The A350R Reset Controller is designed to raise or lower the setpoint of supply water
temperature based upon a proportionate drop or rise in temperature at the master (outdoor) sensor.
The control output is a Single-Pole, Single-Throw (SPST) normally open relay with Light-Emitting Diode (LED) indication.
The adjustable differential enables the user to match the amount of control (maximum to minimum)
required for a given application.
An adjustable reset ratio adapts to a variety of weather zones and to the specific heat loss
characteristics of most buildings.
