The Johnson Controls A350RS-1C 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 A350RS-1C can be used as a standalone device or in conjuction with plug-together acessory modules. Typical applications include reset of single or multistage boilers.
Features
The A350RS-1C's modular design enables stage, display, and transformer modules to be purchased and installed as necessary. An adjustable master reset setpoint (M.R.S.) enables the user to select a master (outdoor) sensor temperature starting point for the supply reset ramp. Adjustable minimum and maximum supply temperature permits compliance with equipment manufacturer’s specifications while the selectable warm weather shutdown temperature saves energy by disabling equipment when the master sensor temperature rises to a point where heating is no longer required. The adjustable setback temperature saves energy by lowering the supply temperature setpoint at night or during unoccupied periods.
