FAQs

How do I set a hot water schedule?

Navigate to the programming menu using the device buttons. Select your desired programming mode (5/2 day, 7-day, or 24-hour) and set the on/off times for each period as required.

Can I control my central heating with this device?

The neoStat-HW is specifically designed for hot water control. While it has changeover contacts, it is intended for managing the hot water circuit independently or in conjunction with a separate heating programmer.

What is the holiday function used for?

The holiday function allows you to set the system to an energy-saving mode (e.g., maintaining a lower temperature or turning off) for a specified period when you are away from home. It can be programmed to resume normal operation just before your return.

How do I activate the key code facility?

Access the settings menu and look for the 'Key Code' or 'Lock' option. Follow the on-screen prompts to enable the facility and set your desired code.

What are the dimensions of the neoStat-HW?

The dimensions are 85mm x 85mm x 13mm.

Does this require a specific type of back box?

Yes, for flush mounting, it requires a back box with a minimum depth of 35mm.

What is the IP rating?

The IP rating is IP20, which means it is protected against solid objects larger than 12.5mm and offers no protection against water.

Troubleshooting

Device does not power on

Check that the main power supply is switched on and that all wiring connections are secure and correct according to the installation manual.

Hot water is not heating
