12.4 Calibration of the thermostat
RTL (sensor unit)
The thermostat RTL (sensor unit) is factory cal-
ibrated. A perfect function of the Unibox RTL is
only guaranteed if it is correctly calibrated.
Should you have changed the calibration, pro-
ceed as follows to recalibrate the thermostat
(see Illust. 21 on page 39):
• Turn the sensor unit to position "3" (instal-
lation position; see Illust. 13 on page 34).
The figure "3" must be in line with the
indicator line.
