DANGER

Risk of serious damage to property and personal injury, e.g. from fire or electric shock, due to incorrect electrical installation.

Safe electrical installation can only be ensured if the person in question can prove basic knowledge in the following areas:

• Connecting to installation networks

• Connecting several electrical devices

• Laying electric cables

These skills and experience are normally only possessed by skilled professionals who are trained in the field of electrical installation technology. If these minimum requirements are not met or are disregarded in any way, you will be solely liable for any damage to property or personal injury.

CAUTION

The protective insulation conforms to IEC/EN

60730-1 when correctly installed on a level, nonconductive, inflammable surface.

Installing the insert

1 Wire the insert according to the corresponding circuit diagram.

| Observe the following:

• Ensure that neutral conductor N is connected to terminal N. If it isn't, this will result in significant temperature fluctuations because the insert is not able to work properly.

• When using conductors with a cross-section of

2.5 mm², we recommend using deep installation boxes to make installation easier.

• A protective conductor does not have to be connected as the insert is insulated.

• LED on = insert switched on.

Introduction to the room temperature control unit

The freely mountable electromechanical room temperature control unit insert (referred to as insert from here on) is used to control the temperature in dry and enclosed spaces, such as flats, schools, halls, workshops, etc., with normal ambient conditions.

Selecting an installation site

• Installation on interior walls opposite the heat source is preferable.

• Mounting height: approx. 1.5 m above the floor.

• External walls and draughts from windows and doors should be avoided.

• Ensure that the warm air in the room has free access to the insert. To this end, the insert should not be installed inside shelving units or behind curtains and similar coverings.

RF

• External sources of heat have a negative effect on the accuracy of the control unit. Therefore, avoid direct sunlight, proximity to televisions, radio and heating appliances, lamps, fireplaces and heating pipes.

• A dimmer generates heat too!

If the insert is installed with a dimmer in a shared switch frame, the two should be as far apart as possible. If they are arranged one on top of the other, the insert must be below the dimmer.

2 Installing the insert

| To ensure that the insert functions properly, the support ring must always be fitted on a finished wall. It must not be wallpapered over, for example.

3 Insert rocker switch G into the switch base (for

MTN536302, MTN536304, MTN5760-60.. and

MTN5761-60.. only).

4 Place frame C and central plate D on the insert and fasten using screw E .

5 Push on setting knob F .

Commissioning the insert

When commissioning the insert, be aware that the bimetallic element needs time to adjust to the room temperature. Therefore the switching point will deviate from the room temperature directly after installation or after night economy is switched off. The switching point becomes accurate after approx. 1 to 2 hours of operating time.

We therefore recommend an initial set temperature that is higher than actually required so that initial heating and initial temperature equalisation are faster. After the temperature has been reached, the temperature setting can be set to the setpoint value required.

B Setting knob for temperature preselection

Use the setting knob to set the temperature required.

The scale corresponds to a temperature range of approx. 5 to 30°C.

Limiting the temperature adjustment range

A B max min

A Red ring (max.): highest temperature that can be set

B Blue ring (min.): lowest temperature that can be set

The insert is factory-set to a maximum adjustment range of 5 to 30°C.

There are 2 adjusting rings in the setting knob. These can be used to limit the temperature adjustment range within the minimum and maximum values.

Setting procedure

1 Turn the setting knob to roughly the middle of the required adjustment range.

2 Remove the setting knob.

3 Insert the tip of a ballpoint pen into the hole and turn the ring to the required temperature limit.

The red adjusting ring needs to be turned anticlockwise.

The blue adjusting ring needs to be turned clockwise.

4 Put the setting knob back on.
