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.

What are the numbers on the metal strip on the inside of my thermostat from 1.0 @ the bottom too .2 at the top it has a bronze sliding clip with point on it I moved it and not sure if my temp setting


You shouldn't be messing around inside the thermostat. You have now changed the setting on the heat anticipator.This control is used to set the heat, so the heat shuts down before and in anticipation of the heat reaching its set point so it doesn't overshoot it. This thermostat will have be to reset by a pro. I believe it would be cheaper to just buy a new digital thermostat.

On the thermostat the "filter"


Thermostats used in homes sometimes have a timer built in which will remind you to change your furnace filter. Most of them can be adjusted or disabled. The thermostat has no way of knowing whether the filter is actually dirty, it just reminds you every so often by flashing "filter" on the display.

It is possible to reset the timer, or adjust how often it appears, or disable it completely. Exactly how to do that depends on the make and model of your thermostat. Often, it is simply a case of holding two buttons at the same time for a few seconds.

As to why the furnace doesn't come on, there can be many reasons. The problem likely is not the "filter" flashing on the display of your thermostat. Try resetting the breakers that service the furnace unit itself. Make sure that the thermostat is set to "heat" and the setting is turned up. If the thermostat uses batteries (most do these days), replace them.

If this doesn't work, the following information will be helpful to get the furnace running again:
Brand
Model number
Age of furnace
Location in home
Brand and model of thermostat

All I need to know is this: The Chronontherm III died (my house is 20 years old and I believe it was original to the house) and I need a new thermostat. Can I replace the Honeywell Chronotherm III...


Hi,

Yes, you can replace with that...just make sure that you mark the wires BEFORE removing them...so you can place them on the same terminals on the new t-stat...

Here is a list of each common terminal and what their commonly used for. Also listed is what colors are commonly used. NEVER ASSUME these are what you have. Verify all your wires by following each to each piece of equipment. This will help you to be able to match your equipment with the terminal.

Here is the rest of the tip that I wrote...

I have several Mitsubishi Electric wall thermostats in my home. They operate two R-410A Mitsubishi CITY MULTI PUMY S-Series Systems. The thermostats will not go below 68 in some rooms and 70 in others....


If there is any option in your thermostat "Limit temp function" press 5 seconds continuously. Then reset it as you like.

Second way of trying is remove batteries/power from your thermostat and reset it. Now you can set as u like.
