Technical data
Mechanical differential (DIFF)
RT 8L and RT 16L: 1.5K (2.7 °F)
RT 14L: 1.5K (2.7 °F) / 0.7K (1.3 °F)
min./max. range
RT 101L: 2.5K (4.8 °F) / 3.5K (6.7 °F)
min./max. range
Benyt monteringshullerne pos. 25.
Termostaten monteres bedst med
håndknappen 5 opad.
Termostathuset og kapillarrøret kan
anbringes koldere eller varmere end føleren.
For RT 8L og RT 14L kan den cylindriske føler
fastgøres til væg ved hjælp af en følerholder
26 eller monteres i brinetank ved hjælp af et
dykrør 30 eller en kapillar-rørspakdåse 31.
Se fig. 1.
Example: RT 8L
Required temperature: -2.5 °C (27.5 °F).
Required neutral zone (NZ): 3 °C (5.5 °F).
The thermostat is set for -2.5 °C (27.5 °F) by
rotating the knob 5.
RT 140L: 1.8K (3.2 °F) / 2K (3.8 °F)
min./max. range
As it can be seen from the diagram, the re-
quired dead zone of 3 °C (5.5° F) is obtained
by setting the setting disc 40 at 2.4.
The make and break temperatures of the
switch (see fig. 5) are then – with the differen-
tial fixed at 1 °C (1.8 °F):
Maximum ambient temperature
RT 8L, RT 14L, RT 101L, RT 140L:
-50 °C (-58 °F) − 70 °C (160 °F)
RT 16L: 50 °C (120 °F)
Skal kapillarrøret føres gennem en væg, gøres
dette lettest via et indmuret rør, der lukkes
med gummipropper.
Make temperature of contacts
1–4 = -2.5 °C + 1 °C = -1.5 °C (27.5 °F + 1.8 °F =
29.3 °F).

RT 140L: 240 °C (465 °F)
Make temperature of contacts
1-2 = -1.5 °C - 3 °C = -4.5 °C (29.3 °F - 5.5 °F =
23.8 °F).
Min. temperature variation rate
< 1K/15 minutes.
Indstilling
Break temperature of contacts
1-2 = -4.5 °C + 1 °C = -3.5 °C (23.8 °F + 1.8 °F =
25.6 °F).
Den ønskede temperatur (= brydetempera-
turen for kontakterne 2-3) indstilles ved hjælp
af håndknappen 5. Indstillingen aflæses på
områdeskalaen 9. Den ønskede neutralzone
(NZ) opsøges i diagrammet.
På diagrammets nederste skala aflæses den
position, neutralzonerullen 40 skal indstilles
på.

Rating
See switch cover or fig. 10.
The marking, e.g. 10 (4) A, 400 V ~ AC means
that max. connection current is 10 A ohmic
and 4 A inductive at 400 V ~.

Fast differens (DIFF)
RT 8L og RT 16L: 1.5K
Eksempel: RT 8L
Ønsket temperatur: -2.5 °C (27.5 °F).
Ønsket neutralzone (NZ): 3 °C (5.5 °F).
The max. starting current on motor cutin (L.R.)
may be up to seven times the inductive load.
RT 14L:
1.5K/0.7K i min./maks. område
RT101L: 2.5K/3.5K i min./maks. område
RT 140L: 1.8K/2K i min./maks. område
Med håndknappen 5 indstilles termostaten på
-2.5 °C (27.5 °F) Som det ses af diagrammet,
opnås den ønskede neutralzone på
3 °C (5.5° F) ved at indstille neutralzonerullen
40 på positionen 2.4.

Fitting
A set of Pg13.5 cable gland is attached to the
RT in a separate bag. To ensure IP66 (units
with automatic reset) or IP54 (units with ex-
ternal reset) grade of RT enclosure it is neces-
sary to assemble this gland as shown in the
fig. 10. If this gland is not used with a cable, a
metal blinding should be also assembled.

Use the mounting holes item 25.
The thermostat is fitted best with the knob 5
facing upwards.
The thermostat housing and the capillary
tube can be placed colder or warmer than the
bulb.
In the case of RT 8L and RT14L, the cylindrical
bulb can be fixed to a wall by using a bulb
holder 26 or it can be fitted in a brine tank by
means of a bulb pocket 30 or in capillary tube
gland 31. See fig. 1.
Brydetemperatur for kontakterne
1-4 = indstillet temperatur: –2.5°C (27.5 °F).
RT 101L: 300 °C (570 °F)
RT 140L: 240 °C (465 °F)
Sluttetemperatur for kontakterne
1-2 = –1.5°C - 3°C = -4.5°C 29.3 °F - 5.5 °F =
23.8 °F).
Min. temperaturændringshastighed
< 1K/15 minutter.
Brydetemperatur for kontakterne
1-2 = -4.5 °C + 1 °C = -3.5°C (23.8 °F + 1.8 °F =
25.6 °F).
Tæthedsgrad
IP 66 iht. IEC 529.
If the capillary tube is to be passed through
a wall, it can be done most easily by using a
grouted-in pipe closed by rubber plugs.
Kontaktbelastning
Se kontaktdækslet eller fig. 10.
Mærkningen, f.eks. 10 (4) A, 400 V ~ AC
angiver, at der maks. må tilsluttes 10 A ohmsk
og i A induktiv belastning ved 400 V~.
Den maksimale startstrøm ved indkobling
af motor (L.R.) må være op til syv gange den
induktive belastning.
Electrical connection
Cable connection Pg 13.5.
Cable diameter 6 − 14 mm.
The screwed cable entry shown in fig. 11 is
used with rigid cable conduit. Earth connec-
tion to earth terminal 38.
Montering
Et sæt Pg13,5 kabelforskruning er vedlagt
produktet i en separat pose. For at sikre
kapslingsgrad IP66 (enheder med automatisk
reset) eller IP54 (enheder med ekstern
Setting
The required temperature (= break
temperature of contacts 2-3) is set by rotating
