Introduction
Back
The NGT thermostat can switch your underfloor heating system on
and off at predetermined times throughout the week. Each day of
the week is split up into four separate periods, each of which can
have a different target temperature. This allows you to lower the
temperature in rooms that are unoccupied at different times reducing your energy usage without reducing your comfort.
Your NGT thermostat comes ready programmed with a default
schedule which is suitable for most homes. If you do not change the
settings your thermostat will follow the default schedule.
Your thermostat also features an adaptive function that learns
how long the floor takes to heat up and cool down as the seasons
change and takes this into account when turning the heating on
and off. This ensures the room is always up to temperature at the
desired time. The adaptive functions fuzzy logic takes three days
to learn the heat characteristics of the room before it operates efficiently.
In various parts of the menus and submenus you will find the Back
menu item.
