FIG. 1 - CONTENT

• Thermostat

• Sensor

The thermostat is an electronic PWM/PI thermostat for temperature

control by means of an NTC sensor located either externally or

internally within the thermostat.

The thermostat is for ﬂush mounting in a wall socket. A baseplate

for wall mounting is also available.

This thermostat can be used as a controller for electric room heating

pursuant to EN50559.

Product programme

OCD5-1999/MCD5-1999 Clock-thermostat with two sensors:

ﬂoor sensor and built-in room sensor.

FIG. 2 - WARNING – Important Safety Instructions

Disconnect the power supply before carrying out any installation or

maintenance work on this thermostat and associated components.

The thermostat and associated components should only be installed

by a competent person (i.e. a qualiﬁed electrician). Electrical instal-

lation must be in accordance with appropriate statutory regulations.

FIG. 3 - THERMOSTAT PLACEMENT

Mounting of sensor

The ﬂoor sensor contains a safety extra-low voltage (SELV) circuit,

allowing it to be placed as close to the ﬂoor surface as possible

without having to take account of the risk of shock should the sen-

sor cable become damaged. The two wires connecting the sensor

to the mounting box must be additionally insulated, e.g. shrink ﬂex.

To prevent loose wires in the ﬁxed installation from coming into

contact with the terminal block for the ﬂoor sensor, they must be

restrained using cable ties.

It is strongly recommended that the cable and sensor are placed in

a non-conductive installation pipe embedded in the ﬂoor. The end

of the pipe must be sealed and the pipe placed as high as possible

in the concrete layer. Alternatively, the sensor can be embedded

directly in the ﬂoor. The sensor cable must be led through a sepa-

rate conduit or segregated from power cables.

The ﬂoor sensor must be centred between loops of heating cable.

The sensor cable may be extended up to 100 m by means of a

separate two-core cable. Two vacant wires in a multi-core cable

used, for example, to supply current to the ﬂoor heating cable must

not be used. The switching peaks of such current supply lines may

create interference signals that prevent optimum thermostat func-

tion. If a shielded cable is used, the shield must not be connected

to earth (PE). The two-core cable must be placed in a separate

pipe or segregated from power cables in some other way.

Mounting of thermostat with built-in sensor

The room sensor is used for comfort temperature regulation in

rooms. The thermostat should be mounted on the wall approx.

1.6 m above the ﬂoor in such a way as to allow free air circulation

around it. Draughts and direct sunlight or other heat sources must

be avoided. No external sensor is connected.

FIG. 4 - OPENING THE THERMOSTAT

1. Slide the power button down to O “0”.

2. Release the front cover ONLY by inserting a small screwdriver

into the slot at the centre of the bottom side of the front cover to

press and hold the catch securing the front cover.

3. Then carefully pull the front cover away, initially from the lower

part of the thermostat, then from the upper part of the thermo-

stat.

FIG. 5 - CONNECTIONS

Connect the wires in accordance with the diagram. The wires must

be connected as follows:

Term. 1: Neutral (N)

Term. 2: Live (L)

Term. 3-4: Output, max. 16 A

Term. X: Do not connect

Term. 5-6: External ﬂoor sensor

MCD5-1999 English

FIG. 6 + 7 - MOUNTING THE THERMOSTAT

1. Mount the thermostat in the wall socket.

2. Fit the frame and carefully press the cover onto the thermostat

- starting with the upper part of the cover, then the lower part of

the cover. Ensure that both the power slide button on the cover

and the power switch pin in the thermostat are down.

3. Click the cover into place by applying light, even pressure.

Warning! Do not apply pressure to the corners of the display

cover or to the display itself.

DO NOT open the thermostat by releasing the four ﬁxing clips on

the back.

FIG. 8 - OPERATING THE THERMOSTAT

There is an ON/OFF switch on the left side of the thermostat: up is

ON - down is OFF.

The resistive touchscreen requires a soft tap with your ﬁngertip to

Installer Wizzard:

The ﬁrst time the thermostat is connected, push the power slide

button to On “I” The Installer Wizard on the touchscreen will guide

you through the set up of:

FIG. 9 - TROUBLESHOOTING

If the sensor is disconnected or short-circuited, the heating system

is switched o. The sensor can be checked against the resistance

table.

Error codes

E0: Internal fault. The thermostat must be replaced.

E1: Built-in sensor defective or short-circuited. Replace the ther-

mostat, or use the ﬂoor sensor only.

E2: External sensor disconnected, defective or short-circuited.

Reconnect the sensor if disconnected, or replace the sensor.

E5: Internal overheating. Inspect the installation.

CE marking

According to the following standard:

LVD/EMC: EN 60730-2-9

Classiﬁcation

Protection from electric shock must be assured by appropriate

installation. Appropriate installation must meet the requirements of

Class II (enhanced insulation).

Environment and recycling

Please help us to protect the environment by disposing of the

packaging in accordance with national regulations for waste

processing.

Recycling of obsolete appliances

Appliances with this label must not be disposed of

with general household waste. They must be collected

separately and disposed of in compliance with local

regulations.
