anyone have advice on wiring the intelliflo with a purex minimax 400 heater? currently there is a mechanical switch that controls the old pump and heater.

saw another post where the advice was to wire the pump to the line side of the switch so it always has power and leave the heater on the load side so it can be controlled with the switch. If the heater was accidentally switched on when the pump was off will that damage the heater having no water flowing in it?

Most heaters have a pressure switch so when the pump is off or even when on a speed that is too low, the heater should not go on.
On my heater the pressure switch is adjustable. I had to adjust it from 5psi to 1psi. Works on low.
