Thermostats Types RT 101, RT 102
Fig. 1 and 2
Max. ambient temperature: 70 °C
Max. temperature of sensor : 300 °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
Fig. 4
A. Range setting
B. Differential obtained
C. Differential setting
The thermostat should be set according to
the function - make or break - to take place
on a drop in temperature (range setting).
Setting is done 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 nomogram in Fig. 4. The
maximum operating temperature is thus
the sum of the temperature setting and
the differential.
Example
It is desired to control the temperature of
an oil-fired central heating boiler by the
use of an RT 101.
Maximum temperature: 76 °C
Minimum temperature: 70 °C
Differential: 76 °C - 70 °C = 6 °C
1. Connect the oil burner to terminals 2-1
of the thermostat
2. Set the thermostate for 70 °C by rotating
the knob (5)
3. Set the differential adjusting nut (19)
between figures 3 and 4, as indicated by
the nomogram in fig. 4.

Termostater Type RT 101, RT 102
Fig. 1 og 2
Omgivelses temperatur: 70 °C
Max. følertemperatur: 300 °C
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
håndknappen (5) under samtidig aflæsning
af hovedskalaen (9).
Differensen indstilles med differensrullen
(19) efter nomogrammet i figur 4. Højeste
funktionstemperatur er således lig sum-
men af indstillingstemperatur og differens.
