I have hired a company to install omnilogic pool automatiion. Everyhing works but the heater. They are not returning my phone calls. I think i have identified the problem the pig tail hooked to the remote conection has three wires with labels. 1 spa/hotub combo (for two wire connection ) 2 common ( to be used in either 2 or 3 wire connection. 3 spa only ( only ro be used for three wire connection). They chose to hook up the number one two wire connection pool/spa and the number 3 spa only and left the common unhooked using a two wire connection. My question is does this sound right leaving the common not hooked up and could this create a sf code which i now have since this has been done. It took a week or so for sf code to pop up so that is how i know heater is not working with the omnilogic. All other functions on onnilogic work beautfully.
