Temperature Balancing (Wall Compensation); Start Optimisation; External Input - Viessmann VITOTROL 100 OT Installation & Service Instructions Manual

Temperature Balancing (Wall Compensation)

If the controller is mounted in an unfavourable installation location, the room temperature displayed
may deviate from the actual room temperature. The temperature deviation can be adjusted with a
correction value.
1. Use <--/--> to select "WALL COMP"
2. OK to confirm
3. Use +/- or the rotary selector to set the required corrected temperature.
4. OK to confirm

Start Optimisation

Only for room temperature-dependent mode: The controller uses the difference between the set
and actual room temperatures to determine how far in advance to set the central heating start time.
This ensures that the set room temperature is achieved at the beginning of the set time phase.
Example: With a temperature differential of 6 K and a setting of 5 min/K, central heating starts 30
minutes earlier.
Factory setting 00 (no start optimisation)
1. Use <--/--> to select "OPTIMISE"
2. OK to confirm
3. Use +/- or the rotary selector to set the required optimisation value in min/K
4. OK to confirm

External Input

1. Use <--/--> to select "EXT INPUT"
2. OK to confirm
3. Use +/- or the rotary selector to set the required function. See the table below
4. Once the function is selected, press OK to confirm
