thus the sum of the setting temperature  
and the differential.  
INSTALLATION  
ENGLISH  
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).  
Thermostats Types RT 103, RT 140, RT 141  
Fig. 1, 2 and 4  
Ambient temperature: -50 °C – 70 °C  
Maximum sensor temperature:  
RT 103: 100 °C  
Example  
RT 140: 240 °C  
RT 141: 250 °C  
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

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.  
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.  
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.
