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 fullls 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 page14).

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 8K, 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 4K, 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
DINEN14597.

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 inuence is minimized by temperature compensation.
