Inground Pool/spa Timer Function

[mikepell1966]

Hello,

Recently purchased a foreclosed home where most of the pool equipment was either taken or no good. I'm a HVAC Service Tech, not a pool tech by any means, but learning "on the job". It is an in-ground pool with an attached built in spa which overflows into pool. Main pool pump motor was seized and timer was burnt out so I replaced motor and timer.....those are working fine. There is a separate pump which operates the spa jets and a separate air blower with an air switch. There was an Intermatic 4 function air switch mounted on the wall but the guts were removed. I purchased a new 4 function switch/timer, new air button, hose, and am going to rewire the pump, blower, and air switch. What should be the proper function of this system? Does the pump run only on timer and should that be set just like the main pool pump to run at the same times? And when you are using the spa, do you depress the air button and the blower and pump operate? Or is it just the blower? There is a return and supply running from the main pool pump to a floor return and supply outlet with a 1" female thread (for what I was told is for a fountain head), should those operate with main pool pump? Thanks for your help.

Since you are an HVAC guy, you must be retrained. Water that comes from the pool via the skimmer or main drain is the suction, and water back to the pool is the return( i know, it's backwards). The filter pump normally runs every day(timer) for several hours. You turn on the blower as needed (button),

Depending on the type of air switch you get, you can control one or more accessories, pump, blower, etc. You will probably have to open a valve (1" line) for the filter pump to supply water for fountain to work. You wont that running every day.
