ENGINEERING DESIGN SPECIFICATIONS
Advanced units need advanced specifi cations. 
ClimateMaster’s new Engineering Design specifi cations 
provide the most detailed information for your next project. 
LITERATURE
At ClimateMaster, Innovation never sleeps. As new 
advances are made, and new products are released, the 
need for accurate literature becomes critical. Every piece 
of technical literature that ClimateMaster produces is 
printed in our state-of-the-art on-demand printing facility. 
What this means is that we print only the literature we 
need at the time we need it. This insures that only the 
most current and accurate data is in the fi eld. 
SHIPPING
When you need that critical service part or piece of 
literature for your next presentation, you may rest assured 
that ClimateMaster has a shipping option for you. 
Networked with a variety of carriers such as FedEx, Watkins, 
Estes, Central Freight, Dugan, and many others, we provide 
fast and reliable shipping to anywhere in the world. 
THE FUTURE OF CLIMATEMASTER
Our long history of innovation has paved the way for 
future endeavors with a solid platform of success. Growing 
markets in Europe and Asia demand a different way of 
not only manufacturing our products, but also successfully 
marketing them. New government regulations will phase 
out R-22 refrigerant at the beginning of 2010 paving 
the way for new R-410a, a much more environmentally 
friendly refrigerant. Additionally, new federally mandated 
effi ciency increases of 30% becomes effective in January 
of 2006. In looking ahead, we continually strive for better 
processes, better designs, and better innovations that will 
keep ClimateMaster as the Global Leader in Water-Source 
and Geothermal Heat Pumps. 
ADVANTAGE EXCLUSIVES
Being a leader in innovation, ClimateMaster brings 
industry fi rsts, as well as industry exclusives, to our family 
of products.
CONTROLS
ClimateMaster offers two levels of solid-state digital 
controls; the CXM and DXM control board.
CXM
Our standard CXM control 
board comes programmed 
with ClimateMaster’s Unit 
Performance Sentinel 
(UPS) which monitors unit 
performance and notifi es 
the owner of potential unit 
problems before a lockout 
occurs. Additionally, the CXM’s eight standard safeties 
protect the unit from damage.
• Anti-Short Cycle
• Low Voltage
• High Voltage
• High Refrigerant Pressure
• Low Refrigerant Pressure (Loss of Charge)
• Air Coil Freeze (Excluding GC Series)
• Water Coil Freeze
• Condensate Overfl ow
DXM
Our enhanced controls option, 
the DXM control board offers 
all of the advantages of the 
CXM board but adds the 
following additional features:
• Multi-Stage Operation
• Night Setback
• Emergency Override
• Reheat Control
• Boilerless Electric Heat
DDC
CONTROLS
Factory mounted LONWorks 
or Multi-ProtoCol (MPC) DDC 
controllers are an available option 
on all ClimateMaster products. 
These controllers give owners the 
ability to implement a variety of 
building automation systems such 
as BACnet, ModBus, and Johnson 
N2. Through a web enabled 
PC, individual units, unit zones, and entire building 
systems can be monitored and controlled with the click 
of a mouse. The systems provide unit status, set-point 
control, performance curves, and fault indications.
