Special Features
Description
Optimisation (optimal
start, optimal stop and
delayed start)
Optimal Start: learns how long it takes your system to reach the programmed temperature.
It turns on the heating system earlier to make sure it’s comfortable at the scheduled time.
Optimal Stop: Saves energy and money by switching off a little bit earlier than the normal
programmed time. If the home is up to temperature, it will not notice the effect on the
temperature, but will show a difference in the fuel bill.
Delayed start: Saves energy by slightly delaying the start of heating depending on the
difference between the scheduled temperature and the actual room temperature
Clock setting
Change display format (default 24hr) and adjust time and date.

Low Load Control
If the Receiver box is connected to an OpenTherm appliance this setting is used in the

switches from modulating control to low/off control.
Temperature Offset
If the Thermostat is located in a hot/cold location and cannot be moved because of wiring
then the measured/ displayed temperature can be adjusted by +/- 1,5
o
C. This feature is
useful if the homeowner wants the reading to match another appliance temperature
display.
Binding
Menu to bind the Thermostat and the Receiver box, test the RF signal strength of the radio
communication and to clear an existing binding.
Reset
