Room Temperature Controller FIT 3Rw

(with change over contact)

468931004 122

G

1 Principle of operation

The programmable room temperature controller FIT 3Rw allows

programming switching events (up to 9) and temper atures

according to personal needs. After installation the device auto-

matically shows the time of day and the room temperature. In

AUTO mode, the Heater (Cooler) will be automatically activated

according to programmed time and temperature. Program 1 is

the default pre-set program (see 8.). 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 qualied 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 prin-

ciple 1C.

3 Use

The electronic Room Temperature Controller FIT 3Rw can be

used to control the room temperature in conjunction with:

• Thermal actuators for e.g. water based oor heating or

convector heaters

• Oil or Gas heaters

• Circulation pumps

• Heatpumps

• Underoor heating with heat / cool change over

4 Features

• One line text display for simplied operation

• Back light

• Real time clock (setting of year, month, day, time)

• Automatic Summer- Winter time change over

• Max 9 events per day (each day independently)

• Pre-set and adjustable programs

• Optimum-Start

• Arm chair programming (with display unit removed)

• Holiday-Mode (date from – until can be set)

• Timer (Party) specic temperature for congurable duration

• Relay change over contact (for uses in conjuction with

connection strip EV 230 H/K...)

• Range limits for adjusting max and min temperature

• Access protection

• Operating language can be selected

• Control mode PWM or ON/OFF

• Minimum output on/o time and hysteresis congurable for

ON/OFF control

• Valve protection

• Adaptation to valves normally open or normally closed

• Measures the room temperature with the internal sensor or a

remote sensor

Electric connection

Caution: disconnect electric circuit from supply

Connecting according to Wiring Diagram

For exible or solid wires 1 - 2,5mm

Remote sensor F 190 021 (as accessory)

8. Pre-set programs

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

ler. 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 num-

ber 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

Connecting the remote sensor

F 193 720 or F190 021 (optional)

In order to measure the room temperature, instead of the inter-

nal 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 (simplies replacement).

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

and connections suitable for 230 V. Avoid laying sensor cable

alongside power cables, for example inside a conduit.

Caution!

The sensor is at mains voltage.
