HELP! Tried to change digital thermostat, now no heat....and its cold!?
Last night I went to change my heat pumps thermostat (a honeywell manual with the mercury inside) to a Digital programmable LUX thermostat (and yes its for a heatpump).
Firstly I killed power to the unit at the breaker, swapped over the thermostat, fired the power back up and nothing, couldn't get heat/cool/or fan.
It was cold last night so I tried to put the old thermo back on, and still nothing.
Any help is greatly appreciated.
Some addt'l info. It has aux. heat. It also has 6 wires:
White
Blue
Red
Yellow
Green
Blue
if you didn't kill the power to the to the furnace you probably shorted the low voltage transformer out the power to the thermostat gets it power from the furnace not the heat pump. the red wire is the feed the green is fan the white is heat the blue is common you then should have 3 wires going to the heat pump
The Computer That Helped Defeat the Nazis Needs Your Aid (Forbes)
During World War II, the Nazis used complex codes to obfuscate commands, and
cracking those codes was one of the keys to the Allies' success. This
codebreaking was accomplished in part by Colossus, the world's first digital,
programmable computer. The National Museum of Computing (NMOC) in Bletchley
Park, England, says that Colossus "shortened the war by two years and...saved
countless thousands of lives." Now it's time for us to help Colossus, or
rather, the NMOC.
