Master Valve And Booster Pump - ET Water SmartBox Generation 4 Serie Guía Para La Instalación

OPTIONAL
Step 9: If applicable, connect master valve and
booster pump
The ET Water controller provides 24 Volt AC
switched power to control a master valve and a
booster pump. A standard 24 volt master valve
can be connected directly to the MV terminal
and any VC terminal. To specify the type of
master valve, press the MASTER VALVE SETUP
button and select the value corresponding to
either "normally open" or "normally closed. "
Booster pumps require the use of an external
relay to switch the high power required by the
pump. The coil of the relay must be rated for
24 Volt AC operation. Connect the coil of the
pump control relay to the MP terminal on the
base module and any VC (Valve common). The
contacts of the relay are connected between the power source (usually 120V or 240V AC) and
the appropriate leads on the pump motor. The contacts of the relay must be rated to handle the
voltage and horsepower and/or current of the pump motor.
