Product Overview

P266 Series Single-Phase Condenser Fan Speed Control Product Bulletin6
P266 Series Electronic Pressure Transducers
P266 Series controls are designed to reference either
one or two Johnson Controls P266 Series Electronic
Pressure Transducers to monitor condenser pressure.
P266 Series transducers are specialized versions of
the P499 Series Electronic Pressure Transducers
designed for use with P266 Series Fan Speed
Controls. See Table 3 for the available P266 Series
transducer models.
Refer to the P499 Series Electronic Pressure
Transducers Product/Technical Bulletin (LIT-12011190)
for detailed information on installing P266 Series
transducers.
Note: On P266 Series control applications that use
two P266 Series transducers, the P266 Series control
always references the transducer that is sensing the
higher pressure.

1. 24 VAC Class 2 at 1/4 A.
2. Factory default settings: Start Voltage is set to 40% of the supply line-voltage. End Voltage is set to 95% of the supply
line-voltage. Start Pressure is set to 44% of the P266 transducer’s total pressure range. End Pressure is set to 51% of the
P266 transducer’s total pressure range.

IMPORTANT: When two P266 Series transducers
are connected to a P266 Series control, the
transducers must be the same model (product code
number). Failure to connect the same P266 Series
transducer models to the P266 Series control can
result in erratic control behavior.
