7.2 Preliminary work for

incremental heating test

Carry out an incremental heating test to check
the correction function of the surface heating
system.
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 heating 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. Open the valve fully by turning the white
protection cap about one turn.
Control the flow temperature via
the heat generator control.
2. Start with a flow temperature between
20°C and 25°C for at least 3 days.
3. Then heat at the maximum design flow
temperature for at least 4 days.
7.4 Installation of the thermostat
with remote control
1. After having completed all building work,
remove the protection cover of the "Unibox
T vario".
2. Remove the protection cap.
3. Screw the control piston (see Illust. 8 on
page 25 (1)) onto the valve. Direct the
capillary downwards.
The capillary must not be kinked.
