(BAYSENS108*)
This electronic sensor features four system switch settings
(Heat, Cool, Auto, and Off) and two fan settings (On and
Auto). It is a manual or automatic changeover control with
dual setpoint capability.
Compressor Motor Winding
Thermostats
CSHD Compressors
The compressors contain an internal line break overload
which stops the compressors under a number of operating
92
conditions that cause excessive motor temperature. These
include rapid cycling, loss of charge, abnormally high
suction temperatures, excessive amperage, phase loss
and low voltage
CSHN Compressors
PTC sensors are embedded in the motor windings of each
Scroll compressor. These sensors are wired to the
protection module which protects the motor from over
temperature that can occur under a number of abnormal
operating conditions. These include rapid cycling, loss of
charge, abnormally high suction temperatures, low voltage
and excessive amperage.
VZH Variable Speed Compressors
Over current and over torque protection for VZH
compressors are provided by the inverter.
