OPTIONAL EQUIPMENT

OPERATION

“Off” Setting de-energized the entire control circuit, thus de- energizing all heating circuits in the system.

“Automatic” Setting – allows the Day-Night Clock Panel to cycle the control system according to the program clock dial trip- per settings.

To Set Trippers – refer to picture for typical setup of a Seven Day Program. Two trippers must be used for each day; an “A” tripper for switching from “Night Setback” to “Day Operation” and a “B” tripper for switching from “Day Operation” to “Night Setback”.

WARNING: To set the correct day and time at begin- ning of initial start-up, ROTATE THE PROGRAM CLOCK DIAL CLOCKWISE ONLY. DO NOT ATTEMPT TO TURN POINTER!

Adjusting and Maintenance of Time Switch:

1.Periodically check trippers to insure that they are tightly fas- tened to Program Clock dial.

WARNING: Tighten trippers with fingers only!

2.Rotate Program Clock dial CLOCKWISE one hour in Spring to adjust for daylight savings time (in areas where required). In Fall, carefully rotate clock dial CLOCKWISE approximately one full turn to reset at correct day and time for standard time. Check all trippers to insure they have not moved during rotation.

3.The Program Clock motor is permanently lubricated. Lubrication of other parts is not required.

4.The Program Clock switch contacts are factory set and need no field adjustment.
