Understanding the Programmable Room Thermostat
The neoStat Touch-e combines a heating programmer with a temperature controller.
The thermostat measures temperature and activates heating when the temperature falls below the selected target. Once the required temperature is reached, the thermostat stops requesting heat.
The programming function allows different temperature settings to be applied at selected times throughout the day.
How Temperature Settings Affect Heating
Increasing the target temperature does not cause a heating system to warm a room faster.
The time required to heat a room depends on the design and size of the heating system.
A higher temperature setting causes the heating system to continue operating until the higher temperature is reached.
Similarly, lowering the target temperature does not make a room cool faster. It changes the temperature that the thermostat maintains.
Selecting a Comfortable Temperature
A suitable way to establish a comfortable heating temperature is to begin with a lower setting, such as 18°C, and increase it gradually by 1°C each day until the required comfort level is reached.
Once a comfortable temperature has been established, the thermostat can maintain it according to the programmed schedule.
Avoiding unnecessarily high temperature settings can reduce heating energy consumption.
Thermostat Position and Temperature Accuracy
Room thermostats require unrestricted airflow to measure temperature accurately.
The thermostat should not be covered with curtains or obstructed by furniture.
Nearby electrical heaters, televisions, and lamps can also affect temperature measurement and interfere with normal operation.
