7.2 Preliminary work for
incremental heating test
Carry out an incremental heating test to check
the correction function of the surface tempera-
ture regulation system.
On delivery, the sensor unit is at
position 3.

NOTICE
Damage to the screed as a re
sult of incorrect temperatures
f Carry out the incremental heating
test of concrete and calcium sul-
phate screed in accordance with
DIN EN 1264-4.
f Observe the instructions of the
screed manufacturer.
f Adapt the flow temperature to the
surface temperature regulation
system.
f Do not exceed the screed temper-
ature specified as per DIN 1264-4
near the heating pipes.
Apply heating screed complying with standards
after plastering.
Start the incremental heating test at the earli-
est:
• 21 days after laying of concrete screed
• 7 days after laying of calcium sulphate
screed
7.3 Incremental heating test
Proceed as follows during the incremental
heating test:
1. Remove the protection cover.
2. Set the sensor unit to position "5".
3. Refit the protection cover.
Control the flow temperature via
the heat generator control.
4. Start with a flow temperature between
20°C and 25°C for at least 3 days.
5. Then heat at the maximum design flow
temperature for at least 4 days.
7.4 Fitting of the handwheel and
cover
1. After having completed all building work,
remove the protection cover of the Unibox
RTL.
2. Set the sensor unit to position "3" when
