AB Industrietechnik TH Evolution room thermostat / fan coil controller, BACnet MS/TP BACnet points list

Updated 12 November 2026

Short answer

TH Evolution is a wall-mounted room controller for 2- and 4-pipe fan coils (3-speed or EC fans) with relays, 0-10 V outputs and inputs for remote sensors and contacts. The BACnet MS/TP version exposes sensor readings as Analog Inputs, output values, setpoints, offsets and tuning as Analog Values, input and relay states as Binary Inputs and Values, and regulation type, input functions, fan speed mode and display options as Multi-State Values.

BMS integration notes: AB Industrietechnik TH Evolution room thermostat / fan coil controller, BACnet MS/TP

Integration in brief

Set the device ID with parameters I62/I63 and the MS/TP address, then switch the unit with BV 2189, choose fan speed mode and occupancy settings, and adjust the heating/cooling setpoints. Read room temperature, the working setpoint and relay states.

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.

Network setup

BACnet device ID = I63 x 10000 + I62, set from the parameter menu.
MS/TP master or slave at 9600, 19200, 38400 or 76800 baud (PICS).

Watch out for

Use the setpoint AV that matches the regulation type: 2138/2139 for non 4-pipe, 2140 for 4-pipe.
Out-of-scale 0-10 V input reads 32000 (or 3200) on INPUT_AI3.

Integration notes

Names are printed with "(Note n)" markers that point to rounding and working-setpoint notes; the markers are dropped here.
Temperature units follow BV 2176 UNIT_C_F; written temperatures are rounded to 0.5 °C or 0.2 °F steps.
AV 3016 WORKING_SET is calculated from the setpoint parameters and is forced to fixed values (for example 70.0 °C) on antifreeze or sensor alarm.
BV 2129, 2130 and 2176 print two value texts (EC / 3-SPEED, STANDARD / WITH AUX RELAY, CELCIUS / FARENHEIT) without saying which is active.
Regulation type abbreviations: H=heating, C=cooling, R=electric heater, c/o=season changeover, auto=water sensor, rem.=remote contact, par.=parameter.

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 TH Evolution room thermostat / fan coil controller, BACnet MS/TP and exports what it actually has to Excel — free.
