DUAL CLIMA R
6.6.6
Connecting a backup source of energy for Heating installation (E2)
The
DUAL CLIMA R
heat pump allows the connection of a backup electrical heater for Heating
installation (optional). Within the wide range of accessories for heat pumps,
DOMUSA TEKNIK
offers
the optional HP Hydraulic Kit that includes a heating electrical heater (2,500 W).
The electrical connection of the heater will be made between terminals
E2L
and
N
(Neutral) of the
component terminal of the heat pump.
The relay that activates the electrical heater has a maximum capacity of 20 A of consumption.
Therefore, to connect a heater exceeding 4,500 W, a contactor must be interposed between the
terminals of the power terminal and the heater.
As alternative to the backup electrical heater,
DUAL CLIMA R
heat pump allows the connection of a
conventional source of energy as gas boiler, oil boiler, biomass, etc. For it, the heating installation must
be provided with an auxiliary system of water heat exchange that allows the hydraulic connection of
the above mentioned backup source of energy, preferably it should be independent from the water
circuit of the heat pump.
They are used the same terminals
E2L
and
N
(Neutral) of the components powerstrip to make the
connection between the backup source of energy and the heat pump. Depending on the installation
characteristics and the type of the backup boiler, the electrical connection could be made at least by 2
different ways:
Direct connection
In this type of connection it is used the powered output of
E2
relay (230 V~; maximum 20A) to activate
directly the backup energy source (switch on the boiler, activate the backup circulating pump, etc.).
For it, connect the terminals
E2L
and
N
of the heat pump to the main power supply input of the backup
boiler and/or of the device of the installation provided.
NOTE: When the backup source of energy is connected, it has to be taken in account that
the maximum capacity of E2 relay is 20 A.
