Building Technologies Summary 18.08.2010

3 Mounting and installation
3.1 Regulations
3.1.1 Electrical installation
•Prior to installing the units, power must be turned off
•The connections for mains and low-voltage are separated
•The wiring must be made in compliance with the requirements of safety class II.
This means that sensor and mains cables must not be run in the same duct
3.2 Planning
•Air circulation around the controller must be ensured, allowing the unit to emit
the heat produced by it.
•The controller is designed to conform to the directives for safety class II devices
mounted in compliance with these regulations.
•Power to the controller may only be supplied when fully mounted / electric
installation is complete. If this is not observed, there is risk of electric shock near
the terminals
•The controller must not be exposed to dripping water
•Permissible ambient temperature when mounted and when ready to
operate: 0…50 °C
•Power cables must be clearly separated from low-voltage cables (sensors)
observing a distance of at least 100 mm
3.3 Mounting
•Wall mounting
Mounting location
•Control
panel
The device has two pre-punched connection openings on the back side and six on
the under side. Break out the required connection openings prior to mounting.
Prepare for mounting

4 Commission
To commission the units, the following working steps must be carried out:
Prerequisites
•Make certain that mounting and electrical installation are in compliance with the
relevant requirements.
•Make all plant-specific settings. Special attention must be paid to menu
"Configuration". For that purpose, the relevant operating level is selected as
follows:
•Press the OK button to switch to programming.
•Press the Info button for at least 3 seconds and select operating level
"Commissioning" with the setting knob. Then, press the OK button.
•Make the function check as described below
Function check
To facilitate commissioning and fault tracing, the controller can be used to make
input and output tests. With these tests, the controller’s inputs and outputs can be
checked. To make the tests, switch to menu "Input / output test" and go through all
available setting lines.
The current operating state can be checked on menu "State".
Operating state
For detailed diagnostics of the plant, check menus "Diagnostics heat generation"
and "Diagnostics consumers".

5.4 Programming
5.4.1 Setting principle
Settings that cannot be made directly with the help of operating elements are made
through programming. For this purpose, the individual settings are structured in the
form of menus and operating lines, thus creating practical groups of settings.
The following example shows how to set the time of day and the date.
5.4.2 Example: "Setting the time of day"
•Press OK to go to programming.
•Press the ESC button to go one step back at a time, readjusted values are not
adopted
•If no setting is made for 8 minutes, the display returns automatically to the basic
display
•Operating lines may be hidden, depending on configuration and user level
