Jung TR UD 231 Series Operating Instructions Manual

Safety instructions

The unit may only be opened by an electrician and installed according to the circuit diagram on the unit or in these instructions. Observe existing safety instructions. To satisfy the requirements of protection class II, corresponding installation measures are required. This independently installable electronic device is exclusively for controlling the temperature in dry, enclosed rooms with normal surroundings. This device is in conformance with EN 60730 and functions according to operating mode 1C.

Damage to the device, re or other hazards may

arise if these instructions are not followed. These instructions are a component part of the product and must remain with the end customer.

a limiting function (for example in conjunction

with tiled stoves) – Can be used for “heating only” or “cooling only” – Installable in a box in conformance with

DIN 49073 – Only for use in dry, enclosed rooms

controller with and without a limiting function) – Resetting separate from user and installer settings

Description of functions

The programmable temperature controller

automatically controls the room or oor temperature

depending on the time and day of the week. The automated program can be interrupted at any time by manual entries. The temperature controller has three selectable programs for heating which can be adapted to your individual comfort. The controller is equipped with an internal sensor for measuring the room temperature. In addition, an external remote sensor

can be connected, for example to measure the oor

temperature. The temperature controller compares the measured temperature with set values. If the temperature falls below the current setting, the heating system is turned on. The control method depends on the type of heating and is determined by the installer:

– Room temperature controller: The heating is

turned on when the room temperature falls below

the set target temperature (measured with an

internal sensor or external remote sensor).

– Floor temperature controller: The oor heating

is turned on when the oor temperature falls

below the set target temperature (measured

using an external remote sensor). – Room temperature controller with a limiter

(in conjunction with oor heaters):

The room temperature is measured and

regulated using the internal sensor. An additional

external remote sensor is connected to measure

the oor temperature, and a target temperature

range for the oor is set. The room temperature

control is deactivated when the oor temperature

is outside of this range. If temperature falls

below this range, the heater is turned on, and if

the temperature is above this range, the heater

is turned o󰀨 independent of the current room

temperature.

Four buttons below the display are used to operate the temperature controller (Fig. 2, items (13) to (16)). In the menu, you can activate operating modes, adapt programs and make settings. If a button is not pressed for more than three minutes, the unit automatically switches back to the previous function and the default display (Fig. 2). Program 1 and AUTO mode are the preselected defaults; see “Default programs” and “Modes and setting menus (overview 1)”.

Programming when the controls are removed

The unit can also be programmed when the controls are removed. The current temperature is

not displayed, the “heating mode” display ashes,

and the display is not illuminated. If a button is not pressed for more than three minutes, the display goes dark.

Display information on the current mode

To go to the default display when the controls

are removed and the display is dark, press any button.

• Press O in the default display. Information on the current mode/setting is displayed in the form of a marquee.

• Return to the default display by pressing O.

Selecting modes and setting menus

• Press M in the default display.

MENU briey appears in the function display (8).

A help text as a marquee appears at the bottom edge of the display.

Use the + / - buttons to switch to the desired mode/setting.

• Select the desired mode/setting by pressing O. Another menu opens depending on the mode/ setting.

• Go back to the last display/setting by

pressing M.

• Return to the default display by pressing

several times.

Manually adapting the target temperature

You can always adapt the target temperature in modes AUTO, MAN and TIMER.

• In the default display, press + or -.

The current target temperature ashes.

• Set the desired temperature by pressing + / -.

• Accept the displayed temperature by pressing O. The device returns to the default display.

Turning o󰀨 the controls

• In the default display, press the M button for

10 seconds.

First “MENU” appears in the display. After 10 seconds, the device switches to the default display and “OFF” appears.

• Turn the controls back on by selecting a mode.

Default programs

The controller o󰀨ers three default time/temperature

programs (full-day settings). These full-day settings depend on the selected heating mode (installer settings, H1) and can be selected by the user and adapted to individual heating preferences (user settings, G1 and G2). The factory setting is program 1. The default time/temperature programs are illustrated in the following in sections in graphs and tables.

A specic example is used (room temperature

controller) for program 1 to explain the full-day settings.

Information for electrically skilled persons

Installation and electrical connection

DANGER! Electric shock from touching live parts.

Electric shock can be fatal. Before working on the device, disconnect the connecting lines and cover surrounding live parts.

Installation site

The controller should be installed at a location in the room which is easily accessible for use. When using the internal temperature sensor, the chosen installation site should:

– Enable free circulation of air – Not be in a draft (such as an open window or doors) – Not be located behind curtains, cabinets, shelves,

etc. – Not be exposed to direct sunlight – Not be directly inuenced by sources of heat – Not be adjacent to external walls – Be 1.5 m above the oor.

Fig. 6: Mounting the controls

• Mount the design frame (5) and secure by attaching the controls (1).

Connecting the remote sensor

An external remote sensor is necessary for the modes “Floor temperature controller” and “Room temperature controller with limiter”. The remote sensor line carries mains voltage and can be extended to 50 m with appropriate wires. In order to prevent signal faults, do not run the remote sensor line together with power lines. It is recommendable to run the remote sensor in ducting.

• Connect the remote sensor according to the connection diagram (Fig. 4, item (20)).

• When inserting and removing the connecting line using an appropriate tool, press the release button (Fig. 4/7, item (24)).
