Pelican TS250 RevC

The TS250 is a thermostat that measures measures carbon dioxide and temperature that can be used for long-term monitoring and demand control ventilation. The carbon dioxide sensor is optional.

Hub Highlights:

Does not display CO2 value on device. Display of CO2 value available on web-portal or app for authorized users
Pelican's site manager web-based software displays historical data via graphs and has configurable alarms. Additional hardware needed to connect to other building automation systems
Excellent performance on Hub CO2 accuracy testing protocols
Includes temperature and humidity sensors. Requires Wi-Fi connectivity and a subscription plan to view and configure devices

User interface

Can the sensor display the CO2 level to occupants? If yes describe.

Yes - Display available through web, account required

User interface

Can the sensor display a visual indicator to occupants that the CO2 level has exceeded a programmed threshold? If yes, describe (what does the indicator look like, what the default thresholds are, and can the threshold be changed).

Yes - Thermostat has a feature available to blink black dot on display to indicate a programmed alarm condition

Reporting capabilities

Can the sensor alert facilities (such as an email, text, or call phone application) when the CO2 level has exceeded a programmed threshold? If yes, describe (what does the indicator look like and can the threshold be changed).

Yes - The site manager can be used to configure alerts for elevated CO2 levels that are then sent by text or email.

Reporting Capabilities, Integration capabilities

How can the CO2 sensor data be logged? If proprietary software, describe (what type of account is needed, what logging intervals are available, what does it look like, and describe its capabilities including data download capabilities).

Wifi with proprietary software. The site manager allows viewing historical data via graphs. Data collection interval is automated and not adjustable. Data can not be downloaded from the website.

Integration capabilities

Can the CO2 sensor interface with a building automation system (BAS) or demand control ventilation (DCV) system controller? If yes, describe if integration capabilities are vendor specific.

Yes - Pelican BAS and Pelican Pearl DCV controller only

Integration capabilities

If sensor can interface with a BAS or DCV system controller, is additional hardware required?

Installation

Does the sensor require specialized software for installation? If yes, describe

Yes - Requires connecting to gateway and logging into web portal for setup

Installation

Does the sensor require specialized training for installation? If yes, describe

Operation

Does the sensor require on-going maintenance? If yes, describe?

Operation

Does the sensor require service contracts for ongoing data access? If yes, describe

Yes - The service contract for the first year is free. Multiple paid subscription options thereafter.
