Integrator Helps Smart Thermostats Control Fujitsu Units
INTEGRATION SOLUTION: The Airzone Aidoo Pro helps two kinds of smart thermostats control Fujitsu Airstage indoor units.
PINE BROOK, N.J. — General HVAC Solutions America Inc. announced that the Airzone Aidoo Pro is a validated smart thermostat integration solution for Fujitsu Airstage indoor units, including for demand-response-capable applications.
The Airzone Aidoo Pro functions as a cloud-enabled protocol gateway that enables the Google Nest Learning Thermostat (fourth generation) and the ecobee Smart Thermostat Premium to operate as the primary control interface for Fujitsu Airstage inverter-driven HVAC systems, while preserving native Fujitsu Airstage modulation, safety logic, and fault protection, a press release from the company said.
Validation testing confirms stable cloud-to-cloud and wired thermostat operation, auto changeover functionality, minimum heat protection, and participation in utility demand-response programs when used with qualified smart thermostats.
