Room Temperature Controller

FITnp 3R

468 931 003 758-3



1 Principle of operation

The temperature controller FITnp 3R makes it very easy to

change over between comfort- and set-back temperature (one

key press). In addition, via an external timer the temperature

can be set automatically to an ECO-Temperature (e.g. for night

set-back).

After installation the room will be controlled to the comfort-tem-

perature T+. The room temperature will be controlled according

to the temperature measured by the internal or remote sensor.

The Heater will be switched on when the temperature drops

below the current set-point.

2 Installation

Caution!

This device must be installed by a qualiﬁed electrician, accor-

ding to the wiring diagram on the device and in compliance

with all applicable safety regulations. Appropriate installation

measures must be taken to achieve the requirements of pro-

tection class II. This device, is used to control the temperature

only in dry rooms, under normal environmental conditions.

This electronic device conforms to EN 60730, It is an “inde-

pendently mounted control” and

3 Use

The electronic Room Temperature Controller FITnp 3R can be

used to control the room temperature in conjunction with:

• Thermal actuators for e.g. water based ﬂoor heating or

convector heaters

• Oil or Gas heaters

remote sensor

Electric connection

Caution: disconnect electric circuit from supply

Connecting according to Wiring Diagram

For ﬂexible or solid wires 1 - 2,5mm2

Remote sensor F 190 021 (as accessory)

8. ECO-Input 2

Via the ECO-Input the room temperature can be controlled to

an energy saving temperature (e.g. via an external timer). The

temperature can be changed by using keys (display then T*). + –

This mode will be indicated on the screen as „ECO“.

The used temperature can be pre-set in menu H7.

Via key T+/T- a change over between the temperatures T+, T-,

ECO

will be possible.

If ECO input becomes in-active, T+ will be activated.

Note: TIMER will not be cancelled, ECO will be delayed accor-

dingly.

Notes for adjustment

• 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. T+, T-, T*, ECO

• 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 „T+

Setting“ or H2 for „Control Mode“.

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

Troubleshooting

1. The controller does not accept any changes

Is access protection switched on? see G6

2. The range of temperature setting is limited.

Are temperature limits set? See G7

3. Temperature display doesn‘t change.

Is display of set-temperature activated? See G10

Connecting the remote sensor

F 193 720 or F190 021 (optional)

In order to measure the room temperature, instead of the internal

sensor an external one can be used.

Remote or internal sensor selection can be made via menu item

H1.

Lay sensor inside a protective tube (simpliﬁes replacement). The

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

nections suitable for 230 V. Avoid laying sensor cable alongside

power cables, for example inside a conduit.

Caution!

The sensor is at mains voltage.
