Eberle FITnp 3R Programmable Thermostat

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-temperature 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.

Installation

Caution! This device must be installed by a qualified electrician, according 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 protection 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 “independently mounted control” and

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 convertor heaters
• Oil or Gas heaters
• Circulation pumps
• Heat pumps
• Electric convector heaters, ceiling and storage heating
• Cooling equipment

• The time limit for manually changed temperature
• Arm chair programming (with display unit removed)
• OFF-Function, Key V to be pressed for 10 sec
• Timer (Party) specific temperature for configurable duration
• Energy consumption display (heating on time * cost) for last 2 days, -week, -month, -year
• Energy cost per hour configurable
• Frost protection
• Range limits for adjusting max and min temperature
• Access protection
• Operating language can be selected
• Control mode PWM or ON/OFF
• Minimum output on/off time and hysteresis configurable for ON/OFF control
• Valve protection
• Heating or Cooling can be selected.
• Adaptation to valves normally open or normally closed
• Measures the room temperature with the internal sensor or a remote sensor

Electric connection
Connecting according to Wiring Diagram For flexible or solid wires 1 – 2,5mm2

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 connections suitable for 230 V. Avoid laying sensor cable alongside power cables, for example inside a conduit.

Mounting

The controller should be mounted at a location in the room which:

• can be easily accessed
• is free of curtains, cabinets, shelves, etc.
• allows free air circulation
• is not exposed to direct sunlight
• is not draughty (when doors or windows are opened)
• is not directly influenced by the source of heat/cooling
• is not located on an outer wall
• is approx. 1.5 m above the floor

Fitting

• in a conduit box Ø 60 mm
• remove the display unit
• remove the frame
• Mount it following the reverse procedure

To insert or remove a flexible wire press pin

Technical Data

Wiring Diagram / Dimensions

Remote sensor F 193 720 (as accessory)

ECO-Input 
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 accordingly.

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

• The controller does not accept any changes
• Is access protection switched on? see G6
• The range of temperature setting is limited.
• Are temperature limits set? See G7
• The temperature display doesn‘t change.
• Is a display of set temperature activated? See G10

Description of Functions and Operation

Selecting languages

• Only for products where no language is pre-set, user has to set up his language by doing this:  + – to select language
• (This input is only requested at first start or Reset 2 x OK to accept -> T+ will be displayed (to change language again use menu G14)
