1 Important Information
During start-up, observe the respective national safety
regulations and the applicable VDE safety regulations,
particularly VDE 0100, as well as the technical connection
requirements of the utility companies (EVU) and network
operators!
The heat pump controller should only be operated in dry
rooms with temperatures ranging between 0 °C and 35 °C.
Ensure that no condensation forms on the device.
All sensor connecting cables with a conductor cross-section
of 0.75 mm can be extended to a maximum of 40 m. Sensor
leads should not be installed next to power cables.
2 Heat Pump Manager: Scope of Supply
The heat pump manager is available in three versions.
Integrated in the heat pump casing
Wall-mounted heat pump manager
for a heat pump heating system
Wall-mounted heat pump manager
for a heat pump system for heating and cooling (Chap. 12 on
p. 33).
3 Installation
3.1 Attaching the wall-mounted heat pump manager (heating)
The controller is attached to the wall with the 3 screws and
dowels (6 mm) included in the scope of supply. The following
mounting procedure should be used to avoid soiling or damaging
the controller:
Mount the dowels for the upper fastening eye at operator
level.
Screw the screw into the dowel so that the controller can be
mounted.
Hang the controller on the upper fastening eye.
Mark the position of the side drill-holes.
Remove the controller.
Mount the dowels for the side drill-holes.
Re-hang the controller and tighten the screws.
To ensure that the frost protection function of the heat pump
works properly, the heat pump controller must remain
connected to the power supply and the flow must be
maintained through the heat pump at all times.
The switching contacts of the output relay are interference-
suppressed.
Therefore,
resistance of the measuring instrument, a voltage can also
be measured when the contacts are open. However, this will
be much lower than the mains voltage.
Terminals J1 to J11, J20 and J23, and the terminal strip X3
of the N1 heating controller are connected to an extra-low
voltage supply. If, due to a wiring error, the supply voltage is
mistakenly connected to these terminals, the heat pump
controller will be destroyed.
The scope of supply of the wall-mounted heat pump manager
includes:
Heat pump manager with casing
3 dowels (6 mm) with screws for wall mounting
External temperature sensor
Operator's manual and operating instructions for users
Installation and start-up instructions for technicians
