Rheem RPRL Heat Pump 501 tstat.

[Jim9988]

Hello,
I had a new split system installed last month (rheem rprl and rhpn 5 ton) with the comfort control 2 communicating tstat. My installer was not too familiar with the system. I notice the outdoor temp is reading 50 degrees more then the actual outdoor temp. I cannot find anyone who knows why this is. Would any of you guys have an idea why?
Thanks
Jim

Is it on the south side of the house.

[Jim9988]

Hello. Yes it is. However, it has done this at night without sun and also has given me much lower temp readings. It's was installed a month ago and seemed fine at that time. I noticed the odd temp readings a couple weeks ago. Is it common for the sensor to go?

Not common, but it does happen. More likely its a wiring problem.

Hello,
Can the T-stat wires being too close to the hi voltage lines cause this? Last night it read 155 and this morning 164 - it was n the 60's last night.

It can.

Thanks for your help. This seems to be a tough issue to resolve and not much info online about it. If anyone on this board heard of this problem let me know.
