InstallatIon InstructIons

PuMP start relay connectIon (water suPPly by PuMP systeM)

This controller does not provide 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.

PuMP InstallatIon

Link any unused

stations to the last

active station.
