    Hi Paul,

    Do you have Master valve(Pump) enabled on Zone 1? Have you measured with a voltmeter set to AC power between Zone 1 and common and you don't get any voltage when you start Master Valve/Zone 1? As a test, you can disable  the master valve and test zone 1 manually and see if it outputs any voltage. Please check the Master Valve and pump relay article .

    Note that the RainMachine is a 24VAC device and will not drive the pump, it will simply activate the on/off relay, which in turn can switch on/off power to a pump . Most pumps require 220V to operate.
