Hunter 44260 Thermostat Install Questions

Post by gringgo » Sat Apr 30, 2011 12:45 pm

I am replacing a very old dial type thermostat with a Hunter 44620 Heat Pump thermostat. Link to 44620 manual...*.*/media/pdf-misc/603274.pdf. Here is a link to the Carrier model the t-stat is for...*.xpedio.*/idc/group ... yx-2pd.pdf. It is called a Single-Package Heat Pump.

I have 5 wires coming out of the wall, but only 4 are used.

Blue ----> O
Green --> G
Red -----> Rc
Yellow -> Y
White --> Not Used

Jumper from Rc to Rh
Jumper from W to Y
A White wire on the old t-stat's board goes to Y

I am ok with Green (G) and Red (Rc), but Blue (O) and Yellow (Y) go to the same place. This does not seem correct since the manual has an OR condition for O and Y. Also, should I jump W and Y?

Any and all assistance is greatly appreciated. Thank you in advance.

John
