Note these new 41400 timers are not compatible with the old style 12030 or 03364 timers.

You cannot mix and match the timers on the same unit.

They either all must be the old style, or all must be 41400

NOTE If you have the older terminal block,  you will need to disconnect the wire currently plugged into the ‘ I ’ terminal on the air exchanger, and move it to the ‘ B ’ terminal.

Once that is done, the wiring is as follows:

B= GRND

OL= OVR

OC= 12V
