Product Overview

P266 Series Single-Phase Condenser Fan Speed Control Product Bulletin4
Auxiliary Fan Overlap determines the pressure range
overlap (as a percentage of the total pressure range)
between the fan stages set up on the P266 Series
control. The fan overlap value is equal for all auxiliary
fan stages set up on the control.
Increasing the Auxiliary Fan Overlap value decreases
the (On/Off) cycling rate of the auxiliary fans and
increases the pressure differential between auxiliary
fan stages (which increases the pressure range of each
auxiliary fan stage).
Test Voltage Mode
Test Voltage mode is a special setup, testing, and
tuning feature that allows you to wire a P266 Series
control and fan motor in the field, and test operate the
fan motor at different start voltage values without
connecting a pressure transducer. You can also set up
and test low-speed capacitor operation in the Test
Voltage mode. When your fan motor is operating as
desired, you can save the test settings, connect the
transducer, and operate your application at the saved
settings.
Ordering Information
The four basic types of P266 Series controls are based
on the supply voltage rating and whether the control
has an onboard, low-voltage power supply transformer.
P266A type controls are 208 to 240 VAC range
controls without onboard, low-voltage transformers.
P266B type controls are 460 to 575 VAC range
controls without onboard, low-voltage transformers.
P266C type controls are 380 to 460 VAC controls
without onboard, low-voltage transformers.
P266E type controls are 208 to 240 VAC range controls
with an onboard, low-voltage transformers.
Table 2 provides product code numbers, descriptions,
and details for the currently available P266 Series Fan
Speed Control models.
Table 3 provides product code numbers and
descriptions for the currently available P266 Series
Electronic Pressure Transducers.
Repair Information
If a P266 Series Single-Phase Condenser Fan Speed
Control fails to operate within its specifications, replace
the unit. For a replacement P266 Series control,
contact the nearest Johnson Controls representative.
