Johnson Controls ATC1100 Fan Coil Controller - Application #2007 (Two-Pipe, On/Off Valve, Var-Speed Fan, On/Off Damper) BACnet points list

Updated 6 November 2026

Short answer

Application #2007 is one of the fan coil applications for the Johnson Controls ATC1100 (2 UI, 2 BI, 2 BO, 3 RO, 2 CO) Advanced Terminal Unit Controller, which connects over BACnet MS/TP (it can also run N2 or Modbus). It drives a two-pipe fan coil with on/off valve control, a variable-speed fan and an optional on/off fresh-air damper. Points cover unit enable, occupancy and mode commands, network setpoint and network sensor overrides, fan, valve and damper status, PID tuning, fault detection flags and the controller's network settings.

This page lists 208 BACnet objects for the Johnson Controls ATC1100 Fan Coil Controller - Application #2007 (Two-Pipe, On/Off Valve, Var-Speed Fan, On/Off Damper) — 140 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Johnson Controls’s own free documentation, linked below.

BMS integration notes: Johnson Controls ATC1100 Fan Coil Controller - Application #2007 (Two-Pipe, On/Off Valve, Var-Speed Fan, On/Off Damper)

Integration in brief

Set the controller to BACnet MS/TP (FC Comm Mode Wired Field Bus) with an MS/TP address of 4-127, then enable the unit with Unit Enable Mode, drive occupancy through Occupancy Schedule and write Network Setpoint (Spt Source defaults to Network Input). Read unit status, effective occupancy, zone temperature and the fan state.

Minimum points to map

The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Enable & remote start

Unit Enable Mode (Shutdown or Enable, default Enable) turns the unit off or on. Effective occupancy follows Occupancy Override first, then the bypass timer, Occupancy Schedule and the occupancy sensor. System Mode Determination is the writable mode command (cool only, heat only, fan only and others). The note says a network mode command takes priority over the summer-winter changeover input.

Sensors & values from the BMS

With Spt Source at Network Input (the default) the zone setpoint comes from Network Setpoint (default 22 °C). Network Override Zone Temperature, Network Override Outdoor Air Temperature and Network Override Indoor Air Quality are writable network inputs; a network CO2 value takes priority over the local sensor, and summer-winter setpoint compensation only works with a reliable network outdoor air temperature.

Integration notes

Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the ATC1100 Fan Coil Controller - Application #2007 (Two-Pipe, On/Off Valve, Var-Speed Fan, On/Off Damper) and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.

Questions about the Johnson Controls ATC1100 Fan Coil Controller - Application #2007 (Two-Pipe, On/Off Valve, Var-Speed Fan, On/Off Damper)

How many BACnet points does the Johnson Controls ATC1100 Fan Coil Controller - Application #2007 (Two-Pipe, On/Off Valve, Var-Speed Fan, On/Off Damper) have?

This list has 208 BACnet objects: 108 analog values, 100 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

What are the minimum BACnet points to integrate the Johnson Controls ATC1100 Fan Coil Controller - Application #2007 (Two-Pipe, On/Off Valve, Var-Speed Fan, On/Off Damper)?

Start with MV 28002 Unit Enable Mode (Unit on/off: 0=Shutdown, 1=Enable); MV 28048 Occupancy Schedule (Occupancy from the BAS schedule); MV 28006 System Mode Determination (Mode command (cool only, heat only, fan only...)); AV 28063 Network Setpoint (Zone setpoint written by the BAS, °C/°F); MV 28000 Unit Status (Heat, cool, fan only, satisfied or off); MV 28049 Effective Occupancy (Occupancy in effect); AV 28085 Operational Zone Temperature (Zone temperature in use, °C/°F); AV 28072 Fan Speed AO (Fan speed output, %); MV 28081 Condensate Alarm BI (Condensate alarm input: 0=Normal, 1=Alarm).

How do I enable BMS control of the Johnson Controls ATC1100 Fan Coil Controller - Application #2007 (Two-Pipe, On/Off Valve, Var-Speed Fan, On/Off Damper)?

Unit Enable Mode (Shutdown or Enable, default Enable) turns the unit off or on. Effective occupancy follows Occupancy Override first, then the bypass timer, Occupancy Schedule and the occupancy sensor. System Mode Determination is the writable mode command (cool only, heat only, fan only and others). The note says a network mode command takes priority over the summer-winter changeover input.

Can the BMS supply sensor values to the Johnson Controls ATC1100 Fan Coil Controller - Application #2007 (Two-Pipe, On/Off Valve, Var-Speed Fan, On/Off Damper)?

With Spt Source at Network Input (the default) the zone setpoint comes from Network Setpoint (default 22 °C). Network Override Zone Temperature, Network Override Outdoor Air Temperature and Network Override Indoor Air Quality are writable network inputs; a network CO2 value takes priority over the local sensor, and summer-winter setpoint compensation only works with a reliable network outdoor air temperature.

How do I check these points on the real ATC1100 Fan Coil Controller - Application #2007 (Two-Pipe, On/Off Valve, Var-Speed Fan, On/Off Damper)?

Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
