Check that the cable you use has the above colour coding pins 1 through to 8.
If an alternative colour coding has been used make sure to record the colour
which corresponds to each pin to avoid misconnection at the pool controller or
heater. If an alternative cable is used make sure the analogue input and ground
are a twisted pair.
The 24V connection is only to be used as a reference for the digital inputs – DO
NOT power external equipment from this supply rail.
Digital Control Inputs
The 3 digital inputs allow for overriding the dial speed setting. To set one of these
inputs either:
1. Connect an isolated 24V supply between ground and the digital input pin
2. Connect the switched contacts of a relay between the 24V pin and the digital
input
The fixed speeds (as a proportion of full speed) are:
Input 1
(Pin 7)
Input 2
(Pin 6)
Input 3
(Pin 3)

Interfacing equipment to the ProMaster PM400BT
WARNING: A qualified electrician is required to carry out the work
shown below.
The ProMaster PM400BT pump with Bluetooth can be controlled by other
equipment to turn it on to high speed (or any other preset speeds, contact
Davey 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:
