Configuring the analog inputs for volumetric offset control
Use volumetric offset control (VOC) when you want to maintain an offset setpoint between the total supply and total exhaust air flows
including any fume hoods in the monitored space. To configure for volumeteric offset control, configure both AI-3 and AI-4 for air flow.
Use AI-3 and AI-4 for total supply and total exhaust air flows respectively.

Settings
icon to enter the
Settings
menu.

Configuring the analog output for air flow control
If you are controlling flow, map the analog input to the corresponding analog output as required by the specific application. Refer to the
submittal package wiring diagrams to map the analog output correctly.
If you are controlling volumetric offset, map AI-3 and AI-4 to the corresponding analog outputs as required by the specific application.
To map the analog output, refer to the submittal package wiring diagrams. Use AO-3 for the supply valves and AO-4 for the general
exhaust.
Changing the operating mode for air flow control
Each of the four analog outputs of the FMS-2000C controller can be configured for the following operating modes:
•
Direct operating mode
•
PID operating mode
In direct operating mode, the output tracks the mapped analog input directly or inversely. The PID operating mode may or may not
employ the proportional-integral-derivative scheme for closed-loop control of the analog output. The range of the output can or cannot
include an offset. This is independent of the mode the analog output is configured to.
To change the operating mode, complete the following steps:
1. On the home screen, tap the
Settings
icon to enter the
Settings
menu.
2. To view analog input settings, tap
Analog I/O
.
3.
To find the analog output you want to change the operating mode for, swipe left.
4. On the
ANALOG

.
5. To change the operating mode, expand
Operating Mode
arrow and tap
Direct Analog
or
PID Analog
.
6. Collapse
Operating Mode
