Current Standard Solution:
Airoverse offers the ability to control a unit heater with a SmartNode using the Single Stage Equipment (SSE) profile.
Opportunity :
There are scenarios where a customer wants visibility and control of the Unit Heaters in a building.
How does it work? :
Let's assume the unit heater has a 24v power source. We want to tap into that power supply to power our SmartNode. Next, you want to connect your heating call through Relay 1 on the SmartNode and your fan call (if applicable) through Relay 2. Finally, you want to connect your Airoverse temperature /humidity sensor to the RTS input and a supply air temperature sensor (10K Type 2) to the TH1 input on the SmartNode. See the connection diagram below:
Configuration
From the Select Module Type screen for the SmartNode,
- Click the Single Stage Equipment option.
- Follow the instructions for pairing as shown below.
The configuration screen displays the following.
- Relay-1
- Relay-2
- Thermistor-1
- Thermistor-2
- Analog-in 1

- Configure the required parameters.
- Click Set to confirm the configuration.
The Single-stage equipment profile using the SmartNode is configured and ready to control the equipment.
The profile data that is aggregated by the CCU can be visualized in the portals.
Note: You can configure SSE modules from CCU but can reconfigure the values from the internal portal.
Post Configuration
Once an SSE profile for using the SmartNode is configured for a space the same would reflect in CCU as below.
And reflects in the portals as shown below:
Result:
- Unit heaters now have the ability to be monitored and controlled remotely.
- Using a SmartNode with the SSE profile unit heaters can be in setback mode based on the vacation or the unoccupied schedule.
