2.5 Connecting a Henden H8VSPBT pump
The following section should be read in conjunction with
the installation and operating instructions of the Henden
H8VSPBT pump. This option requires the installation of a
secondary relay.
To achieve maximum heating efficiency from the Henden
heat pump, connect a Henden H8VSPBT pump using
an RJ45 cable. When connected and the Henden heat
pump detects your pool needs to be heated, it sends a
signal to turn the Henden H8VSPBT pump to full speed
(or an overridden speed selected by you
)
. You will need
to purchase a separate relay to accommodate this.
Specifications of relay required:
• 24V AC coil;
• No contact;
• Contact current: 1A minimum;
• Screw contacts preferred as they can be connected
to the RJ45 network cable used to signal the Henden
H8VSPBT pump more easily.
Figure 3
There is a 17.5mm rail available inside the Henden heat
pump for the electrician to use to mount the relay.
Alternatively, a panel mount relay may be used.
For this feature to work correctly, both the Henden heat
pump and Henden H8VSPBT pump must be run at the
same time.
WARNING: The electrical connection
should be done by a qualified electrician
according to national, state and local
city codes and standards.
The Henden heat pump uses a 24V AC contactor to turn on
the compressor to operate. Depending on the system your
chosen speed of the Henden H8VSPBT pump will require
connections as shown in the following diagrams:
