Chromotherm 1V plus how to put intoAdaptive Intelligent Recovery

This thermostaat was installed when the new furnace was installed almost 5 years ago. I love ther flexability of this Thermostaat but I had the furnace installer come back after a few weeks and disable the Adaptive Recovery function. Our circumstances have changed and I am considering changing back to the Adaptive Intelligent Recovery mode but I do not want to pay $100 to have the guy make a house call. So with that in mind, how really difficult is it to make the change my self. All the manual says is to have the furnace techician come and do it. I am pretty handy with these kinds of things, I configure and put together computers for people as a sideline to my retirement so I am fairly kowledgeable.
Thanks for your help in this matter.

You are going to need the installers manual, inside is the installer set up functions, it will have the code to get you to the adaptive intelligence setting on your stat, I have found living here in the northwest that the A.I.R. setting does not function properly, to cold here for it to function right, people were complianing that it would start coming on well before the programed settings, what it does is anticipates the need of the home and reacts. We here have to shut the function off. Hope that helps

I finally found an installation guide online for this t'staat. All I had t do was go into installers mode on the controller and change a value from "0" to "1". It told me which buttons to push to get into installers mode and which item # to change. In my case it was item number 13.

Rv furnace stopped working

Quick call the installer to see if it is still under warranty. There is something wrong if the motor is being replaced every other year. Most of the motors should be lubed with fan turbine oil and not 3 in 1, nor detergent containing oils. If the wrong oil is used, the bearings will go south in 1 to 2 years.

I have an evcon furnace that was put on brand new about 5 years ago. I have noticed that it doesn't seem to be kicking off and it doesn't seem to be heating my home either. A line was kinked last year...

This going to be little lengthy. The fan can be on from two reasons. If your thermostat has a fan switch, it will say ON or AUTO. Put it to AUTO. Turn your thermostat to its lowest setting and wait 3 or 4 minutes. If the fan stays running, the problem is in the furnace. Newer furnaces have big circuit boards that control all its functions. The fan automatically starts after a factory set period of time (about 45 seconds). Try a HARD reset to get all the furnace functions back to normal. Turn your thermostat as low as it will go. find the breaker or fuse that serves only the furnace. Unscrew the fuse or turn off the breaker for a good minute and replace/reset it. If the fan starts right away, the board is probably bad. PC relays often arc together and the entire board will need replacement. If the fan is off, turn your thermostat way up and see if the furnace lights. The fan will probably restart in a minute or so as a normal function, heat or no. If the furnace does not fire, Let me know and I'll tell you how to check that switch that was replaced.

I have a Goodman GMP125-5 furnace. A year ago, my circuit board was replaced by a repairman. He also replaced the heat exchanger, because he said it was cracked. It worked great until about a month ago....

it would sound like the pressure switch is not working you can take off ther tubes and by hand put a small drill bit in the and clean the switch , some times this works , on some you can jump out the switch and try and fool it in too working

I just had a 2 stage furnace put in and a 1 stage thermostat. The thermostat has been changed three times, but the furnace still won't come on as it's programmed to do. Where do you think the problem lies?

A single stage thermostat can be used on a two stage furnace, but there is a dip switch on the furnace computer board that will need to be changed, the directions are in the installers installation guide.
Also not knowing what type and brand of thermostat you have, leaves me guessing, some higher end thermostats have intelligent recovery, if you set it to 70 degrees, at 7 AM, it will try to have the temp to 70 by 7AM, so it could be coming on, even 2 to 3 hours early, depending on the temp. Most of them have a 7 day curve, so it takes awhile for them to adjust, this feature can be turned off, you will again need the installer's install manual.
I hope this has helped, please rate me and also get back to me if you have any more questions.

Are all your supply vents open? The furnace may be oversized or have a air blockage. Have you always kept the filter changed. Newer heaters need the ducts sized right. If the new unit has worked great in the past then it's probally not the duct work.

Lennox furnace 17 yeanrs old. flame comes on and the shuts down sometimes right away some times in a few minutes. We have the furnace go down to 58 at night. It takes all day to get back to 67.

Sounds like a dirty flame sensor.
Also 9 degrees is a large swing to recover. Most specialist will advise no more than a 5 degree set back, otherwise recovery time eliminates any savings you may achieve.

Hi, sometimes depending if the unit is an up flow or down flow that depends where they put the filter.If you don't have a return grill in the ceiling, then it would be in the bottom of your furnace. I am sure its hard to remove as it is new, but i am sure it is there.Sometimes there is a grill on the lower wall beside the furnace they could have put it in. They may not have installed one? Good Luck, Sincerely, Shastalaker7
