ETO2
Outdoor sensor ETF, fig. 2:
For use in conjunction with gutter sensor ETOR. Can
also be used separately for the detection of
temperature alone. The sensor should be mounted
on the wall under the eaves on the north side of the
building.
Sensor cables:
ETOG and ETOR are supplied with 10 m cable,
which can be extended up to approx. 200 m using
standard installation cable: 6x1.5 mm² for ETOG and
4x1.5 mm² for ETOR (total resistance must not
exceed 10 ohm). The ETF cable can be up to
approx. 50 m in length. Sensor cables must be
installed in accordance with current regulations.
They must never be installed parallel to power
cables as electrical interference may distort the
sensor signal.
Thermostat installation, fig. 6
The unit should be DIN-rail mounted in an approved
panel or wall-mounted in a specially designed and
approved metal box (accessory). Connect supply
voltage to terminals PE, N and L. All electrical and
mechanical installation must be performed in
accordance with applicable local regulations.
Setup:
Two sensors can be connected to the thermostat,
e.g. two ETOG in the same zone, one ETOG in each
of two zones (2-zone control), or two ETOR/ETF in
gutter or downpipe.
• 1-zone electric heating control with ETOG,
output relays 1, 2 and 3 (fig. 3):
Connect 2 (1) ETOG sensors to terminals 11-20.
Connect heating cable to output relays 1, 2 and 3
using terminals 3-8.
