Thermal control algorithm and smart backlight
Thermal differential algorithm
Proportional-Integral algorithm
For systems with signifi cant variations in the outdoor temperature.
Optimise consumption and reduce boiler ignition times by setting a minimum boiler
ignition time as part of a cycle.
There are 3 pre-confi gured programmes and 1 manual programme available for setting
parameters.

For systems with diff erent thermal inertias.
The thermal diff erential can be adjusted
between 0.1°C and 1°C.
