INSTALLATION & OWNERS MANUAL
4.3 Interfacing equipment to the Henden
Variable Speed Pump
The Henden Variable Speed Pump can be controlled by
other equipment to turn it on to high speed (or any other
preset speeds, see chapter 8 for details). This is to achieve
maximum efficiency, for example, when using a gas
heater, or a heat pump.
If the equipment has an isolated 18- 24V DC signal output,
simply connect pin 7 to 24V DC positive and pin 5 to DC
ground as shown in the following diagram:
If the controlling equipment does not have 18-24VDC
voltage output as above, and it has 24VAC, 230VAC,
12AC or 12 DC etc. signal output, a suitable relay (the coil
voltage must be the same as the signal output voltage of
the controlling equipment) can be used to do this job as
mentioned above, and shown in the following diagram:
If the controlling equipment already has the relay output
(dry contact) for controlling purpose, an extra relay is not
necessary, simply connect Pin 7 (Brown/White) and Pin
8 (Brown) to the dry contacts as shown in the left part of
the diagram above.
4.4 Analogue Control Input
Speed control can also be achieved by connecting a 0-10V
DC signal at the input on pin 4 (ground at pin 5). As soon
as a signal above 0V is registered, this input will take
priority over dial settings. For example, 10V DC will change
pump speed pump to 100%, 5V DC will change pump
speed to 50% etc.
