Preparation of the assembly and start-up
The two fixing screws can be seen in the front housing.
1. Wire and attach all electrical connectors.
2. The controller must be inserted into the intended installation cut-out and fixed
by means of the 2 fixing screws.
Before start-up it must be ensured that all components are correctly attached.
When the plant is correctly installed and ready for use the following safety precau-
tions must be taken:
• check that the protective fuse of the electricity installation is in order
• check that all necessary connectors are joined
• check that all switches are switched on
• check that all necessary sensors are attached
• check that the output functions work correctly.

Start-up
The basic display (as example see the cover page) appears after switching on the
boiler. The parameters can be adjusted afterwards! If no basic display appears,
refer to "6.1 Checking the controller", page 33.
At start-up, determine that:
• the boiler is switched on
• the clock program is correctly programmed
• all temperatures are correctly adjusted
• heating is required according to the outside temperature
• the time and the date are set correctly.
Note:
Due to the automatic summer/winter time change it is possible that the time
may be adjusted by 1 h. The time in each case will not change. The time is
corrected automatically, as soon as the controller is attached at the supply,
on the next day between 2.00 and 3.00 o'clock
In addition, depending upon plant configuration, carry out the following start-up
steps:
• Controller internal function check, see "6.1 Checking the controller",
• Examine the sensors, see "7.2 Checking temperature sensors", page 40
• If all sensors are attached correctly, the sensor configuration must be
saved (Parameter 4-0 = on)
• Switching output functions on and off, see user operating manual.
