The factory-installed PremierLink™ controller for
the water source heat pump unit is configurable with a variety
of Carrier space temperature sensors.
SPACE TEMPERATURE SENSOR (SPT) — A field-supplied
Carrier space temperature sensor is required to maintain space
temperature in sensor mode. There are three sensors available
for this application: the 33ZCT55SPT Space Temperature
Sensor with Override Button, the 33ZCT56SPT Space
Temperature Sensor with Override Button and Set Point
Adjustment, and the 33ZCT58SPT T58 Communicating Room
Sensor with Override Button, Set Point Adjustment, and
Manual fan control.
INDOOR AIR QUALITY CO
2
SENSOR — An indoor air
quality sensor is required for CO
2
level monitoring. Three
different CO
2
sensors are available for this application: the
33ZCSENCO2 sensor is an indoor, wall-mounted sensor with
an LED display, the 33ZCT55CO2 sensor is an indoor,
wall-mounted sensor without display (also includes a space
temperature sensor with override button), the 33ZCT56CO2
sensor is an indoor, wall-mounted sensor without display (also
includes a space temperature sensor with override button and
temperature offset).
