8.8 Room temperature offset
If no remote control is installed in the living area, the room temperature
compensation (see Chapter 8.6 "Maximum room temperature compensation"
page 39) cannot be used. The room temperature values set on the controls then
simply provide a specification for calculating the boiler setpoint temperature.
If the room temperature shown on the display differs from the room temperature
measured with a thermometer mounted nearby, the values can be adjusted
using "OFFSET".
Do not take the measurements while the system is heating up, e.g. after the
night setback, but only after it had time to stabilize for several hours.
The adjustment causes a parallel shift in the heating curve.
The factory setting is:

Matching temperature values
Offset: 0°F (0°C)
for example: Displayed room temperature 72°F (22°C)
Measured room temperature 75°F (24°C)
Offset -3°F (-2°C)

"PERIM HTG" or "FLOOR HTG" appears.
Turn the dial until "OFFSET" is shown.

Hold down the "Display" key and turn the dial until the required value appears
(in this case "-3°F").
Release "Display" to store your input.
Press "ENTER" to return to the next higher level.
