Heatmiser Thermostat Installation

The Heatmiser Neo System

Heatmiser Neo is Wilsons' specialist heating controls platform. The system is modular — each thermostat communicates wirelessly to the neoHub, which provides app control and integrates with Control4.

neoStat V2 / V3 — Wiring

The neoStat V2 and V3 use identical terminal wiring:

The neoStat replaces a conventional room thermostat. It requires a permanent live, a neutral, and a switched live output to switch heating demand.

On a combi boiler: Connect SL to the boiler's RT/TH terminals.

On an S-plan system: Connect SL to the live input of the relevant zone valve motor.

On an ASHP system: Connect SL to the heat pump's demand input contacts.

The neoStat fits a standard single gang back box — 25mm minimum depth recommended.

neoStat — Pairing to neoHub

After wiring and powering the neoStat:

1. On the neoHub, press the pair button on the rear
2. On the neoStat — Settings → Network → Pair
3. The stat searches for and connects to the neoHub — up to 60 seconds
4. Once paired, the stat appears in the Heatmiser Neo app under the hub
5. Assign the zone name in the app (e.g. "Lounge", "Master Bedroom")

If pairing fails: confirm the neoStat is within wireless range of the neoHub (max ~100m open air, less through walls). Move the hub temporarily closer to pair if needed.

neoAir — Wireless Thermostat

The neoAir is battery-powered and communicates wirelessly to either:

• UH8-RF wiring centre — for UFH zones (no separate receiver needed)
• neoAir receiver — wired in place of the old thermostat; provides the switched live output

Pairing neoAir to UH8-RF:

1. On the UH8-RF, select the zone to pair and press the zone button until the LED flashes
2. On the neoAir — Settings → Pair
3. Connection confirmed by LED on UH8-RF
4. Assign the zone name in the Heatmiser app

Battery life: typically 1–2 years on 3× AA alkaline batteries.

neoHub — Installation & Setup

The neoHub connects to the customer's router via ethernet cable — Wi-Fi is not supported. Place it within ethernet cable reach of the router and within wireless range of all stats.

Setup:

1. Connect neoHub to router via ethernet
2. Power the neoHub via the supplied USB power supply
3. Download the Heatmiser Neo app (iOS or Android)
4. In the app — Add Hub → scan the QR code on the underside of the hub
5. Wait for the hub to come online (up to 2 minutes — solid LED)
6. All paired neoStats and neoAirs appear automatically
7. Name each zone and configure heating schedules

Customer handover — share hub access:

1. In the app — Settings → Share Hub → Invite User
2. Enter the customer's email address
3. Customer installs the Heatmiser Neo app and accepts the invite
4. They can then view temperatures, adjust targets, and set schedules from anywhere
