ClimateMaster Tranquility Large Water-to-Water (SWT) 20-80 ton BACnet points list
Updated 11 November 2026
Short answer
Each SWT module controller works under a bank controller and can be read by a BMS over BACnet MS/TP or BACnet IP (Gig-E port only). The 159-point list is mostly status: circuit pressures, temperatures, superheat and subcool, EEV positions, loop valves and flows, compressor status and run time, out-of-range sensor flags and alarms, plus manual-mode test commands and the bank's leaving-water targets.
This page lists 159 BACnet objects for the ClimateMaster Tranquility Large Water-to-Water (SWT) 20-80 ton — 41 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from ClimateMaster’s own free documentation, linked below.

BMS integration notes: ClimateMaster Tranquility Large Water-to-Water (SWT) 20-80 ton
Integration in brief
Set the module controller address on its three rotary switches and choose MS/TP with the Comm Selector rotary (position 1), or use the Gig-E port for BACnet IP. The modules are run by their bank controller; a BMS mainly monitors module status and alarms and can read or adjust the bank's leaving-water targets.
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
BV 2076 chiller_run_1 is the module enable from the bank controller; the manual does not describe a separate BMS enable.
Heartbeat & communication loss
BV 2068 comm_lost_1 alarms when the module loses communication with the bank controller; BV 2152 mod_comm_tx_stat_1 shows the module's communication transmit status.
Network setup
- Address: set the hundreds, tens and ones rotary switches to the controller address (for example 0-0-1 for 001), before powering the unit.
- Comm Selector rotary switch at 1 = BACnet MS/TP.
- BACnet IP is only on the Gig-E Ethernet port; connect a CAT 5e cable there.
Watch out for
- Manual-mode objects override normal control; check BV 2210 manual_mode_1 and AV 2175 man_mode_remain_time_1 before leaving a module.
- The list gives no engineering units; check them on the device.

Integration notes
- The list has no read/write or units column. Access is inferred from the description: setpoints, targets, manual-mode controls, resets and enables are marked writable, everything else read-only.
- Descriptions are the list's own Description column; when the Name column says something different it is shown in brackets.
- Several points (EEV, valve, solenoid and reversing-valve 'Manual' objects) only act when the module is in manual mode.
- The list has some label slips that are kept as printed: c1_man_hgs_1 and c1_man_li_1 are both labelled Manual C1 Hot Gas Solenoid, c2_man_li_1 is labelled Manual C1 Liquid Injection, and BV:2174 c2_minimum_off_1 is labelled C1 Compressor Off Delay.
- AV:2239 manual_sysmode_1 and BV:2239 c1_disable_1 share instance 2239 in different object types, as printed.
- Object names end in _1 as printed.
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 Tranquility Large Water-to-Water (SWT) 20-80 ton 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 ClimateMaster Tranquility Large Water-to-Water (SWT) 20-80 ton
How many BACnet points does the ClimateMaster Tranquility Large Water-to-Water (SWT) 20-80 ton have?
This list has 159 BACnet objects: 62 analog values, 97 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which ClimateMaster Tranquility Large Water-to-Water (SWT) 20-80 ton BACnet points are writable?
41 of the 159 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 ClimateMaster Tranquility Large Water-to-Water (SWT) 20-80 ton BACnet documentation?
The source is Tranquility Large Water-to-Water SWT Series - Installation, Operation & Maintenance Manual (Controller Points List) (C97B0004N07), revision 2026-03-09, published free by ClimateMaster at https://files.climatemaster.com/Commercial/Water-to-Water-Units/Tranquility/SWT/Resources/C97B0004N07-SWT-IOM.pdf.
What are the minimum BACnet points to integrate the ClimateMaster Tranquility Large Water-to-Water (SWT) 20-80 ton?
Start with AV 2156 cool_temp_stp_1 (Bank chilled water target); AV 2155 heat_temp_stp_1 (Bank hot water target); BV 2069 reset_alarms_1 (Reset all module alarms); BV 2073 module_run_1 (Module running); AV 2158 sysmode_1 (Module mode); BV 2074 module_ok_1 (Module condition); AV 2147 loop1_leaving_temp_1 (Loop 1 leaving water temperature); BV 2075 manager_lockout_alrm_1 (Module locked out); AV 2167 mod_act_mod_alarms_1 (Active module alarms).
How do I enable BMS control of the ClimateMaster Tranquility Large Water-to-Water (SWT) 20-80 ton?
BV 2076 chiller_run_1 is the module enable from the bank controller; the manual does not describe a separate BMS enable.
Does the ClimateMaster Tranquility Large Water-to-Water (SWT) 20-80 ton need a BACnet heartbeat or have a communication timeout?
BV 2068 comm_lost_1 alarms when the module loses communication with the bank controller; BV 2152 mod_comm_tx_stat_1 shows the module's communication transmit status.
How do I check these points on the real Tranquility Large Water-to-Water (SWT) 20-80 ton?
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.
