Installation of Honeywell RTH8500 thermostat - Wiring
Hi,
I currently have a Robertshaw 300-208 thermostat running my Luxaire heat-pump and (some other brand) electric furnace as auxiliary heat. I just bought the Honeywell RTH8500 thermostat to replace it. There are two labels on the Robertshaw thermostat which do not correspond to any label referred by the installation manual for the Honeywell thermostat : "24V" and "24V(c)". I've included pictures of the current wiring. Because some of the labels are hidden in the pictures, here's a top-to-bottom list: W1 Y1 G R 24V 24V(c) O B Here are the pictures: http://www.jpti.ca/IMG_6107_2.JPG http://www.jpti.ca/IMG_6102_2.JPG http://www.jpti.ca/IMG_6103_2.JPG http://www.jpti.ca/IMG_6105_2.JPG Can anyone tell me which of my wires I should connect to which terminal on the Honeywell ? Thanks. |

What a radical idea. Can anyone tell me which of my wires I should connect to which terminal on the Honeywell ? Robertshaw 24V is power to the control circuit 24(c) is the 24V common (like a neutral in a power circuit) R is 24V power to the switches in the stat - jumpered to 24V W1 connects to R for heat - 1st stage - heat pump Y1 connects to R for cooling - 1st stage G connects to R for fan O ??likely 2nd stage heat - electric heat You don't give the terminals for the Honeywell but R-W-Y-G are standard. You may need 24V common to power the Honeywell control circuit - that is the blue wire. Orange is probably the Honeywell second stage heat. As the temperature falls to the set-point for heat, R-W1 connect to run the heat pump. Maybe 2 degrees cooler R-O[probably] connect for electric heat. (I didn't google either Robertshaw or Honeywell. With heat pump and aux heat the Honeywell very probably needs to include 2 stage heat.) -- bud-- |

"You don't know me or my profession." I am a master electrician. It has been a while since I worked on a heat pump. For several years I worked for one of several subs for a major heating company that mostly did furnace replacements and A/C adds to existing systems. I did all the A/C adds to existing zoned heat where the zones had to be defeated for cooling - ie where the many existing systems had to be figured out (which other contractors screwed up). I won't bore you with other information. Or do you always like to guess and post inaccurate information? As I said in my previous post, I think an OP should provided links to relevant information. For my 2nd post I looked them up. The way newsgroups work is people correct the posts of others. You apparently are above posting useful information, like explaining the error in my 2nd post (which you claim is wrong). -- bud-- |

Otherwise, with battery it only lights when you touch it and then remains on for 15 secs or so. |
