Room Temperature Controller

with LimiterFIT 3L

468931003 591-5



1 Principle of operation

The programmable temperature controller FIT 3L allows

programming switching events (up to 9) and temperatures

according to personal needs. After installation the device

automatically shows the time of day and the room tempera-

ture. In AUTO mode, the heater will be automatically activat-

ed according to programmed time and temperature. Program

1 is the default pre-set program (see 8.).

Room temperature will be controlled, the floor temperature

will be limited (measured by the remote sensor). The heater

will be switched on when the temperature drops below the

current set-point.

In case of function "Min Floor Temp" (H3) it will be heated if

the floor temp drops below the set min-value. This is even

when the room temp. is too high.

In case of function "Max Floor Temp" (H3) heating will be

stopped if the floor temp exceeds the set max-value. This is

even when the room temp. is too low.

2 Installation

3 Use

The electronic Room Temperature Controller FIT 3L can be

used to control the room temperature in conjunction with:

• Electrical floor heating systems where the floor tempera-

ture has to be limited to a certain value

• Hot-water floor heating systems in conjunction with ther-

mal actuators

In order to measure the floor temperature the remote sensor

has to be used

Caution!

This device must be installed by a qualified electrician,

according to the wiring diagram on the device and in com-

pliance with all applicable safety regulations.

Appropriate installation measures must be taken to achieve

the requirements of protection class II.

This device, is used to control the temperature only in dry

rooms, under normal environmental conditions. This elec-

tronic device conforms to EN 60730, It is an “independently

mounted control” and works according to operating princi-

ple 1C.

8. Pre-set programs

There are 3 pre-set time/temperature programs in the

controller. Pre-set program 1 (as shown below) is the default.

Therefore, if pre-set program 1 is the best program to suit the

application, there will be no need to change the

time/temperature settings on the device.

To select another program see 9. G1.

Notes for Programming

• Activated settings terminate automatically 3 Min after the

last key press, without saving. They return to the mode

which was active before entering the settings, e.g. AUTO,

MAN, etc.

• Entering a Code: change value with +– key then press OK

• When going through User- or Installer settings the item

number used in the manual will be displayed, e.g. G1 for

"Program select one" or H2 for "Control Mode".

• There may be gaps in the sequence of menu numbers.

Troubleshooting

1. It is getting warm too late:

a. Are clock and program events set correctly?

b. Is the Optimum Start feature switched on? see H7

Did the controller have enough time (several days) to

adapt to the room’s characteristics?

c. Is an automatic change between Summer- and Winter

time activated, see G5

2. The controller does not accept any changes

Is access protection switched on? see G6

3. The range of temperature setting is limited.

Are temperature limits set? See G7

4. Temperature display doesn‘t change.

Is display of set-temperature activated? See G10

5. The room heats up too slow

The floor temperature may be limited from the controller's

max-limiter. See H3

6. The room becomes too warm

The floor temperature may be limited from the controller's

Min-limiter. See H3

Connecting the remote sensor

The FIT 3L needs a remote temperature sensor. This sensor

should be mounted in such a way that the temperature which

has to be controlled, can be measured correctly. Lay sensor

inside a protective tube (simplifies replacement). The sensor

lead can be extended up to 50m by using a cable and

connections suitable for 230V. Avoid laying sensor cable

alongside power cables, for example inside a conduit.
