The Rc Series Console - Johnson Controls RC Series Engineering Manual

The RC Series Console

High Efficiency
RC Series is the highest efficiency units available. Large
oversized air coils, water to refrigerant heat exchangers and rotary
compressors provide extremely efficient operation. This efficiency
means the RC Series requires less loop than any product on the
market. This can mean significant savings on commercial projects.
Quiet Operation
All RC Series Console product is ARI 350 sound rated using third
party sound testing. Room Noise Criteria Curves (NC Curve)
may be calculated using data from the ARI 350 ratings giving the
engineer total flexibility in assuring a quiet environment.
Standard Features
• Slope and Flat top configurations
• Extended cabinet options
• Footprint matches "legacy" products for easy retrofits.
• Attractive rounded corners heavy gauge cabinet.
• Quiet rotary compressors in all models.
• 2-dimension refrigerant piping vibration loops to isolate
the compressor.
• All interior cabinet surfaces including the compressor
compartment are insulated with 1/2˝ [12.7mm] thick
• 1-1/2lb [681g] density, surface coated, acoustic type glass
fiber insulation.
Flexible Control Options
The standard CCM (compressor control module) is a more reliable
replacement for electro-mechanical control applications. It features
a small microprocessor board that handles the lockout function of
the unit. A second microprocessor handles the unit mounted dial
thermostat for maintaining accurate room temperature. Thermostat
options include unit mounted or remote thermostat.
The optional Versatec microprocessor control board provides
complete monitoring and control with optional fi eld monitoring fault,
status and I/O LED indication for easy servicing. The Versatec
features a robust microprocessor control that monitors LP, HP,
Condensate, fi eld selectable thermistor freeze sensing, while
providing a fl exible accessory relay and fault output scheme.
Thermostat options include unit mounted or remote thermostat.
The optional FX10 control provides unparalleled capability
in several areas including performance monitoring, zoning,
humidity, energy management, and service diagnosis, and then
communicates it all thru standard DDC protocols like N2, Lon and
BACnet (MS/TP @ 19,200 Baud rate).
The most unique feature is integrating the FX10 into the RC Series
as both the heat pump and DDC controller providing both a cost
advantage and features not typically found on WLHP controls.
This integration allows heat pump monitoring sensors, status and
service diagnosis faults to be communicated thru the DDC direct to
the building automation system (BAS), giving building supervisors
detailed and accurate information on every piece of equipment
without removing an access panel. Thermostat options include unit
mounted sensor or remote sensor or remote thermostat.
CCM
Optional user interface for diagnostics & commissioning of
FX controls.
Easy Maintenance and Service Advantages
• 2 removable compressor access panels
• Separate air handler and compressor section access panels
permit service testing without bypass.
• Easy access to low voltage connector for easy thermostat wiring
(remote & thermostat option).
• Quick attach wiring harnesses are used throughout for
fast servicing.
• High and low pressure refrigerant service ports.
• Internal slide out blowers.
Factory Quality
• All refrigerant brazing is performed in a nitrogen environment.
• Computer controlled deep vacuum and refrigerant
charging system.
• All joints are leak detected for maximum leak rate of less than
1/4 oz. per year.
• Computer bar code equipped assembly line insures all
components are correct.
• All units are computer run-tested with water to verify both
function and performance. n and performance.
