Timer with Firemans switch

[Wiley$]

Hi all,

do the Suraielec Digital Pool timers require a fireman switch or are they programmed to shut heater off before pump?

thanks

You want to turn a pool heater on and off using the "Firemans Switch" and not by cycling the power.

Are we discussing a gas heater or a Heat Pump?
