INSTALLATION INSTRUCTIONS - INDOOR MODELS:
Remove the lower cover. Place the unit on the wall using the top screw slot. Level
the controller, then insert screw into the lower screw hole 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. Connect the transformer wires to the 24 VAC terminal.
Note: A 9 VDC battery must be installed for proper operation of the controller. The 9
volt battery compartment is located on the right side of the case. It is marked “Push”. Push
it to release the battery drawer. The 9 volt battery powers the LCD display in the absence
of AC power and allows “Arm Chair Programming”. Program information is retained
during power outages by an on-board lithium battery.
NOTE: Only after all the wiring is completed and checked should the transformer be
plugged into AC power.
