Li help Dry contact controller

I just purchased an airscape whole house fan.I am trying to set it up to come on late evening and go off mid mornings by a progammable controller of some sort.The manufacturer tells me any controller with (dry contacts) will work.The switch that came with the unit has on/off and Hi/Lo.I would like to still be able to uses this switch manually to.Any help on fonding a cost effective way to do this would be appreciated Thanks Roky

You could use a water heater timer. You will switch the power leads to the fan and not touch the control circuit. You could do this several different ways, but this would be the easiest.
Check Intermatic Timers on the web. will have to leave the fan in the "ON" mode all the time.
