RTD Temperature Offset Adjustment 

The Entering Water RTD and LWT Manifold RTD (Dual Circuits or Master/Slave Systems only) are adjustable. To 
change, enter a temperature offset into the RTD Temperature Offset Screen. Only change the offset if there is a 
discrepancy between the sensor reading and the actual temperature.
