Setup and Adjustments

All P266 Series controls ship with factory-set default
values and mode settings. In most applications, the
default values and modes do not require field
adjustment.
If your P266 Series control application requires you to
change the value or mode settings, you must:
1. Calculate the new values and determine the new
mode settings required for your application. (See
P266 Series Control Values and Modes.)
2. Change the existing settings on the control to the
new values and modes using the P266 Series
control setup interface. (See Setting Values and
Modes.)
P266 Series Control Setup Interface
The P266 Series control setup interface consists of a
DIP switch block with eight binary switches, a push
button switch, and a green Light-Emitting Diode (LED)
(Figure 2). You can change the factory-set default
values and modes by repositioning the DIP switches
and saving the new settings. The number of LED
flashes (in sequence) indicates which value and/or
modes that you are saving. See Table 2 for more
information about LED flash sequences, values, and
modes.

During normal operation, the green LED is on. When
you press and hold the push button, the LED goes off
for 3 seconds then flashes two times. The LED then
goes off again for 3 seconds and flashes three times,
and continues in this pattern until seven flashes or until
you release the push button.
Each sequence of flashes indicates a value or a value
and set of mode settings. Releasing the push button
after the desired flash sequence saves the value
and/or modes that are currently set on the DIP switch
block. See Table 2 for more information.
After you complete the setup, set all of the DIP
switches to the ON position to lock out the push button
operation.
P266 Series Control Values and Modes
P266 Series controls have up to ten values and modes
(in six flash sequences) that can be changed in the
field. See Table 2 for more information about flash
sequences and the associated values and modes.
Start Voltage Value
The start voltage (VAC) is the voltage delivered by the
P266 Series control to the fan motor to run the motor at
minimum speed in your application.
The Start Voltage value is a percentage of the P266
Series control's input voltage. Use the following
formula to calculate the Start Voltage value for your
application.
