DIP switch no. 4 is used for switching over to cooling mode when used in cooling
applications.
The setting is made with DIP switch no. 5 while the pump is running. This protects the
pump against seizure during longer OFF periods. Periodic pump run is activated for
one minute every 24 hours at 12:00 h.
In the automatic modes, the setpoints can be entered for every switching point, and
individually in the continuous modes.
When using minimum limitation of the setpoint to 16 °C, undesired heat transfer to
neighbouring flats is prevented in buildings that have several heating zones. The
function can be selected with DIP switch no. 3.
Keep the button behind the little hole depressed for at least 3 seconds. This resets the
individual settings and the time of day to their default values. During the reset time of 3
seconds, the display will be fully lit, allowing the correct functioning of the display to be
checked.
After each reset, all personal settings such as time of day, weekday, switching points,
temperature setpoints, holidays, sensor calibration, etc., must be reentered.
For the holiday function, the start day (maximum 6 days in advance), the duration of the
holiday period and the temperature setpoint must be entered. This means that when
absent for a longer period of time (up to 99 days), the plant can be switched to the
required economy temperature starting on the day of departure. Every midnight, the
counter subtracts one day. When the day counter returns to 00, the operating mode
selected last will automatically be resumed.
Mechanical design
Plastic housing with a large display which also serves as a touch screen. The display’s
lighting is switched on by touching the screen and switches automatically off after 15
seconds.
The controller (top section) can be easily removed from its base by pressing a button. A
hinged battery compartment cover facilitates the straightforward exchange of the two
1.5 V alkaline batteries type AA. The base can be fitted to all commercially available
recessed conduit boxes or directly on the wall and can then be wired before fitting the
controller to it. The housing accommodates the electronics, a
DIP switch and a relay
with a potential-free changeover contact. The connection terminals are integrated in the
base.
