A350P Series: Temperature Modular Control

Systems 350 Modular Temperature Control System: A350P Series

Description

The A350P is an electronic, proportional plus integral temperature control.  This control has an integration feature that forces the control point to match the setpoint. Over time, the A350P will control the heating/cooling equipment to balance the system load at the control setpoint.
As are all System 350™ products, the A350P control is housed in a NEMA 1, high-impact plastic enclosure. The modular design provides easy, plug-together connections for quick installation and future expandability.

Features
  • Field-selectable proportional only or proportional plus integral control
  • Plug-together connectors and 35 mm DIN rail mounting eliminate wiring between models and reduce installation costs
  • Ten segment LED displays percent of output signal
  • Field-selectable reverse or direct-acting mode
  • Minimum output adjustable from 0 to 60%
  • Two models cover a wide setpoint range of -30 to 250°F (-35 to 121°C)

Applications

  • Modulating heating and cooling valves
  • Maintain mixed air duct temperature via damper modulation
