Can I Control Multiple Zones Using an ADC-T3000?

No, you cannot control multiple zones using an ADC-T3000. The ADC-T3000 Z-Wave Plus Thermostat from Alarm.com can only interface with one HVAC system zone at any given time. Each zone on the system should have its own thermostat controller. They can all be on the same Z-Wave network.

The Alarm.com ADC-T3000 is a smart Z-Wave Plus thermostat. It can interface with almost any Z-Wave controller or hub, but it is primarily designed to interface with security systems that connect with Alarm.com. The thermostat offers complete temperature control, as well as fan control and humidity control capabilities. Pairing the thermostat with your Z-Wave network will allow you to control the device remotely, and you can also include it with smart scenes for automatic operation.

Some users with HVAC systems that operate across multiple zones wonder if there is a way to have the ADC-T3000 control multiple HVAC zones. Unfortunately, that is not possible. If you were to connect an ADC-T3000 with such a system, then you would only be able to assign it to one zone. The ADC-T3000 would control that one zone, including its temperature, fan setting, and humidity settings, if applicable. You would then need additional ADC-T3000 units to control the other zones on the HVAC system.

One feature that is available for the ADC-T3000 is the ability to interface with multiple temperature sensors, which are known as the Alarm.com ADC-S2000-T-RB. These devices pair with the same Z-Wave network as the ADC-T3000, and you then complete the integration between the thermostat and the temperature sensors through Alarn.com. Up to ten (10) of these units can pair with a single ADC-T3000 Thermostat. Each ADC-S2000-T-RB will then be used to detect the temperature in a different area, away from the ADC-T3000 itself.

However, these different "temperature zones" do not represent multiple "HVAC zones", and the ADC-T3000 will only be able to control one zone on an HVAC system at any given time. The purpose of the ADC-S2000-T-RB devices is to get multiple temperature readings across a larger area. The ADC-T3000 can then control the single HVAC system zone accordingly to provide more effective heating and cooling based on the readings from the multiple sensors. But in any case, the ADC-T3000 will only be controlling one HVAC system zone.
