Why cools the ac only 1 hour full power and never reaches the set-point temperature ?


check that all the doors and windows are closed as ac units do not work well when trying to cool the world
is the ac unit too small for the room size
I suspect that because it is working the problem is outside the ac control
is the inside fan working and blowing out cold air

Air Conditioning Programmable Thermostats - Great for Heating and Cooling


Programmable thermostats contribute to overall system performance, maximizing energy savings while providing complete comfort control. They also allow flexibility to homeowners because they can be programmed to match their lifestyle. Programmable thermostats save energy by turning down the cooling and heating system at night or at times when your home is typically unoccupied.


Did you know that properly using a programmable thermostat in your home is one of the easiest ways you can save energy, money. Homeowners can save about $180 a year by properly setting their programmable thermostats and maintaining those settings. They can achieve significant energy and money savings that are possible through the proper use of your programmable thermostat. Programmable thermostats do two things:
(1) Compare the thermometer reading of a room's temperature to the "ideal" thermostat temperature you select.

(2) Give start-and-stop commands to the heating or cooling system in order to achieve an indoor temperature that is as close to your "ideal" thermostat setting as possible.


Your savings will largely depend on the length of your energy saving program periods and the temperatures set. For example, an energy saving period of 10 hours with the temperature set back 10° will save more than a 5 hour energy saving period with the temperature set back 5°. By maintaining the highest or lowest required temperatures for four or five hours a day instead of 24 hours, a programmable thermostat can pay for itself in energy saved within four years.

A programmable thermostat will keep you and your home comfortable while you are there to enjoy it, and will change the set point at programmed times to an energy savings level when you are not home. The precise temperature control of a programmable, energy-saving thermostat saves wear and tear on high-efficiency heating and cooling equipment by properly cycling the equipment. A programmable thermostat will keep you and your home comfortable while you are there to enjoy it, and will change the set point at programmed times to an energy savings level when you are not home.


Controlling your heating more effectively could save you up to 17% on your heating costs. In fact, during the winter you can save about 3 percent of your heating costs for every degree you lower your thermostat. Begin lowering your heating bill immediately with the pre-programmed 7-day schedule, or modify the programming to suit your lifestyle. By delivering the heating or cooling when you need it, and optimizing temperature for activity, sleep and times you are away you can maximize your comfort level and save energy.

Honeywell thermostat "In Recovery" Message?


In recovery only shows on programmable stats. It refers to the adaptive recovery when using the programming. Over time the stat will learn how long it takes to cool or heat to the programmed set point. For example, if during the day the programming is set to 80?, and at 4:30 the programming drops to 76?, if it takes 2 hours for the temperature to reach 76?, it will learn that it takes 2 hours and eventually it will start turning on at 2:30 so that at 4:30 the temperature is satisfied instead of at 6:30, at which point it is no longer in recovery

PA10JA048-H Payne Air Conditioner outside unit not working but is getting power from circuit breakers. Need help.


Please read through the following and see if you can pin point the problem. Write back if you need with more information and I'll walk you through what ever you find. Roger
Due to the many different questions I see about Air Conditioning, I am including this overview to help us better understand each other for trouble shooting. A basic air conditioning system has a Thermostat, Air Handler or Furnace Fan and a Condensing unit. In a split system, the condensing unit (Condenser) is separate from the furnace and usually in the back yard. When working properly, it blows hot air. It connects to the cooling part of the system by 2 copper lines. One large line and 1 small line. The part that cools the house is the "Evaporator" and is usually on top of the furnace inside the square metal box (Plenum). When the Air Conditioner is running, the large copper line should be cold and the smaller line should be warm. Common signs of low refrigerant are that both lines are the same temperature and/or frost or ice has built up on the large line at the condenser. The thermostat will normally display room temperature on till it is touched to change the setting. It could have a "Span" setting as well as times and temperatures. The operating "span" of MOST residential thermostats is 40 to 90 degrees. That means you can set it as low as 40 degrees and no higher than 90 degrees. It probably has a fan switch also. When in the "ON" position, the fan will run constantly, 24 / 7, but the condenser will still cycle on and off as needed to keep the house at set point. If you have a suggestion to include in this paragraph, please let me know.

I have a Altech ALTHCO14 - i want it ON all the time - can i do this? Or what is the simplest way to have a constant temperature of about 20 degrees. Thank you.


hi i am also having some problems finding the instructions for this model of programmer as ours have been lost. What confuses me is that there are only 5 set point times per day, i would have thought there would have been 6, ie, on time and off time - at three different periods throughout the day. I think what you need to do is just make your first set point time 0.01am and your next set point time 23.59pm and do that for each day, you automatically have to scroll through the temp setting anyway so just bump that up to 20 deg thats what you want.
Also I just discovered (thankfully as this is in a building of ours currently unoccupied) that when you have frost mode on, ours is set to 5deg, the normal programme doesn't run? I thought frost mode was a protection device so that you could have your timer set up normally but if in between times the temperature drops below 5deg then the boiler automatically comes on to maintain at least 5deg. hope this helps and please if you found instructions on line somewhere email me the link to dlmc@btinternet.com bye

I have the problem of the airconditioner showing a temperature on the remote and increasing the temperature by itself on the actual unit. I don't have a book to check the error as it was a unit that was...


What might be happening is that when you set the temperature with the remote, the unit will display the setpoint. After a certain amount of time it will revert to displaying the room temperature rather than the set point. Does the unit still work after the temperature display increases? I would recommend setting it on 23 degrees.

I have a new Goodman GasPack heating and A/c unit. I turned the a/c on for the first time this year and I'm having problems with the theromastat. When it is set at any set point say 77 the a/c comes on...


If the space temp is (example) 72 degrees and you set at 80 degrees the unit should not come on. The A/C comes on when the space temp gets 2 degrees above setpoint temp. What type of tstat was installed digital or old syle mechanical. I'm leaning more towards a short in tstat wiring

Thank you. there are some other signs i don't know about.


The black triangle means AUTO, means the fan speed adjust by itself from high-mid-low speed depending in room temperature but the unit is cooling for this function the same COOL mode. Plasma is in the remote control but it never mention in the manual.
If the unit dont cool check your temperature setting and mode setting it should be in cool mode and temperature setting should be 18C. But if still don't cool check some error code like blinking light at the indoor panel check how many blink appears to get the correct error code.. If the light is blinking 3 times it means that the room air or coil sensor is defective.

Temperature varies 13 degrees around setpoint on aux heat


I don't have the book for this particular unit but, check the sequencers that control the electric heat mode, as the regulator heat pump works good. The part may have a time or temperature delay that is too long for you. Also if it has a remote thermostat, check the heat anticipate setting. You will have to check the installation manuel, but its usually .6 to .8, but I don't think that is the problem.
