Simple temperature scheduling and levels of automated control offer a level of intuitive usability expected from today’s technology, with a lockable keypad and an Optimisation option.
Optimisation has three functions:
- Optimum Start learns how long the house takes to heat up and turns the heating on earlier.
- Optimum Stop is the same but in reverse – if the house is at a temperature as the programmed off time is approaching it will turn off a little earlier.
- Delayed Start measures current room temperature and desired room temperature and delays the start-up.
The T4 is easy to install and compatible with all boiler applications, making it the ideal replacement for an existing thermostat.
