32 Culligan® Culligan Top Mount (CTM) Water Filters
32 Cat. No. 01029343
Auxiliary Outputs (P/N 01020748)
The auxiliary board (Figure 39) comes installed in all CTM softeners and filters. It has four 24 VAC outputs for driving
24VAC control valve motors, energizing 24VAC relay coils, or 24VAC solenoids directly. Each solid state triac output is
capable of handling up to 4 Amps maximum; HOWEVER, the 24VAC transformer determines how much total current is
available. Max supply current of the 01014897 transformer is only 2.1 Amps, so the sum of all loads on the triac outputs
should never exceed the maximum that the transformer can supply. The Auxiliary Outputs (see Figure 40) can be pro-
grammed to be “normally off” (output stays OFF until the designated time, it is needed to be ON) or “normally on” (output
stays ON until the designated time, it is needed to be turned OFF).

Aux Output 1 is used to power the 24 VAC drive motor found on all valves. When Aux Output 1 is used for this, then Aux
Output 4 is automatically configured to operate a solenoid which can be used for a standby or blocking. Aux Output 4 is
powered during all cycles except service, and unpowered during service.
For example, Figure 41 shows how the timing would work if an auxiliary output is set to NORMALLY OFF. The cycle posi-
tion is set to BACKWASH, the delay minutes setting is greater than zero, and ON minutes is greater than zero.
