Waterco Aquamaster
I pg 17
Heater Control
The Aquamaster provides a set of low voltage dry
contacts (labeled NORMALLY OPEN CONTACTS 1 & 2)
which may be connected to most gas heaters or heat
pumps with 24V control circuits. Refer to the diagram
above for connection to the Aquamaster Control system.
The manuals supplied with most heaters also include
specific wiring instructions for connecting the heater to an
external control. Any conventional heater to be controlled
by Aquamaster should be set to maximum temperature.
Connection of Communication Cable to Waterco ECO Pumps
Waterco ECO pumps may be purchased with the communication cable fitted. Consult your local
Waterco sales office for order details.
Step 1 – Unscrew the 3 x Philips head screws holding the control housing to the motor.
Step 2 – Lift the control housing off the pump to reveal the motor control box.
Step 3 – At the rear of the motor control box drill a 12mm hole at the position indicated in the
drawing below. Use stepped drill bit sizes starting at 4mm and working up to 12mm, otherwise
there is a high risk of damaging (splitting) motor control box.
Step 4 – When the hole is drilled remove the locking nut from the cable gland and thread the cable
through the hole so that the plug is now located within the motor control box. Thread the lock nut
over the cable and screw onto the cable gland and tighten.
Step 5 – Locate the motor control socket on the underside of the control housing and insert the
control cable plug and then reattach control housing to the motor control housing.
