AMBIENTE PRT-N-E 43510 (01) PDF Document

A programmable room thermostat like the AMBIENTE PRT-N-E 43510 is both a programmer and a room thermostat. A programmer allows you to set “On” and “Off” periods to suit your 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.

This allows you to choose what times you want the heating to be on and what temperature it should reach while it is on. You can 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 the 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 the AMBIENTE PRT-N-E 43510 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 AMBIENTE PRT-N-E 43510 for optimal savings 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, for example 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.

This thermostat is designed to be flush mounted and requires a back box of 35mm (minimum depth) to be sunk into the wall prior to installation.

Do:

Mount the thermostat at eye level.
