1. Complete account setup and connect the Hub

Follow the in-app instructions until the Sensor Placement portion.

2. Comfort Sensor placement

The placement of the Comfort Sensor is unaffected when installing a Hardware

Kit on an RTU. Place the sensor according to the in-app instructions on a main

supply air vent.

3. Filter Sensor placement for RTU Package Units

i. If the filter is located in a wall or ceiling return vent, follow the prompts in the

app and place the Filter Sensor behind the filter as typically done.

ii. If the filter is in-system and therefore inaccessible on the rooftop, place the

Filter Sensor inside a return air vent even if no filter is present.

4. Water Sensor placement for RTU Package Units

Given rooftop package units do not have a secondary drain pan, the Water

Sensor cannot be placed as directed in the app. Instead, place the Water

Sensor in the water heater drain pan and rename the location to ‘Water

Heater’ in the app.

5. Condenser nameplate photo

If the condenser is safely accessible, take a photo of the nameplate showing the

serial number.

If the condenser is inaccessible, please email the serial and model number to

support@smartac.com at the end of onboarding. If these details are unknown,

please provide any available system information such as type (gas furnace or heat

pump), speed (constant, dual, or variable), tonnage, and year of manufacture.
