Verdant VX4 Energy Management Thermostats with BACnet Integration BACnet points list
Updated 4 November 2026
Verdant VX4 thermostats talk to each other over a proprietary 900 MHz mesh, and one Online Connection Kit puts the whole network on the building's BACnet network. Every room gets the same 15 objects; the object instance is a fixed base number per object plus the room number. The sheet does not name BACnet IP or MS/TP; its network drawing shows the kit on the building automation LAN.
This page lists 15 BACnet objects for the Verdant VX4 Energy Management Thermostats with BACnet Integration — 7 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Verdant’s own free documentation, linked below.

BMS integration notes: Verdant VX4 Energy Management Thermostats with BACnet Integration
The sheet lists 15 objects per room, reached through the Online Connection Kit; work out each room's instances from the base numbers plus the room number read as hex. Write System Mode, Fan Speed and Guest Setpoint per room; read Room Temperature, Occupancy State, Thermostat Status and the setpoints. Watch Gateway Online Status for loss of the thermostat network.
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.

| AV 200000 | Heat Setpoint | Heating setpoint in effect | Read |
| BV 1400000 | Gateway Online Status | 0 = offline, 1 = online | Read |
Network setup
- One Online Connection Kit links the 900 MHz thermostat mesh to the BACnet network; no Wi-Fi is needed at the rooms.
- Object instance = printed base + room number read as hex and converted to decimal (room 101 -> 257, so Room Temperature is AV 500257).
Watch out for
- Fan Speed reads back 0-3 but must be written with 0, 1, 85, 170 or 254.
- Cool Setpoint and Heat Setpoint are read-only; use Guest Setpoint to change the room setpoint.
- Min/Max Setpoint Limit and Heat EQP Lockout are configuration values; don't write them cyclically.

Integration notes
- Instances shown are the printed base values. The sheet gives each room's instance as base + hex2dec(room number): read the room number as a hexadecimal number, convert it to decimal and add it to the base. For example, room 101 is 0x101 = 257, so its Room Temperature is AV 500257. The sheet gives no worked example, so confirm against a discovered device.
- Cool Setpoint and Heat Setpoint are read-only; the writable setpoint is Guest Setpoint (60-90 °F).
- Fan Speed uses different codes for reading and writing (see states).
- Thermostat Status combined with System Mode gives the heating/cooling state; values 2 and 3 mean the room is in setback (unoccupied).
- The spec sheet does not state the BACnet transport; the network drawing places the Online Connection Kit on the building automation LAN.
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 VX4 Energy Management Thermostats with BACnet Integration and exports what it actually has to Excel — free.
