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

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.

Danfoss RT 103 Thermostat Installation Guide Overview

Summary of Contents

• Page 1: Installation guide Thermostat Types RT 103, RT 140, RT 141 To ensure IP66 or IP54 grade of RT enclosure, it is necessary to assemble the cable gland as shown in fig. 3. If the cable gland is not used with a cable, a metal blinding should also be assembled. Ambient temperature: -50 °C – 70 °C Maximum sensor temperature for RT 103 is 100 °C. The thermostat is set by rotating the knob (5), while reading the main scale (9). The differential is set by the differential adjusting nut (19) according to the nomogram in fig. 4. Maximum discharge temperature is 32 °C and minimum discharge temperature is 30 °C. The highest function temperature is the sum of the setting temperature and the differential. Connect the heater to terminals 1-2 of the thermostat.
