310,
Assuming you have the IntelliFlo, because the SuperFlo VS won't work, the pump is controlled by a data cable that runs from the pump to the EasyTouch's com port. The IntelliFlo is wired to constant 240 VAC power from a dedicated 20 amp GFCI breaker.
You must wire the IntelliChlor's transformer to the load side of the Pump/Filter relay. The line side of the pump/filter relay gets constant AC power. Either 120 or 240 depending on how you want to power the IntelliChlor.
When the ET tells the pump to run, it will also tell the pump/Filter relay to close.
The heater is controlled via a small relay on the main board... The 240 VAC for the heater is not controlled by the EasyTouch, only a low voltage control singnal from the pump's fireman's switch.
Thanks,
Jim R.
