Programmable Thermostat

Programmable thermostats save energy by permitting occupants to set temperatures according to whether the house is occupied. These thermostats can automatically store and repeat settings daily with allowance for manual override. By eliminating manual setback, which is easy to forget, they allow the setting of more comfortable temperatures in the morning before occupants wake. Temperature setback can be adjusted for both heating and cooling seasons.
Programmable thermostats can be set to adjust the temperature setting according to a user's schedule. These thermostats typically have a digital interface that allows more precise temperature control and a wider range of options or features.

Programmable thermostats typically offer a numbe of programming options:

  • Daily programming that allows one schedule to be used each day
  • Weekday/Weekend (5/2) programming that allows adjustment of timing for setbacks with different settings for weekdays and weekends, and with 5/1/1 programming that permits separate schedules for Saturday and Sunday
  • Full seven-day programming that permits a different setback schedule for each day of the week.
  • Other special features depend on manufacturer and model and may include the following:
  • Vacation Override, which allows temporary override of the programmed settings.
  • Keyboard Lock, which prevents unauthorized changes to the preprogrammed settings.
  • Low Battery Indicator indicates whether the battery used to hold the programmed schedule is low.
  • An Energy Monitor that can keep track of how many hours the HVAC system has run for any selected time period
  • An Auto Season Changeover that automatically provides heat or cooling at the onset of the heating and cooling season
  • A Filter Change Indicator that goes on after a pre-set time period to remind when it is time to clean or replace the filter

Different types of heating/cooling systems may require different types of programmable thermostats. For example, heat pumps require programmable thermostats that minimize the use of less efficient auxiliary electric resistance heating. Only a few companies manufacture line-voltage setback thermostats that directly control 120 volt or 240 volt line-voltage circuits connected to electric baseboard electric heaters. When purchasing a programmable thermostat, it is necessary to insure the thermostat is compatible with the HVAC system.

What you just read on this page above you can easily find on a lot of websites, but almost nobody tells you about another one very important feature that it can let furnace to rise temperature for one degree above set point and it will start the heating cycle when there is one degree below it. Let’s find out why it’s important and how it can save you some energy and of course money:

If you have regular mechanical thermostat you probably paid attention how often your furnace kicks-off. Every time when thermostat is calling for heat the furnace use a lot of gas to bring temperature in the heat exchanger to the point when the blower starts up. Therefore, here is a conclusion: you need a programmable thermostat to save some money.

I have a Goodman GMH950703BX 69,000 Btu 95 % Furnace. My question is I normally set the Thermostat at 67 and it seems like the air is not that warm when you feel down by the vent, but if I go out side or don’t pay attention to it went it kicks on the house feels fine. The other question I have is My bedroom is above the garage and it seem that at 67 the room is cold but at 70 the room is fine is there a way I can program the furnace to burn at the high temp so I can run at 67,or is there not that big of a difference from 67 to 70 in my bill !

Furnace may not be set up right. As in was its input rate checked in both stages, and the blower adjusted properly? There is no way to make it go to second stage right away, 10 minutes in first then second stage is built into the board.
Probably 5 to 10% increase in heating bill between 67 and 70.

You said 10 minutes and the second stage should kick on. When my furnace kicks on it runs for 6 to 7 minutes and it stops, should it be running longer if so should I have someone come out and take a look at it.

It could be that the CPH is set to 4, or that the furnace is slightly over sized. That it’s not running longer. Of course at mild outdoor temps, it won't run long enough to go to second stage.
What thermostat do you have, and what size house.

Your house is heating up fast enough that it does not hit the 10 min mark to go to 2nd stage. Will go there on real cold days or if you have a true 2 stage thermostat installed. Look on the circuit board to see if there is a wire attached to W2. If not then you have 1 stage and timed switch over. Higher temp runs it longer and progressively gets the further away areas warmer. If it was going to 2nd stage the fan would blow more heat faster there. With a 2 stage stat it needs to drop more than 1 deg F B4 it switches to 2nd so in mild weather the furnace can probably keep up with the load on 1st stage and you just need to get used to it. High efficiency units supply air at 130*F which is 20* lower than the older units and feels different but you get used to it. 2 stage thermostat needs another wire from stat to furnace installed.

The Goodman GMH can't be controlled by a 2 stage stat. Goodman made it that only the furnace control board controls the staging. They decided to cash in on the customers that want the comfort of 2 stages, with a low price. But the customers don't know that they don't get the comfort that 2 stages are suppose to provide, because the board is crippled, to make it cheaper.
