I'm replacing my single speed WhiperFlo 2HP pump with a EcoStar Variable speed pump.
And I'm looking over the wiring realizing that the existing mechanical timer cuts the power to both
the pump and the heater to prevent the heater from being on when the pump is off.
Well I'm planning on using the digital timer built into the Ecostar to control when the pump goes off and on,
so how can I have the same protection to cut off the heater when the pump is off?
I suppose I could put a current sensing relay on the pump power to cut the power to the heater,
but I'm curious if that is what most installers would do?
Any suggestion would be helpful,
