- Modular design enables stage, display and transformer modules to be purchased and installed as necessary
- Adjustable master reset set point (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
- 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
- Adjustable setback temperature saves energy by lowering the supply temperature set point at night or during unoccupied periods
- 3.2 V-A power consumption
- Reverse acting
- Includes A99BB-300C and A99BC-25C sensors
