5. OPTIMUM START

Optimum start is an intelligent system controlling the heating process. It involves constant monitoring of the heating system efficiency and using
the information to activate the heating in advance in order to reach the pre-set temperatures.
The system requires no user intervention. It precisely reacts to any changes that affect the efficiency of the heating system. If, for example, some
changes have been introduced to the heating system and the house heats up faster than before, the Optimum start system will recognize the
changes at the next pre-programmed temperature change and in the next cycle the heating system activation will be adequately delayed,
reducing the time needed to reach the desired temperature.

A – pre-programmed change from economical temperature to comfort temperature.
Activating this function means that at the time of pre-programmed change of the pre-set temperature determined by the schedule, the current
room temperature will be close to the desired value.
!
NOTE
Optimum start is available only in heating mode.

6. HYSTERESIS

Room temperature hysteresis defines the tolerance of the room tempearture in order to prevent undesired oscillation in case of small tempera-
ture fluctuations (within the range 0,1 to minus 5°C).
Example:
Desired room temperature: 20°C
This means that the room temperature will operate within 19,8°C (starts heating) to 20,2°C (stops heating).

7. CALIBRATION

Room sensor can be calibrated if the measured room temperature displayed differs from the actual measured temperature (best to use an infra-
red thermometer). Calibration setting range is from -10°C to +10°C with the accuracy of 0,1°C.
Choose "Calibration" using ▼ – pres MENU. Set "Degrees" with ▼ or ▲ – press MENU. Press MENU to "CONFIRM" or choose "CANCEL"
with ▲ – press MENU.

8. ACTUATORS

Here you have the possibility to add and control up to 6 Roth Softline wireless Radiator actuators to the zone.
