Model Features

RASL- JEC Series

■

The Rheem exclusive Dual 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

reliability. The latching mechanism con-

sumes less power while reducing chatter.

■

The Status Indication and System Diagnostics feature

thermostat communication capability, built-in diagnostics,

current sensing and high & low pressure switch monitor-

ing. The thermostat communication capability alerts the

homeowner to any necessary ser-

vice requirements. Faster, more

accurate service is provided by the

built-in diagnostics, by providing

the HVAC professional with

dependable information. In addition,

high and low pressure-switch moni-

toring prevents 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 com-

pressor and fan for 5 seconds

to allow for an operation

check.

■

In order to save time and

money, replacement automotive fuses can be utilized

instead of replacing the entire control board.
