Heatmiser neoStat-HC – Smart Fan Coil Thermostat
What is a Programmable Room Thermostat?
A programmable room thermostat is both a programmer and a room thermostat. A programmer allows you to set “On” and “Off” periods to suit your own lifestyle. A room thermostat works by sensing the air temperature, switching on the heating when the air temperature falls below the thermostat setting, and switching it off once this set temperature has been reached. So a programmable room thermostat lets you choose what times you want the heating to be on, and what temperature it should reach while it is on. It wil allow you to select different temperatures in your home at different times of the day (and days of the week) to meet your particular needs and preferences. Setting a programmable room thermostat to a higher temperature will not make the room heat up any faster. How quickly the room heats up depends on the design and size of the heating system. Similarly reducing the temperature setting does not affect how quickly the room cools down. Setting a programmable room thermostat to a lower temperature will result in the room being controlled at a lower temperature, and saves energy. The way to set and use your programmable room thermostat is to find the lowest temperature settings that you are comfortable with at the different times you have chosen, and then leave it alone to do its job. The best way to do this is to set the room thermostat to a low temperature – say 18°C , and then turn it up by 1°C each day until you are comfortable with the temperature. You won’t have to adjust the thermostat further. Any adjustment above this setting will waste energy and cost you more money. You are able to temporarily adjust the heating program by overriding or using the temperature hold feature. These features are explained further on pages 17 and 18 of this manual. Programmable room thermostats need a free flow of air to sense the temperature, so they must not be covered by curtains or blocked by furniture. Nearby electric fires, televisions, wall or table lamps may also prevent the thermostat from working properly.
Installation Procedure
Do
- Mount the thermostat at eye level.
- Read the instructions fully so you get the best from our product.
Don’t
- Do not install near to a direct heat source as this will affect functionality. Do not push hard on the LCD screen as this may cause irreparable damage.
The neoStat V2 is designed to be flush mounted and requires a back box of 35mm (minimum depth) to be sunk into the wall prior to installation.
- Step 1 Using a small screwdriver, slightly loosen the screw from the bottom face of the thermostat. Then carefully separate the front half from the back plate.
- Step 2 Place the thermostat front somewhere safe. Terminate the thermostat as shown in the diagrams on pages 28-31 of this booklet. Note: For time clock wiring connections, terminate as shown on page 38.
- Step 3 Screw the thermostat back plate securely into the back box.
- Step 4 Clip the front of the thermostat onto the back plate, securing it in place with the retaining screw.

What is a Mesh Network.
NeoStats work using a mesh network, meaning neoStats have the ability to send & receive signals via other thermostats on the network. This signal is relayed from one thermostat to another until it reaches its destination. This communication method extends the communication range whilst offering increased network stability when compared with standard RF thermostats. The Mesh symbol is shown when the device is communicating with the neoHub, if the mesh symbol disappears this indicates connection to the neoHub has been lost.
Approach Sensor
The neoStat V2 uses proximity to detect when you are about to use the touch keys. As you approach the neoStat V2, the touch keys and backlight will light up. This can be useful if you need to adjust the set temp or timer in a dark room.

- Feature 01 – Pairing To neoHub: This function is used to connect the thermostat to the neoHub.
- Feature 02 – 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 of20°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.
- Feature 03 – Frost Protect Temperature: This is the temperature maintained when the thermostat is in Frost Mode. The range is 07 – 17°C. The default is 12°C and is suitable for most applications.
- Feature 04 – 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.
- Feature 05 – 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.
- Feature 06 – Sensor Selection: On this neoStat, you can select which sensor should be used. 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.
- Feature 07 – Floor Temp Limit: This function is available when mode 06 is set to 03 or 04.You can set a floor limiting temperature between 20-45°C (28°C is the default setting).
Note: Air Sensor only MUST NOT be used to control electric under-floor heating. Floor Sensor or Both should be used. - Feature 08 – 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.
- Feature 09 – Rate of Change: Number of minutes for 1°C temperature rise.
- Feature 10 – Not used on this model.
- Feature 11 – Not used on this model.
- Feature 12 – 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.
- Feature 13 – Temperature Format: This function allows you to select between °C and °F.
