■

The Rheem exclusive 7-Segment LED Display easily shows

system operating status codes and

diagnostic codes.

■

A Sealed Switch replaces the standard

contactor and

features optical

control and

latching mecha-

nism. The sealed

switch prevents

infiltration of

insects and dust. A minimal switching arc,

by the optical control, offers greater relia-

bility. The latching mechanism consumes

less power while reducing chatter.

■

The Status Indication and System Diagnostics feature ther-

mostat communication capability, built-in diagnostics, high

& low voltage monitoring and high & low pressure switch

monitoring. The thermostat communication capability alerts the

homeowner to any necessary service

requirements. Faster, more accurate

service is provided by the built-in

diagnostics, by providing the HVAC

professional with dependable informa-

tion. With the high and low voltage

monitoring feature, the control

provides alerts for out-of-range condi-

tions. In addition, high and low pressure-switch monitoring pre-

vents the system from operating outside of its normal parameters.

■

The fault recall feature will allow for the last six fault-codes

to be displayed, and will retain these codes even if power

failure occurs.

■

Built-in short-cycle protection allows the compressor to

restart easily without oil removal.

■

A 30-second minimum run-time for every compressor call

allows the oil to return to the compressor.

■

Active Protection monitors the system to prevent nuisance

lockouts and prevents compressor operation when poten-

tially harmful conditions are detected.

■

The compressor and fan are

controlled independently,

which reduces the starting load

and light dimming.

■

A manual push-button is

offered to operate the compres-

sor and fan for 5 seconds to

allow for an operation check.

■

In order to save time and

money, replacement automo-

tive fuses can be utilized instead of replacing the entire

control board.

TECH

™

COMPRESSOR

The 2-Stage Scroll UltraTech

™

compressor is the key to efficiency

for this Rheem model. It’s the latest in high-efficiency compressor

technology. The advanced scroll

compressor offers low noise

and vibration characteristics

and features tolerance to

liquid refrigerant and system

contamination. The Scroll

UltraTech
