The matching terminal assignment to your system or hydraulic diagram, see the descriptions in the respective

hydraulic diagram, see " Hydraulic Variants " on page 6.

Electrical Connection

Before working on the unit, switch off the power supply and secure it against being switched on again! Check that there

is no power flowing! Electrical connections may only be made by a specialist and in compliance with the applicable

regulations. The unit may not be put into operation if there is visible damage to the housing, e.g. cracks.

The unit may not be accessible from behind.

Low-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed

temperature sensor cables only into the left-hand side of the unit, and mains voltage cables only into the right-hand

side.

The customer must provide an all-pole disconnecting device, e.g. an emergency heating switch.

The cables being connected to the unit must not be stripped by more than 55 mm, and the cable jacket must reach into

the housing just to the other side of the strain relief.

Wall Installation

1. Unscrew cover screw completely.

2. Carefully pull upper part of housing from lower part.

3. Set upper part of housing aside Do not touch the electronics.

4. Hold the lower part of the housing up to the selected position and

mark the two mounting holes. Make sure that the wall surface is as

even as possible so that the housing does not become distorted

when screwed on.

5. Using a drill and size 6 bit, drill three holes at the points marked on

the wall and push in the plugs. Optionally the housing can be mount

with 4 mounting holes.

6. Insert the upper screw and screw it in slightly.

7. Fit the upper part of the housing and insert the other two screws.

8. Align the housing and tighten the three screws.

Installing the Temperature Sensors

The controller operates with Pt1000 temperature sensors which are accurate to 1 °C, ensuring optimal control of system func-

tions.

If desired, the sensor cables can be extended to a maximum of 30 m using a cable with a cross-section of at least

0.75 mm². Ensure there is no contact resistance! Position the sensor precisely in the area to be measured! Only use

immersion, pipe-mounted or flat-mounted sensors suitable for the specific area of application with the appropriate

permissible temperature range.

Low-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed

temperature sensor cables only into the left-hand side of the unit, and mains voltage cables only into the right-hand

side.

Operation

Display and Input

Warning/Error message

New information available

The display‘s (1), extensive text and graphical mode,

enables simple, almost self-explanatory, operation of the con-

troller.

Entries are made using 4 keys (2+3), to which contextual

functions are assigned. The ‚esc‘ key (3) is used to cancel an

entry or to exit a menu. If applicable, a request for con-

firmation appears to save the made changes.

The function of the other 3 keys (4) is shown in the display

right above the keys. The right-hand key generally has a con-

firmation and selection function.

The graphics mode appears if no key is pressed for 2

minutes or after exiting the main menu with ‘esc’.

Hitting the "esc" key in the graphics mode takes you directly

to the main menu.

Examples for key settings:

+/- Increase / decrease values

▼/▲ Scroll down / up menu

Yes/No agree / reject

Commissioning help

1. Set language and time

2. Commissioning help / setup wizard

a) select or

b) skip.

The setup wizard guides through the necessary basic settings in the cor-

rect order. Each parameter is explained in the control

display. Pressing the „esc“ key takes you back to the previous setting.

b) With free commissioning the settings should be made in the following order:

lmenu 10. Language

lmenu 3. Time, Date and Operating Times.

lmenu 5. Heating Circuit Settings, all values.

lmenu 6. Protection Functions (if any adjustments necessary).

lmenu 7. Special Functions (if any adjustments necessary).

The setup wizard can be accessed in menu 7.2. at any time.

Consider the explanations for the individual parameters on the following pages and check if further settings are

necessary for your application.

3. In Menu operating mode “Manual”, test the switch outputs with the consumers connected and check the sensor values for

plausibility. Then set to automatic mode.see " Manual " on page 10

1. Measurement values

Serve to display the current measured temperatures.

If ‚error‘ appears on the display instead of the measurement

value, there may be a defective or incorrect temperature sensor.

If the cables are too long or the sensors are not well-placed, small

deviations in the measurement values may occur. In this case, the

display values can be compensated by adjustments in the con-

troller - see ‚Sensor calibration‘. The selected program, con-

nected sensors and the specific model design determine which

measurement values are displayed.

2. Statistics

Serve for function control and long-term monitoring of the system.

For system data statistics it is essential for the time to be set

accurately on the controller. Please note that the clock con-

tinues to run for about 24 hours if the mains voltage is inter-

rupted, and afterward must be reset. Improper operation or an

incorrect time may result in data being cleared, recorded incor-

rectly or overwritten. The manufacturer accepts no liability for

the recorded data!

Operating hours

Display of the operating hours of the relay connected to the controller, whereby different time ranges (day-years) are available!

Heat quantity

Display of the consumed heat quantity form the system in kWh.

Graphic overview

This results in a clear illustration of the data as a bar graph. Different time ranges are available for comparison. You can page

through with the two left keys.

Error Messages

Display of the last 15 errors in the system with indication of date and time.

Reset / Clear

Resetting and clearing the selected statistics. Selecting ‚all statistics‘ clears everything except the error log.

3. Operating mode

To specify the operating modes for the heating circuit. After an interruption of

the mains voltage, the controller automatically returns to the last operating

mode selected.

Only in automatic mode does the controller use the set operating

times and the correspondingly set target flow temperatures!

Automatic

The automatic mode is the normal mode of the controller. A correct controller function under consideration of the current tem-

peratures and the set parameters is only present in automatic mode! After an interruption of the mains voltage, the controller auto-

matically returns to the last operating mode selected.

Manual

In ‚Manual‘ mode, the individual relay outputs and the connected consumers can be checked for proper functioning and correct

assignment.

The operating mode ‚Manual‘ may only be used by specialists for brief function tests, e.g. during commissioning! Func-

tion in manual mode: The relays and thus the connected consumers are switched on and off by pressing a key, with no

regard to the current temperatures and set parameters. At the same time, the current measurement values of tem-

perature sensors are also shown in the display for the purposes of function control.

Off

If the operating mode “off” is enabled, all control functions are turned off. The measured temperatures are displayed for

the overview.

4. Settings

The basic settings for the control function of the heating circuit are applied.

Basic settings applied.

By no means does the controller replace the safety appliances on

site!
