Heating element temperature controller (TC)
The heating element thermo controller regulates the domestic
hot water temperature during heating element operation. The
maximum controller temperature is factory set to 65 °C (the con-
troller and the STL are installed together in a casing). Tempera-
ture settings can be changed using suitable tools (see illustra-
tion). Changes to this setting may only be carried out by qualified
personnel.
In automatic operation (activated via air temperature sensor), the
water is heated by the heating element until the setpoint has
been reached (60 °C). In contrast to heat pump only operation, a
smaller amount of water is heated up to minimise the operating
period of the heating element. In continuous manual operation,
the domestic hot water is heated until the set maximum temper-
ature of the heating element controller has been reached.
Heat pump temperature controller
Temperature control in the domestic hot water cylinder and the
regulation for compressor operation is carried out by the control
electronics.
A temperature sensor (R3) records the water temperature in the
cylinder and another sensor (R1) records the air intake tempera-
ture before the evaporator. A further temperature sensor (R10)
prevents the evaporator from freezing.
3 Storage and transport
3.1 General
The domestic hot water heat pump should always be stored and
transported packaged in an upright position, without being filled
with water. If handled carefully, the device can be transported
over short distances with a maximum tilt angle of 45°. Ambient
temperatures between -20 and +60 °C are permissible during
transport and storage.
3.2 Fork lift (or lift truck) transport
The domestic hot water heat pump must remain mounted on the
pallet when being transported with a fork lift. The pump should be
lifted slowly. Because of its high centre of mass, the domestic hot
water heat pump must be secured against toppling. To prevent
damage, the domestic hot water heat pump must be lowered
onto a level surface.
3.3 Manual transport
The pallet can be used underneath the device for manual trans-
portation. A second or third carrying position can be created with
the help of ropes or carrying slings (these may be wrapped
around the cylinder casing and attached to the water pipe nip-
ples). When transporting the heat pump in this manner (or with a
hand truck), do not, under any circumstances, exceed the max.
tilt angle of 45° (see illustration). If the heat pump can only be
transported in a tilted position, the domestic hot water heat pump
("Heat Pump" switch) should not be operated for at least one
hour after installation in its final location.
ATTENTION!
The device cover cannot be used for carrying (the cover cannot withstand
significant forces).
