AFA 1000/RM
The AFA1000/RM model is a wall mounting Room differential pressure controller that is suitable for controlling the supply air into a room using a damper, valve or Inverter and includes the following features:-
- Back lit graphic display with a visual area of 56x27mm showing the room pressure (Pascals or Ins/wg) with VAV out Bar Graph. In an alarm condition the display will toggle between the room pressure and alarm condition.
- Audio Visual Alarm – Audible alarm with Red, Amber and Green LED’s.
- Password protected pushbutton set up and calibration menus with on screen instructions.
- 3 Relay Inputs configurable as:- Night Setback /Emergency / Door switch.
- 3 Relay outputs activated by any of the 3 inputs or any of the alarm conditions.
- VAV output to control either VAV damper, Venturi valve or Fan Inverter drive.
- Full PII VAV differential pressure set point control with optional door switch input.
- Com Port – RS485 for connections to a laptop for diagnostics and configuration of the monitor or for connection via a local Modbus RTU network for remote logging with real time graphical displays using the AFA Network software or for direct connection to a BMS system.
