OJ.D.OCC2.GB.02.A
Subject to alterations
CE Marking:
The thermostat meets the requirements of the following
standards:
EMC directive: Low voltage directive:
EN50081-1 EN60730-1
EN50082-1 EN60730-2-9
MOUNTING
Mounting of the thermostat:
Mounting of floor sensor:
The floor sensor is used for comfort heating of the floor. The
sensor is mounted in conduit for replacement purposes. The
conduit is placed between heating cables and is ended
towards the floor surface.
If required, the sensor cable may be extended up to 100 m with
standard installation cable.
Mounting of room sensor:
The room sensor is used for room heating. Thermostat with
internal sensor is mounted approx. 1.6 m above the floor.
Draught, direct sunlight or any other direct heating outlet must
be avoided. If it is not possible to mount the thermostat in the
correct position, remote room sensor type ETF-944/99-H is
recommended. A thermostat incl. floor sensor is used, but the
room sensor is connected instead of a floor sensor.

Manual mode:
The scheduled event program can be cancelled e.g. during
holidays, instead the temperature can be adjusted to e.g. 5˚C
for frost protection. The new setpoint is valid until the manual
mode is cancelled.
Monitoring of energy consumption:
Total switch-on time in percentage can be read-out within the
latest 2 days, 30 days or 365 days. In this way the heat
consumption can be controlled.

Backup function:
All settings and the clock are maintained in case the thermostat
is switched off on the built-in interrupter. In case the main
power supply is interrupted for more than 50 hours the current
time and date must be reset.
Read-out of sensor temperature:
The actual temperature of the floor sensor can be read-out.
