Installation Diagram - Dimplex Dhw 301P Montage- Und Gebrauchsanweisungen

Connection
NOTE
We strongly advise against using a circulation line.
Connection of a circulation line increases the runtime
of the heat pump and thus results in higher energy
costs.
NOTE
Failure to observe the above points or to comply with
the limit values for the water quality result in all warranty
claims being void.
NOTE
The cylinder has a sacrificial magnesium anode. This
must be checked for wear at regular intervals. Replace
if necessary (measured value < 0.3A if sacrificial
anode is exhausted).

The electrical wiring diagram for integration of a sec-
ond heat generator can be found in chapter 8.5.3.

1 Circulating pump for 2nd heat generator
2 Pressure relief valve
3 Expansion vessel
It is possible to control the second heat generator
using the floating contact on the domestic hot water
heat pump (see chapter 8.3.2) or the controller on the
2nd heat generator using a domestic hot water sensor.
This sensor is located on the rear of the cylinder.

8.3.2. Attaching a second heat generator to the
domestic hot water heat pump with
integrated smooth pipe heat exchanger
Switch off the device.

Remove the cover and the hood from the device.

This is done by unscrewing the screws on the bot-
tom edge of the hood.
Remove the black protective cover from the

switch box.
Insert the sensor in the immersion sleeve provided

(on read of tank).
Connect the temperature sensor for the 2nd heat

generator to the floating contact at terminals 14
and 15 on the domestic hot water heat pump
board (recommended flexible cable 2
with wire end ferrules).
In this case the alarm output is used for the

2nd heat generator.
This enables either the integrated heating element

or the second heat generator to be selected (e.g.
winter/summer operation). By default, the heating
element is selected as the second heat generator.
NOTE
Connecting 230 V at the output for the 2nd heat
generator is prohibited. This destroys the board.
