Minimalistic Design, Smart Control

The Heatmiser neoStat – Pro embodies simplicity with its minimalist design and soft-glow digital display, providing essential temperature information for easy control. This thermostat introduces a new design language for Heatmiser products, combining minimalist aesthetics with smart control through the neoApp or smart home platforms like Amazon Alexa, Google Assistant, or Apple HomeKit.

Beyond its sleek design, the neoStat – Pro enhances your home’s climate control with advanced features. By leveraging reverse cooling technology, specifically with air or ground source heat pump systems, the neoStat – Pro supports comfort cooling for year-round temperature management. Its precise control is supported by floor and air temperature probes and a built-in humidity sensor.*

For energy efficiency, it calculates the dew point and pauses cooling when needed to prevent condensation. This keeps your environment comfortable while conserving energy.

Providing subtle heating and comfort cooling control, the neoStat – Pro boosts comfort without sacrificing aesthetics or sustainability. It’s an ideal solution for modern, energy-conscious homes.

neoStat Pro Key Features

Standalone or Smart thermostat
A stylish mains-powered wall-mounted thermostat, or full Smart function control and data access through neoHub and the neoApp.
Wireless networking
neoStat Pro maintains an always-on link with other neo thermostats in the home. By networking each thermostat or zone together reliable control can be achieved in awkward conditions.
Remote sensors
Connects to both a remote air and remote floor sensor to monitor temperatures in the surrounding area.
Modern Design
Unobtrusive design to fit in with any home décor. Touch-sensitive keys provide a clean smooth interface, for a premium feel.

Reliable and Efficient Mesh Networking
Advanced mesh networking ensures stable communication across all connected devices, enhancing network range and stability while automatically routing data between neoStats.
Energy-saving optimum start
Calculates the heat-up time required for a warm home upon return. Those times are optimised throughout the year to save energy.
Hold temperature setting
Hold at a set temperature for a set length of time, after which the thermostat reverts to its programmed setting.
System compatibility
Compatible with Solar, Heat Pump and most Boiler Technologies.

Comfort cooling control
Designed to work seamlessly with heat pumps capable of comfort cooling, the neoStat – Pro focuses on maintaining optimal room temperature by monitoring the air temperature, floor temperature, and humidity levels. Using these inputs, the thermostat calculates the dew point and, when reached, it pauses demand to prevent condensation. This energy-efficient solution subtly lowers room temperatures by absorbing heat through floor pipes, ensuring a consistently comfortable environment, making it an ideal choice for well-insulated buildings. *Comfort Cooling Control Ready – This function will be fully available with an app update ready for Summer 2025

Functionality paired with neoHub

Switching Differential	This function allows you to increase the switching differential of the thermostat. The default is 1°C which means that with a set temperature of 20°C, the thermostat will switch the heating on at 19°C and off at 20°C. With a 2°C differential, the heating will switch on at 18°C and off at 20°C.
Frost Protect Temperature	This is the temperature maintained when the thermostat is in Frost Mode. The range is 05 – 17°C. The default is 12°C and is suitable for most applications.
Output Delay	To prevent rapid switching, an output delay can be entered. This can be set from 00 – 15 minutes. The default is 00 which means there is no delay.
Temperature Up/Down Limit	This function allows you to limit the use of the up and down temperature arrow keys. This limit is also applicable when the thermostat is locked and so allows you to give others limited control over the heating system.
Sensor Selection	The neoStat Pro automatically detects and uses remote probe connections. Once connected, you may change sensor configuration via the neoApp to meet requirements. You can select between air temperature only, floor temperature, or both. When you enable both sensors, the floor sensor is used as a floor limiting sensor and is designed to prevent the floor from overheating.
Dew Point	In cooling mode the thermostat will use the air, floor and humidity sensors to calculate the dew point temperature. Once the floor approaches dew point, the thermostat will stop cooling.
Floor Temp Limit	This function is available when the thermostat is set to use air and floor sensing options. You can set a floor limiting temperature between 20-45°C (28°C is the default setting). Note: This unit MUST NOT be used to control electric underfloor heating.
Comfort Cooling Ready	Allows the thermostat to actively cool when the system is in cooling mode.*Comfort Cooling Control Ready – Function will be fully available with an app update ready for Summer 2025
Optimum Start	Optimum start will delay the start up of the heating system to the latest possible moment to avoid unnecessary heating and ensure the building is warm at the programmed time. The thermostat uses the rate of change information to calculate how long the heating needs to raise the building temperature 1°C (with a rate of change of 20, the thermostat has calculated the heating needs 20 minutes to raise the building temperature 1°C) and starts the heating accordingly
Rate of Change	Number of minutes for 1°C temperature rise. The default setting is 20 minutes and can change on a daily basis. This setting cannot be changed and is for information only.
Program Mode	Non-Programmable, Weekday/Weekend (5/2),7 Day Programming or 24 Hour. The thermostat offers three programming modes and the option of configuring it to work as a non-programmable thermostat. Weekday/ Weekend – allows you to program 4 comfort levels for the weekday and 4 different comfort levels for the weekend. 7 Day Program Mode – Each day has 4 comfort levels that can be programmed independently. 24 Hour Mode – All days are programmed the same and repeat continuously.
Temperature Format	This function allows you to select between °C and °F.
