Outlet Temperature Sensors
The Control System includes a Dual Temperature Sensor which is installed in the hot water
outlet of the unit. This sensor contains two identical Type J thermocouples. The first
thermocouple connects directly to the Temperature Controller to provide feedback PID control
for the outlet water temperature. The second thermocouple connects to the Over-Temperature
Indicator/Switch in the Control Box.
1.3.4
Boiler Water Inlet Temperature Sensor
An additional Temperature Sensor (Type J thermocouple) is provided with the Control System.
This Sensor is attached to the
unit’s boiler water inlet. This sensor is connected to the
Temperature Controller to provide a real-time indication of the inlet water temperature.
