4.1 General
The following connections must be established on the Smart
RTC (RT Econ A or RT Econ U):
Power supply
Data cable between heat pump manager (N1) and Smart-
RTC (N24)
The Smart-RTC must not be covered by furniture, wall paper or
anything else. It must be ensured that the controller is not
exposed to external heating or cooling sources (e.g. draughts in
cavity walls, rising pipes) even on the rear within the flush-type
box. Operation close to devices which do not comply with the
EMC guidelines can also interfere with the functioning of the
device.
The Smart-RTC should be installed at a height at which the
display is easy to read (approx. 1.5m).
4.2 RT Econ U installation
The RT Econ U is installed in a standard flush-type or cavity box.
The device screw distance of the box must be 60mm. (Device
dimensions see Appendix chapter 2.1 )
Separate the front part (display) from the rear part (mounting)
with a screwdriver (see Fig. 4.1:). Then disconnect the four-pole
cable (see Fig. 4.2:). Connect the voltage supply and the bus
connection (see chapter 4.4 on page E-5 ) to the corresponding
terminals of the controller. Mount the rear part into the flush-type
box using the enclosed screws. The arrow must point upwards.
Before mounting the display, re-connect the 4-pole connector
(see Fig. 4.2:) (reverse polarity protected). Hook in the display at
the bottom, and let it snap into place at the top.
