■
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 mechanism. The sealed
switch prevents
infiltration of
insects and dust. A minimal switching
arc, by the optical control, offers greater
reliability. The latching mechanism consumes 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 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 information. In addition,
high and low pressure-switch monitoring 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 potentially 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 compressor 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.
