-volatile back-up memory will maintain control settings for an indefinite 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 fea- ture indicates when the filter should be changed according to the selected time.

•Motorized supply louver with optional sweep or six stationary settings.
