Heatmiser neoStat v3 Programmable Thermostat - White

The Heatmiser neoStat v3 Programmable Thermostat - White is a 230V smart room thermostat designed as a direct replacement for neoStat v2 and other 3‑wire thermostats, offering app control (via neoHub), multiple time/temperature programs, and a clean, flush-mounted white finish.

Product Description

neoStat v3 combines a slimline backlit display with illuminated touch keys and can be configured either as a programmable room thermostat or as a simple timer. When paired with the neoHub, it becomes part of the Heatmiser neo smart control ecosystem, enabling remote control, scheduling and integration with leading home automation platforms.

Key Features

• V2 replacement: Fully compatible form factor and wiring with neoStat v2 for straightforward upgrades.
• Programmable control: Multiple operating modes (7‑day, 5/2‑day, all days same/different) with up to 4 comfort levels per day (expandable to 6 with neoHub G2).
• Smart operation: Optimum Start, Temperature Hold and Holiday modes improve comfort and energy efficiency.
• Mesh connectivity: Communicates with neoHub via wireless Mesh for improved range and reliability across the property.
• Dual function: Can be set as a thermostat or as a timer to control heating zones, towel rails or lighting circuits.
• User-friendly design: White backlit display with proximity activation and illuminated soft‑touch keys.

Technical Details

• Power supply: 230V AC, 50Hz.
• Switching: Volt-free relay output for boiler/zone valve control (suitable for water-based heating).
• Sensor options: Built‑in air sensor; compatible with 10K, 12K and 15K NTC floor probes for underfloor applications.
• Temperature control: 0.5°C setpoint increments with frost protection and adjustable setpoint limits.
• Programming interval: 5‑minute time steps for fine scheduling control.
• Display: White backlight, auto‑off after around 30 seconds to reduce power consumption.
• Smart integration: Full app control and automation features when used with neoHub G2 (not compatible with neoHub G1).

System & Application Notes

• Typical use: Room thermostat for water-based radiator or underfloor heating zones; also suitable as a timer for auxiliary loads.
• Wiring: Designed to replace existing 3‑wire thermostats (live, switched live, neutral) without rewiring in most cases.
• Smart control: Use with neoHub and neoApp for multi‑zone control, remote access and integration with voice assistants and smart home platforms.
• Upgrade path: Recommended replacement for older 230V Heatmiser models and neoStat v2 where enhanced Mesh performance and v3 features are desired.
