, posted Sun 9 Nov 13:42  
I have a brand new Ruud "reverse cycle" unit, in a new constructed apt that is hot water plumbed. When I switch to heat there is no hoter flow because of a unoperating recirculating pump. Might anyone know where I can find a diagram that would show thw heat thermostat color codes, or suggust a better place to start? I have determined that the pump has 120v, but the relay isn't aparently energizing.
Thanks guys, Rob

There is no standard colour codes. We try to use White for heat, Red or black for power, yellow or blue for coolng but there is no standard.

The best way to escape a problem is to solve it.
