Temperature Sensor - Dimplex LIKI 14TE Instructions D'installation Et D'utilisation

Minimum heating water flow rate
The minimum heating water flow rate through the heat pump
must be assured in all operating states of the heating sys-
tem. This can be accomplished, for example, by installing a dual
differential pressureless manifold. When the minimum flow rate
is undershot, the plate steel exchanger in the refrigerating cycle
can freeze, which can lead to total loss of the heat pump.
NOTE
The use of an overflow valve is only recommended for panel heating and
a max. heating water flow of 1.3 m³/h. System faults may result if this is
not observed.
Antifreeze
Heat pump systems, which cannot be guaranteed to be frostfree,
should be equipped with a drainage option (see Fig.). The anti-
freeze function of the heat pump manager is active whenever
the heat pump manager and the heat circulating pumps are
ready for operation. If the heat pump is taken out of service or in
the event of a power failure, the system has to be drained. The
heating circuit should be operated with a suitable antifreeze if
heat pump systems are implemented in buildings where a power
failure can not be detected (holiday home).

Temperature sensor

The following temperature sensors are already installed or must
be installed additionally:
 External temperature sensor (R1) supplied NTC-2
 Return temperature sensor (R2) installed NTC-10
 Flow temperature (R9) installed NTC-10

The temperature sensors to be connected to the heat pump man-
ager must correspond to the sensor characteristic curve illus-
trated in Fig.7.1 on pag. 9. The only exception is the external
temperature sensor included in the scope of supply of the heat
pump (see Fig.7.2 on pag. 9)
