INSTALLATION INSTRUCTIONS

Pump Start Relay Connection (Water supply by pump system)

This controller does not provide mains power to drive a pump. A pump must be driven

via an external relay and contactor setup as detailed below. The controller provides

a low voltage signal that actuates the relay which in turn enables the contactor and

finally the pump.

HINT: Although the controller has permanent memory and thus a default program

will not cause erroneous valve actuation as in some controllers, it is still good

practice when using a system where the water supply comes from a pump to

connect unused stations on the unit back to the last used station. This in effect,

inhibits the chances of the pump ever running against a closed head.

Single Phase Pump Installation

Link any unused

stations to the

last active station.

Note:

It is recommended to always use a relay between the controller and the pump

starter.
