CONTROLLER FUNCTIONS
01
1. Time Dial. Rotates one clockwise revolution every 24 hours. Controller is programmed
for automatic (AUTO) operation with the insertion of timing pins in the time dial holes.
Once properly set, correct time of day is shown by the alignment of the arrow labeled
“TIME” with the time shown on the time dial.
2. Day Wheel and Retained Pin Assembly. Has 14 pin locations for a two week program.
Controller will operate in AUTO only on the days programmed by the depression of the day
wheel pin. Once properly set, correct day is shown by the alignment of the arrow labeled
“DAY” with the day shown on the day wheel.
3. Auto-Off-On Switch Knob. Indicates the function of the controller by turning to ON for
manual operation, AUTO for automatic operation, and OFF to stop manual (ON) and
automatic (AUTO) functions.
4. Chassis Screws. Secures controller chassis to enclosure.
5. Electrical Connection Strip. Allows for input and output electrical connection. Consult
Electrical Circuit and Connection Diagram prior to wiring,

SETTING AND OPERATING INSTRUCTIONS
03
• TO SET THE DAY OF THE WEEK AND TIME OF DAY: Turn the Day Wheel until correct day
is indicated by arrow labeled “DAY”. Turn the Time Dial CLOCKWISE until the correct time
is indicated at the arrow labeled “TIME”.
CAUTION: Set time dial in CLOCKWISE direction only.
DO NOT FORCE TIME DIAL IN REVERSE DIRECTION.
• TO OPERATE MANUALLY: Turn Auto-Off-On switch to ON. When operation is no longer
needed, turn Auto-Off-On switch back to OFF.
• TO SET DAILY OPERATION: There are 14 days to program on the day wheel. For each
day that operation is desired, the day will pin should be pushed down fully. For days where
operation is not desired, the day with pins should be pulled out gently.
• TO SET OPERATING TIMES: The 24 hour Time Dial has ninety-six 15 minute increments.
The timing pins should be inserted in the Time Dial to indicate the desired operating times.
Included with each controller is a package of white 15 minute pins. Longer timing periods
may be obtained by placing white pins directly next to each other in Time Dial. Also available
are shorter duration 7 minute pins (yellow) and 4 minute pins (orange).
• TO SET CONTROLLER TO OPERATE A MULTIPLE ZONE VALVE: The operating times for
each zone are represented by one pin or by a group of pins in the Time Dial. Omit at least
one pin between each zone of pins in Time Dial.
• TO START AUTOMATIC OPERATION: Once the correct time and day have been set and the
desired operating times have been programmed, the Auto-Off-On switch knob should be
turned to AUTO.

TROUBLESHOOTING
CAUTION:
Important! Disconnect power prior to working on power or load.
07
I. PROBLEM Controller fails to keep proper time.
CAUSE: No power or improper voltage to motor.
SOLUTION: Check Electrical Circuit and Connection Diagram for proper connection
of power to controller. Check voltage supply to ensure voltage to motor
is 120 or 240 volts as specified for model type.
CAUSE: Clock motor running but time dial not turning. Drive gear located behind
time dial may be broken.
SOLUTION: Remove time dial and inspect drive gear. Install new drive gear noting
“this side out”. Reinstall time dial and be sure it turns freely clockwise.
II. PROBLEM Controller improperly staying ON.
CAUSE: Switch is being activated.
SOLUTION: Ensure that wires do not push against switch or relay.
Ensure that wires leading to switch are not pulled out.
CAUSE: Controller improperly wired.
SOLUTION: Check Electrical Circuit and Connection Diagram and make sure
that input wires are not wired directly to load.
CAUSE: Switch adjustment needed for proper automatic operation.
SOLUTION: Make needed switch point adjustment as outlined in part IV of
Troubleshooting Guide.
CAUSE: Switch knob not in OFF position.
SOLUTION: Turn Auto-Off-On knob to OFF position.

III. PROBLEM Controller does not turn ON in manual mode.
CAUSE: No power to controller.
SOLUTION: Be sure that controller is properly wired as per Electrical Circuit and
Connection Diagram.
SOLUTION: Check circuit breaker.
IV. PROBLEM Controller fails to operate properly in automatic (AUTO) mode.
CAUSE: Day Wheel not properly programmed.
SOLUTION: Check Setting and Operation Instructions for programming day wheel.
CAUSE: Auto-Off-On knob not set properly.
SOLUTION: Turn Auto-Off-On knob to auto position.
CAUSE: Switch adjustment needed.
SOLUTION: Remove controller face from enclosure after disconnecting power to unit.
The switch adjustment screw is located on the switch cover. A clicking of
the switch should be heard when the switch arm is slowly pulled back at
the halfway point between the edge of the time dial and the far edge of the
timing pin. With a small screwdriver, tighten the screw clockwise to cause
the switch to activate sooner. If switch is activating sooner than desired,
turn adjustment screw counter-clockwise slightly.
CAUSE: Switch contacts or relay worn out.
SOLUTION: Replace switch or relay (see parts list), ensuring that the controller is
properly rewired. NOTE: A nut driver tool is available to assist in removing
black retainer nuts.
Should the above troubleshooting tips fail to correct the problem you may be having,
please consult your local K-Rain®distributor for service or replacement.
