A Definition
Advanced Thermostat = Programmable, Communicable
Thermostat
Synonyms: web-enabled thermostat, connected thermostat, smart thermostat

Components and Features
![Page 5: The benefits of advanced thermostats](https://reader036.vdocuments.net/reader036/viewer/2022070319/5583decad8b42ace2f8b54ad/html5/thumbnails/5.jpg)
Hardware
At core, they are standard programmable thermostats One-to-one replacement of SPT Not for multi-zone or VAV systems
More input and output channels Option to expand system
Increased power needs Usually not a problem

Communications
Thermostat to the world NOT thermostat to HVAC unit
Methods Wi-Fi Ethernet Mesh networks
No “best” method
![Page 7: The benefits of advanced thermostats](https://reader036.vdocuments.net/reader036/viewer/2022070319/5583decad8b42ace2f8b54ad/html5/thumbnails/7.jpg)
Software
Mostly cloud based On the web Mobile platforms
Easier to use Remote access Collect data
Presentation of trends Alerts

Market Transformation Potential
![Page 9: The benefits of advanced thermostats](https://reader036.vdocuments.net/reader036/viewer/2022070319/5583decad8b42ace2f8b54ad/html5/thumbnails/9.jpg)
Fulfill Original Promise of SPTs
Standard programmable thermostats (SPTs) were kind of a disappointment
ENERGY STAR suspended labeling Lack of usability Difficulty substantiating savings
Advanced thermostats more usable! Will (hopefully) save the energy SPTs
were supposed to

Massively Increase Data
Collecting, transmitting, recording 24/7 Indoor/outdoor air, binary output
controls, etc. Highly frequent intervals Never captured systematically
before So?
At building: better understand your equipment
Industry: better understand use patterns/equipment

Change Maintenance Staff Role
Reduce burden on maintenance staff Remote investigation/triage/remedies
= less wasted time = lower cost + more time for other projects
New business models for HVAC contractor Greater transparency to unit means
cost savings and better, more proactive service

Modular, “Light” BMS
Thermostat is not just a thermostat Linchpin of software-based controls system
Can control HVAC, lighting, plug-load, etc.
Expansion is modular and piece meal
Will not replace full BMS, but can act as cheaper “down market” substitute Cost: $750-$1,250/thermostat (incl.
labor)

The Learning Curve
![Page 14: The benefits of advanced thermostats](https://reader036.vdocuments.net/reader036/viewer/2022070319/5583decad8b42ace2f8b54ad/html5/thumbnails/14.jpg)
Barriers to Adoption
Power Mostly NOT an issue, but can be if
misunderstood Communications
There is always a solution that works…
…but installers do not understand networks
Wringing out the value Features are many and complicated Market/installers must grow
comfortable

Programs Can Help
Train installers on power/networks How to properly configure power How to setup Wi-Fi and mesh networks
Support growth in understanding of lesser-used, value-added features Case studies for distribution to wider
market Workshops with installers to share success
stories and train on common features
