TRE Series Nomenclature - ClimaDry
®
II Option
Notes:
1. ClimaDry
®
II reheat option (Digit 12 - D, E, F or P) must be ordered with original equipment (cannot be field
added). Unit must have DXM2 control. 460 volts require 4 wire power supply with neutral. Not available for units
with internal water valve, flow regulator options, or 575Volt. Check unit submittal for limitations and specific
requirements.
2. All TRE rooftops with the ClimaDry
®
II reheat option require antifreeze to protect the reheat coil in low ambient
conditions. ASHRAE minimums for the region shall be considered during the calculation of the antifreeze solution.
3. ClimaDry
®
II is not recommended for applications with poor water quality (see water quality guidelines in unit
IOM). The copper heat exchanger (Digit 12 - D or E) with cast iron pump are designed for closed loop systems.
4. Max working water pressure for the ClimaDry
®
II option is 145psig.
5. Thermostat must be either:
A. Thermostat with dehumidification mode (ATP32U04 or similar)
B. Thermostat and separate humidistat or dehumidistat controller (see Table 2 for DXM2 DIP settings).
6. ClimaDry
®
II units must have minimum entering air temperature of 65°F DB / 55°F WB while in the
cooling, continuous fan, or dehumidification modes. Minimum entering air temperature while operating in the
heating mode (not continuous fan) is the minimum entering air temperature for the standard model (without the
ClimaDry
®
option) in the heating mode. Operating below these minimum entering air temperatures may result in
nuisance faults.
NOTE:
1. ALL UNITS COME STANDARD WITH DOUBLE ISOLATED COMPRESSOR,
STAINLESS STEEL DRAIN PAN, AND 75VA TRANSFORMER.
2. REFER TO BLOWER PERFORMANCE TABLES IN SPEC CATALOG
TO DETERMINE CORRECT DRIVE PACKAGE

6. HOT GAS BYPASS ON LEAD CIRCUIT ONLY.
HOT GAS BYPASS IS STANDARD WITH CLIMADRY
®
OPTION.
7. DIGIT 12 AIR COILS ARE REFRIGERANT & HYDRONIC AIR COILS.
