Daikin ONE+ Smart Thermostat DTST-CWBSA-NI-B
The Daikin ONE+ DTST-CWBSA-NI-B is the smart thermostat Daikin describes as the first to offer full two-way communication with Daikin HVAC systems. It works with compatible Daikin equipment, including R-32 unitary split systems, gas furnaces, ductless mini-splits, SkyAir, and VRV indoor units. It doesn't simply switch equipment on and off. It exchanges data with the system for synchronized operation, error and service notifications, and over-the-air software updates. A 3.5" full-color capacitive touchscreen sits behind toughened glass and is framed by an anodized aluminum dial. An LED light bar along the bottom glows red in heating and blue in cooling. Built-in Wi-Fi links the thermostat to the SkyportHome app, Amazon Alexa, and Google Assistant, so it suits homeowners and contractors building a fully connected Daikin comfort system.
Is the Daikin ONE+ DTST-CWBSA-NI-B the Right Thermostat for Your System?
Compatibility depends on the equipment, not the size of the home. Daikin lists the ONE+ by model family. On the unitary side, that includes R-32 outdoor units beginning with DC_VS, DC7TC, DH_VS, and DH_TC, air handlers beginning with D_VE, A_VE, and AMVT, CAPE and CHPE coils, the MBVK modular blower, and Daikin communicating gas furnaces. It draws power from the indoor unit or translation adaptor and connects over a single 4-core cable. Check your model numbers against Daikin's list before you order.
Ductless and commercial-style systems need one more part. Daikin mini-split, multi-split, SkyAir, and VRV indoor units connect through the DAPT-ONE-VMS translation adaptor, and certain mini-split models also need a specific S21 adapter. If your system isn't Daikin communicating equipment, a thermostat built for that equipment is the better choice.
Ideal for: New Daikin R-32 communicating heat pump, air conditioner, and furnace installations, Daikin ductless and VRV systems that need a wall-mounted smart control, homeowners who want app and voice control, and contractors using SkyportCare remote monitoring.
Need a different style? The Daikin One Touch Smart Thermostat DTST-TOU-A is another control option for Daikin communicating unitary equipment, with a touchscreen interface and app control.
Compatibility information is a general guideline only. Actual thermostat requirements depend on your equipment model, communication type, required adaptors, and wiring. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
Which Daikin equipment is the DTST-CWBSA-NI-B compatible with?
Daikin lists R-32 unitary outdoor units beginning with DC_VS, DC7TC, DH_VS, and DH_TC, air handlers beginning with D_VE, A_VE, and AMVT, CAPE and CHPE coils, the MBVK modular blower, and DR and DD communicating gas furnaces. Ductless, SkyAir, and VRV indoor units are also supported with the right adaptor. Confirm your exact models on the submittal sheet.
Can the Daikin ONE+ control a Daikin ductless mini-split?
Yes, with the DAPT-ONE-VMS translation adaptor. Some S21 indoor units, including certain FTXV, CTXV, FTXF, FTXQ, and FTXM models, also need a specific S21 adapter (KRP067A41E, KRP980B2E, or KER087A41). The submittal sheet shows which adapter each model needs.
What wire and run length does the Daikin ONE+ require?
Daikin specifies field-supplied 18 AWG, 4-core, non-shielded stranded wire with a maximum length of 125 ft and one connection. The thermostat takes its power from the indoor unit or translation adaptor.
How many wireless room sensors can connect to one ONE+ thermostat?
Up to 8 Daikin ONE wireless RHT sensors (DSEN-TH-BWS-A). They are battery powered and need no wiring, and each should be mounted in a room within the same controlled zone to improve comfort compared with the thermostat alone.
How do I get the 12-year warranty on the DTST-CWBSA-NI-B?
Register the thermostat online within 60 days of installation. The 12-year coverage applies to owner-occupied residences; without registration, coverage lasts up to 5 years. Non-owner-occupied residences can receive up to 10 years with registration, and commercial installations are covered for up to 5 years. Some states do not allow coverage to be conditioned on registration.
Does the Daikin ONE+ work with Alexa, Google, or a whole-home automation system?
Yes. It supports voice control with Amazon Alexa and Google Assistant and app control through SkyportHome. Its open API allows integration with home control systems such as Control4 and Crestron. Compare other options in our thermostats and controls collection.
