Application

EFET 160 is an electronic thermostat designed for regulating heat and

cold from -10˚C to +50˚C.

EFET 160 is moisture proof (IP 44) so it can be used in moist rooms
and outdoors.

EFET 160 has a built-in 2-pole switch, so an external switch is not
necessary.

EFET 160 is supplied with a NTC sensor of 2.5 m cable. The sensing cable
can be extended up to 50 m with 1.5 mm² installation cable without
affecting the accuracy of the thermostat. However, the cable must not
be placed parallel to high voltage cables as undesirable signals may be
induced. The installation must be permanent. The thermostat must be
connected by an authorized electrician.

Installation

1. Before opening the thermostat housing set adjustment button to
minimum temperature, viz. -10˚C.

2. When installing in bathrooms etc., the minimum distance to water
installations must be observed and must comply with current regula­tions for electric installations.

3. The stamped punchings for diaphragm nipple are removed with a
screwdriver and a hammer.

4. The thermostat is mounted vertically on a wall. The screw holes must
be sealed with the enclosed plugs.

5. If the sensor is to be built in or exposed to pressure it should be
placed in an installation pipe.

6. Installation of thermostat see diagram. Choose function (heating/
cooling).

7. After closing the thermostat housing, check that adjustment button
can be adjusted within full temperature range, i.e. from -10˚C to
+50˚C.

Accessories for EFET 160:

- fittings for mounting on pipes,

- outdoor sensor for use with the thermostat.

Mounting the outdoor sensor:

1. Knock pellets out of the thermostat and sensor.

2. Mount the black connection nipple in the sensor hole. Then twist the
connection nipple into the thermostat hole. Turn the outdoor sensor
until the three small locks click.

3. Connect the NTC sensor to the NTC input with a soft mounting cable,
e.g. Ø 0.25 mm2.

4. Fasten the outdoor sensor and thermostat seperately with screws or
clips.
