Distech Controls ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities) BACnet points list

Updated 7 November 2026

Short answer

The ECY-PTU-207 / 208 and ECY-TU-203 is a Distech Controls Eclypse terminal unit controller on BACnet IP that ships with preloaded fan coil, chilled beam/ceiling and heat pump applications, plus lighting and sunblind control and outside-air damper/CO2 control. The preloaded program exposes a fixed set of value objects for setpoints, occupancy, mode, fan, valve, light and blind control. It is configured from the controller's web pages or the EC-gfxProgram Configuration Assistant.

This page lists 167 BACnet objects for the Distech Controls ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities) — 127 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Distech Controls’s own free documentation, linked below.

BMS integration notes: Distech Controls ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities)

Integration in brief

Command occupancy with MV 2 and the mode with MV 1, write the occupied setpoints AV 40 and AV 41, and read back MV 14, MV 11, AV 1 and MV 16. Leave MV 3 at Auto unless the BMS should pick the fan speed.

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.

Object	Name	Why	Access
MV 2	OccupancyCmd	Occupancy command from the BMS	Write
MV 1	HvacModeCmd	HVAC mode command (auto, heat, cool, off)	Write
MV 3	FanSpeedCmd	Fan speed command (auto, off, low, med, high)	Write
AV 40	OccCoolSp	Occupied cooling setpoint	Write
AV 41	OccHeatSp	Occupied heating setpoint	Write
MV 14	OccupancyStatus	Effective occupancy state	Read
MV 11	HvacModeStatus	Actual HVAC mode	Read
AV 1	SpaceTemp	Space temperature used for control	Read
MV 16	FanSpeedSt	Actual fan speed	Read
BV 2	CondSensorSt	Condensation alarm; cooling valve closes	Read

Enable & remote start

Write MV 2 OccupancyCmd for occupancy and MV 1 HvacModeCmd for the mode; any value other than Auto forces the unit into that mode. MV 3 FanSpeedCmd set to Auto leaves the fan to the control loop.

Sensors & values from the BMS

The guide says AV 1 SpaceTemp and other measured values can be overridden through the BACnet priority array (it calls this a testing feature). MV 5 MotionSensor can be written from the network; the guide says to use a priority lower than 14 to override local control.

Network setup

Eclypse controllers connect over Ethernet; the guide reaches the configuration pages through the controller's IP address or factory host name.
Master/slave and remote light/blind groups use room numbers (AV 81 CtrlRoom and the light/blind room values).

Watch out for

Temperatures are in °C in this guide.
Configuration values (system type, valve and fan types) are commissioning settings; don't write them cyclically.

Distech Controls ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities) BACnet objects

Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.

Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes

Objects are documented one per section in the guide's Variables chapter; hardware inputs and outputs are described there too but are not listed here.
The guide has no read/write column, so access is inferred from each object's description: values the guide says are set, configured or received from the BMS are marked writable; values it describes as displayed (measured or calculated) are read-only, although the guide allows overriding some of them for testing.
Which objects are used depends on the configured system type, fan type, valve types and input configuration.
This is the Eclypse Facilities edition of the guide; the older 2016 guide for the same models lists a few fewer lighting objects.
Left out because the guide prints two different instance numbers for them (section heading vs table row): UnoccOccDelay (AV 32), Light2Room (AV 72), Light3Room (AV 73), RulesNumber (MV 8).

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 ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities) 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 Distech Controls ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities)

How many BACnet points does the Distech Controls ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities) have?

This list has 167 BACnet objects: 96 analog values, 31 binary values, 40 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Distech Controls ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities) BACnet points are writable?

127 of the 167 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done. The source has no read/write column, so this is inferred from object type.

Where is the official Distech Controls ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities) BACnet documentation?

The source is ECY-PTU 207/208 and ECY-TU-203 Preloaded Applications with Eclypse Facilities User Guide (ECY-PTU-207_208-ECY-TU-203-EF-Preloaded_UG_12_EN), revision 2025-02 (version 1.3), published free by Distech Controls at https://docs.distech-controls.com/api/khub/documents/ymc5_~K~Ua3Rt28hOJRDAQ/content.

What are the minimum BACnet points to integrate the Distech Controls ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities)?

Start with MV 2 OccupancyCmd (Occupancy command from the BMS); MV 1 HvacModeCmd (HVAC mode command (auto, heat, cool, off)); MV 3 FanSpeedCmd (Fan speed command (auto, off, low, med, high)); AV 40 OccCoolSp (Occupied cooling setpoint); AV 41 OccHeatSp (Occupied heating setpoint); MV 14 OccupancyStatus (Effective occupancy state); MV 11 HvacModeStatus (Actual HVAC mode); AV 1 SpaceTemp (Space temperature used for control); MV 16 FanSpeedSt (Actual fan speed); BV 2 CondSensorSt (Condensation alarm; cooling valve closes).

How do I enable BMS control of the Distech Controls ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities)?

Write MV 2 OccupancyCmd for occupancy and MV 1 HvacModeCmd for the mode; any value other than Auto forces the unit into that mode. MV 3 FanSpeedCmd set to Auto leaves the fan to the control loop.

Can the BMS supply sensor values to the Distech Controls ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities)?

How do I check these points on the real ECY-PTU-207 / 208 and ECY-TU-203 preloaded applications (Eclypse Facilities)?

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.
