Hi All!
Opened my pool for its second season. Haven’t gotten any heat out of my Pentair Ultratemp 120 Heat Pump. Only used for one northeast season. Pool was winterized by a professional company. Last season it worked great, heated the 10,000 gallon pool quickly and was even able to make it a huge hot tub (95 degrees) on a few occasions briefly. I was truly impressed w the heat out of the return jets. I only used the pump on fri sat and sundays otherwise it was off.

Now- no heat this season from the return jets. No error codes or alarms however. Ambient air temp this week was 85 and plenty warm.

**** noticed SUCTION TEMP 90 degrees*** this has to be the problem right! Shouldn’t that be down to like 30-40??? Do I just need a refrigerant recharge?

Thanks a million for someone who knows these things and can chime in and gimme insight. Cheers, Jake
