The Proliphix thermostat provides two remote (external) sensor ports. This release
supports Analog and Thermistor sensors (go to Proliphix.com for a complete list of
supported sensors).
Analog
sensors convert temperature measurements as Fahrenheit degrees to a voltage
which can be sensed by the thermostat. Analog sensors are active devices which
require power from the thermostat. The Analog sensor is polarized and must be
connected as shown in
Table 3
.
Thermistor
sensors are passive devices which represent thermal measurements as
electrical resistance. Thermistors do not require power from the thermostat. The
Thermistor sensor is not polarized; either lead can be connected as shown in
Table 3
.
