Maximum sensor temperature:
RT 103: 100 °C
RT 140: 240 °C
RT 141: 250 °C
INSTALLATION
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 external reset) grade of RT enclosure
it is necessary to assemble this gland as
shown in the fig. 3. If this gland is not used
with a cable, a metal blinding should be
also assembled.
SETTING

The thermostat is set by rotating the knob
(5), at the same time reading the main
scale (9).
The differential is set by rotating the

differential adjusting nut (19) to the value
indicated by the use of the nomogram in
fig. 4. The maximum operating pressure is
thus the sum of the setting temperature
and the differential.
Example
It is desired to control an air heater by the
use of an RT 103.
Maximum discharge temperature: 32 °C
Minimum discharge temperature: 30 °C
Differential: 32 °C - 30 °C = 2 °C
1. Connect the heater to terminals 1-2 of
the thermostate
2. Set the thermostate for 30 °C by
rotating the knob (5)
3. Set the differential adjusting nut (19) at
the figure 4 which is found by reading
the nomogram for RT 103 in fig. 4.

INSTALLATION
Et sæt Pg13,5 kabelforskruning er vedlagt
produktet i en separat pose. For at sikre
kapslingsgrad IP66 (enheder med automa-
tisk reset) eller IP54 (enheder med ekstern
DANSK RESET) er det nødvendigt at mon-
tere denne kabelforskruning som vist i fig. 3.
Hvis denne kabelforskruning ikke bruges
sammen med et kabel, bør der monteres
en blindprop (metal skive).
INDSTILLING

A. Områdeindstilling
B. Opnået differens
C. Differensindstilling
Termostaten indstilles efter den funktion
- slutte eller bryde - som skal ske ved
faldende temperatur (områdeindstilling).
Selve indstillingen udføres med håndknap-
pen (5) under samtidig aflæsning af
hovedskalaen (9).
Differensen indstilles med differensrullen
(19) efter nomogrammet i figur 4. Højeste
funktionstemperatur er således lig summen
af indstillingstemperatur og differens.
Eksempel
En varmluftovn ønskes styret af en RT 103.
Max. afgangstemperatur: 32 °C
