holes under the terminal block.Connect the solenoid wires to the terminal block.

Connect one wire from the solenoid to its respective station number on the

terminal block and the other wire to the C-common terminal. Finally, connect the

transformer wires to the 24 VAC terminal.

9VDC battery. The 9 volt battery compartment is located between the sensor

terminal and the 24VAC terminal.The 9 volt battery powers the LCD display in the

absence of AC power and allows “Arm Chair Programming”.Program information
