JOHNSON CONTROLS

FORM 145.05-NOM2 (807)

If Supply Air Temperature Control and Dew Point 
Control are selected, it will pick the higher of the two 
outputs to control the economizer water valve.

If Return Air Temperature Control and Dew Point 
Control are selected, it will pick the higher of the two 
outputs to control the economizer water valve.

If Supply Air Temperature Control, Return Air 
Temperature Control, and Dew Pont Control are 
selected; the Unit Control will compare the Supply 
Air Temperature Control output to the Return Air 
Temperature Control output and select the lower of 
the two outputs.  It will then compare it to the Dew 
Point Control output and select the higher of the two 
values.

The 0 to 10 volt analog output is located at the AO-1 
terminals 1 and 2 and is used to control the outdoor 
and return damper motor.  As long as the outdoor air 
economizer is enabled and the unit Air Flow Switch is 
closed, the output will never be less than the 

“O/A MIN 

POS”

 setting.

COOLING OPERATION

The following parameters must be programmed through 
the 

“Setpoints” 

section of the Keypad / Display or by 

a communicated input.

“AC-S/A TEMP EN”

 – The unit can control the 

operation of the cooling function by either the supply 
air temperature or the return air temperature.  If supply 
air control is desired, this value must be turned ON.  ON 
is the default value.

“AC / ECON S/A SP”

 – This is the set point the 

controller will control to if the unit is confi gured for 

“AC-S/A TEMP EN”

, the default value is 55.0° F.

“AC-R/A TEMP EN”

 - The unit can control the 

operation of the cooling function by either the supply 
air temperature or the return air temperature.  If return 
air control is desired, this value must be turned ON.  
OFF is the default value.

“AC / ECON R/A SP”

 – This is the set point the 

controller will control to if the unit is confi gured for 

“AC-R/A TEMP EN”

, the default value is 75.0° F.

Sequence of Operation

Supply Air Temperature Control

The cooling will be enabled when the supply air 
temperature is 5.0° F greater than the 

“AC / ECON S/A 

SP”

 set point.  Cooling will be disabled when the supply 

air temperature is 10.0° F less than the 

“AC / ECON 

S/A SP”

 set point.  The control waits fi ve minutes from 

the time the supply air temperature drops 10.0° F below 
the set point before it disables the cooling.

The control compares the supply air temperature to 
the 

“AC / ECON S/A SP”

 set point and generates a 

variable percentage output based on the difference and 
the amount of change in the supply air temperature to 
a change in output.  This output is used to modulate the 
chiller water coil valve actuator.

Return Air Temperature Control

When the unit is under Return Air Temperature 
Control, the cooling will be enabled when the return air 
temperature is 2.0° F greater than the 

“AC / ECON R/A 

SP”

 set point.  Cooling will be disabled when the return 

air temperature is 0.5° F less than the 

“AC / ECON R/A 

SP”

 set point.  The control waits fi ve minutes from the 

time the return air temperature drops 0.5° F below the 
set point before it disables the cooling.

The control compares the return air temperature to the 

“AC / ECON R/A SP”

 set point plus 1.0° F and generates 

a variable percentage output based on the difference and 
the amount of change in the return air temperature to a 
change in output.  This output is used to modulate the 
chiller water coil valve actuator.

Dew Point Temperature Control (FlesSys Units)

In addition to Supply Air Temperature Control and 
Return Air Temperature Control, Dew Point Temperature 
Control can also be selected on FlexSys units.  The Unit 
Control compares the derived Dew Point Control set 
point and the dew point of the supply air; and generates 
an analog output based on the difference and the amount 
of response to a given change in output.
