My reply is a year late, but maybe it can help someone else. I'm using the HAI 14A00-8 pool sensor with the HAI Omnipro II controller. It seems to be working well and the temp seems to be on target without any adjustments. For heating, you just need to set the heat setpoint and monitor the zone. If you want to add cooling, you will need to wire the sensor zone to a second zone and set the cool setpoint for that zone.
The pool sensor doesn't come with any mounting hardware, so I installed a T before the pump where the T has a 3/4" threaded connection. Took a 3/4" plug, drilled a 1/4" hole making a tight fit for the probe and epoxied the inside of the plug to seal it.
