cuit is energized to either start the system pump or open
the master valve.
40
Pump Delay Time
The amount of time the Pump/Master Valve control cir-
cuit is energized before watering begins. The delay time
is adjustable from 1 to 60 seconds.
Pump Start Relay
When the ECXTRA timer is used to start a pump, a 24 V
a.c. relay switch is used to connect high voltage to the
pump starter. The timer is not designed to connect
directly to the pump start circuit.
Rain Delay
This feature enables all watering operations to be
delayed from 1 to 7 days. For example, rain is forecast in
your area for the next two days. Instead of turning the
timer off (and possibly forgetting to turn it back on), a
rain delay of 3 days can be easily entered. At the end of
3 days, the timer will resume automatic operation as
scheduled.
Rain Sensor
A rain sensor is a remote device which can be connect-
ed directly to your ECXTRA to automatically interrupt
watering during rain. When the rain sensor absorbs rain
water it automatically signals the ECXTRA to suspend all
watering operations.
Rain Sensor Control Switch
The sensor control switch is provided to enable the sen-
sor operation to be turned On and Off as needed.
Rain Sensor Configuration Switch
Rain sensors can be Normally Open or Normally Closed
type. The Rain Sensor Configuration Switch enables you
to use either type of sensor with the ECXTRA timer by
placing the switch in the appropriate position.
