General safety instructions
1 General safety instructions
For your own safety, follow these instructions concerning the mounting, start up, and opera-
tion of the thermostat:
− The thermostat is to be mounted, started up or operated only by trained and experienced
personnel familiar with the product.
According to these mounting and operating instructions, trained personnel refers to
individuals who are able to judge the work they are assigned to and recognize possible
dangers due to their specialized training, their knowledge and experience as well as
their knowledge of the applicable standards.
− Upon installation of the electric cables and connecting the device, observe the VDE
regulations as well as the regulations of your local power supplier. Make sure all
electrical connections are installed only by trained and experienced personnel.
To avoid damage to any equipment, the following also applies:
− Proper shipping and storage are assumed.
Note
The device with a CE marking fullls the requirements of the Directives 2014/30/EU and
2014/30/EU, 2014/35/EU and 2011/65/EU.
The EU declarations of conformity are included in the Appendix of these instructions.

Design and principle of operation
2 Design and principle of oper-
ation
The thermostats are equipped with a
changeover contact. When the thermostat is
triggered, the connection between connections 1 and 2 are interrupted and the connections 1 and 4 are connected (see Fig.5
on page14).
Safety temperature monitor (STM)
A snap-action switch in the STM is triggered
when the temperature at the temperature
sensor rises above the adjusted set point.
When the temperature falls below the set
point by approximately 8K, the switch re-
turns to its original position.
The contact opens or closes when the temperature at the temperature sensor falls below –20°C. It automatically closes or opens
again when the temperature at the temperature sensor rises above –20°C.
The STM is triggered when the capillary tube
breaks.
Temperature regulator (TR)
The snap-action switch is triggered when the
temperature at the temperature sensor rises
above the adjusted set point. When the temperature falls below the set point by approximately 4K, the switch returns to its original
position.
Safety temperature limiter (STL)
The snap-action switch is triggered and
locked when the temperature at the temperature sensor rises above the adjusted set
point. When the temperature falls below the
set point by approximately 10%, the
snap-action switch can be unlocked manual-
ly.
The contact opens or closes when the temperature at the temperature sensor falls below –20°C. It automatically closes or opens
again when the temperature at the temperature sensor rises above –20°C.
The contact opens or closes when the system
fails. It is not possible to unlock the device.
2.1 Typetesting
The thermostats are tested by the German
Technical Inspectorate (TÜV) according to
DINEN14597.

A shift of the switching point arises when the ambient temperature at the
knob and at the capillary tube deviates from the calibration ambient temperature of +22°C:
Higher ambient temperature g Lower switching point
Lower ambient temperature g Higher switching point
This inuence is minimized by temperature compensation.

DANGER
Risk of electric shock.
− Upon installation of the electric cables,
you are required to observe the regulations concerning low-voltage installations
according to DINVDE0100 as well as
the regulations of your local power supplier.
− Only use a suitable power supply which
guarantees that no dangerous voltages
reach the device in normal operation
and in the event of a fault in the system
or any other system parts.
− Connect the grounding conductor to the
PE terminal.
− The wires of double thermostats are routed
through the opening in the intermediate
wall to the second thermostat. Seal the
opening not used for cable entry with a
blanking cap.
Cable entry
Route the wires through the cable gland
(M20x1.5) into the inside of the thermostat.
The spring-clamp terminals are designed for
a wire cross-section of 0.75 to 2.5mm².
Wiring
Open the thermostat housing and wire the
thermostat according to Fig.5:
− Rigid wire ends: strip 11 to 13mm insu-
lation off the cable and place it into the
terminal point (
) as far it will go.
− Flexible wire ends without ferrules: use a
slotted screwdriver to keep the spring
open (in
the terminal point (
) and place the wire ends into
) as far they will
go.
− Flexible wire ends with ferrules: t
ferrules to the wire ends. Refer to
EN60947-1. Use a suitable crimping
tool.
Place the wire ends into the terminal point
(
) as far they will go.
Note
The wire ends can be pulled out by holding
the spring open with a slotted screwdriver (in
).
