Factory speed settings are in Bold
Air flow values are with dry coil and standard filter
For wet coil performance first calculate the face velocity of the air coil (Face Velocity [fpm] = Airflow [cfm] / Face Area [sq ft]).
Then for velocities of 200 fpm reduce the static capability by 0.03 in. wg, 300 fpm by 0.08 in. wg, 400 fpm by 0.12in. wg., and 500 fpm by 0.16 in. wg.
Highest setting is for auxiliary heat (W) and lowest setting is for constant blower (G). The “Y1” and “Y2” settings must be between the
“G” and “W” settings.
The gray wire is not factory wired to the motor and is tied to the wire harness. This wire can be field connected and can be used with 3HT/2CL
thermostats or IntelliZone2 to deliver the required air flow for the Y2 signal.

Factory settings are in Bold
High-Static option not available for 012, 018, 060, and 070
Air flow values are with dry coil and standard filter
For wet coil performance first calculate the face velocity of the air coil (Face Velocity [fpm] = Airflow [cfm] / Face Area [sq ft]).
Then for velocities of 200 fpm reduce the static capability by 0.03 in. wg, 300 fpm by 0.08 in. wg, 400 fpm by 0.12in. wg. and 500 fpm by
0.16 in. wg.

cfm = airflow, cubic feet/minute
EWT = entering water temperature, Fahrenheit

NOTE: Minimum/maximum limits are only for start-up conditions, and are meant
for bringing the space up to occupancy temperature. Units are not designed to
operate at the minimum/maximum conditions on a regular basis. The operating
limits are dependent upon three primary factors: 1) water temperature, 2) return
air temperature, and 3) ambient temperature. When any of the factors are at the
minimum or maximum levels, the other two factors must be at the normal level for
proper and reliable unit operation.

Notes to Performance Data Tables
The following notes apply to all performance data tables:
• Performance ratings are based on 80°F DB/67°F WB EAT for cooling and 70°F DB EAT for heating.
• Three flow rates are shown for each unit. The lowest flow rate shown is used for geothermal open loop/well water systems with a minimum
of 50°F EWT. The middle flow rate shown is the minimum geothermal closed loop flow rate. The highest flow rate shown is optimum for
geothermal closed loop systems and the suggested flow rate for boiler/tower applications.
• The hot water generator numbers are based on a flow rate of 0.4 gpm/ton of rated capacity with an EWT of 90°F.
• Entering water temperatures below 40°F assumes 15% antifreeze solution.
• For non-standard EAT conditions, apply the appropriate Correction Factor tables.
• Interpolation between EWT, gpm, and cfm data is permissible, extrapolation is not.
