ThermoSense
Wireless Communicating Thermostats
ThermoSense is a wireless touch-screen thermostat for fan coil units and DX terminal units. It measures room temperature and humidity, drives fan and valve relays, and sends data over NRF 2.4 GHz to a MachineSens gateway. BuildOT One then handles schedules, setpoint limits, remote control and BMS integration over BACnet or MQTT.

Your existing BMS (optional)BACnet or MQTT, through Pulse Convert+- Our smart gateway collects near real-time data from all wireless sensors within range, converts it into an easy-to-use JSON format, and publishes it via the MQTT protocol.
- Data can be transmitted to any local or cloud MQTT broker through Ethernet, LTE (4G), or WIFI.
- Integration to Building Management System (BMS) can be achieved using MQTT broker or through an external BACnet converter.
- ThermoSense wireless intelligent thermostats can be centrally controlled from MachineSens IoT Cloud Platform.
The MachineSens IoT Cloud Platform enables: –
- Monitoring & Control: ThermoSense wireless intelligent thermostat enables remote monitoring and control of the AC equipment.
- Data Analysis: IoT devices transmit this data to a cloud based central software system for real-time analysis and notifications.
- Optimal Setpoints: The IoT solution (Hardware + Software) enables automated or centralized control of the Terminal unit’s temperature to maintain comfort while minimizing energy consumption.
- Reporting: The system can generate energy usage reports (virtual metering), helping users understand their consumption patterns and make informed decisions.
- Programmed Schedules:Scheduling – Desired schedules can be programmed in the cloud-based software platform for control & monitoring. The IoT system can respond to demand response signals, reducing energy usage during peak periods. Specific times for system operation, such as when the HVAC should start or stop, temperature setting can be enabled or restricted.
The FCU and DX unit setpoints and operation can be optimized from the cloud platform.

Frequently asked questions
What can the ThermoSense thermostat control?
It has 4 relay outputs for fan control and 1 relay for the valve, with automatic or manual heating and cooling changeover and minimum and maximum setpoint limits.
How does it integrate with a BMS?
The gateway publishes thermostat data over MQTT. A BMS can read it from the MQTT broker or through an external BACnet converter such as Pulse Convert+.
How is it powered and mounted?
It takes 230V AC or 24V DC and can be flush mounted in a standard EU box or surface mounted.
