How to Install Thermistor Sensors

As seen in the diagram below, one thermistor sensor detects the temperature of the in-coming water and another the out-going water.

1. Temperature data of the in-coming and out-going water are transferred from the thermistor sensors to the micro-computer.
2. The micro-computer gives command to the furnace according to the temperature data. Then the furnace will adjust its amount of heat.

Below is an example of how to install a thermistor sensor in a pipe.
