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
nally 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.
