The temperature in my home is always either too hot or too cold so I suspect the
programmable thermostat is not set correctly.
The owner's manual mentions "set point" but it's not clear what that means.
Is the "setpoint" the temperature at which the furnace (or air conditioner)
turns on or turns off?
The set point is the number on the thermostat you see. It is the number
that you put the dial on or if digital , the number you adjust up and down.
If programmable, you probably have several Set Points. That is the
temperature you want the house to be at the time you want.
Say you leave the house at 8:00 every day, you may want to have the
setpoint at 65 deg. If you come home at 5:00 then about 4 or 4:40 you want
to move the set point back to 70 deg so the house will be at 70 deg when you
get home. Then about 10 at night you may want to have the set point at 68
deg for sleep. Then about 5 in the morning you may want to have the set
point at 70 so the house will be warm when you get up.
You will have to adjust the set point to match the temperature you are
comfortabel at. Give the house an hour or two for each degree you move the
set point while trying to find a confortable temperature while you are in
I'll repeat my earlier question:
On my thermostat, there's a "COOL" and a "HEAT" mode for "MORNING", "DAY",
"EVENING" and "NIGHT". In the middle of winter, I don't want "COOL". How do I
programming it for "HEAT" only?
Since you are too stupid to have a name how could we expect you to R T
Please try and understand your own problem before asking stupid

John, this person asked the same thing about 3 or 4 months ago here. I
remember his first question was exactly the same question as before.
Even if I took it seriously, I can't believe a person wouldn't give
the make or model of the thermostat to help others return the help. Oh
well, I guess he needs attention and this is how he gets some. I
hope he learns how to use his thermostat or he might have one cold

Unfortunately, with the decision to purchase a programmable thermostat
comes the obligation to learn how to program that new thermostat. It's
like buying a clock radio and going online to find someone to help you
figure out how to set the alarm time on it.
Every digital thermostat is different, and you need to find a 1-800
number in the literature that came with it to determine how to program
Also every thermostat, whether digital or analog will have an "heat
anticipator" setting that needs to be set. A heat anticipator in an
analog thermostat is nothing more than a small electric heater that
fools the thermostat into thinking the room is warmer than it really is.
The reason for having a heat anticipator is that some forms of heating
have a long residual heat time. For example, cast iron baseboard
radiators will continue to convect heat into the room long after the
boiler shuts down. The purpose of the heat anticipator is to heat the
be-metallic coil inside the thermostat to fool it into thinking the room
is warmer than it really is. That shuts off the boiler early so that
the temperature doesn't overshoot the set point be as much as it
Another reason for having a heat anticipator in a thermostat is that the
thermostat is typically centrally located in the house or zone being
heated, whereas the radiators or heating ducts are located around the
perimeter of the house or zone being heated. If the boiler were to
continue firing until the temperature at the thermostat was at the set
point, the room temperature between the thermostat and the perimeter of
the house or zone being heated would be well above the set point.
Consequently, the heat anticipator is set to shut the heating system off
early so that the average temperature in the house or zone being heated
fluctuates about the set point.
Now, your literature will tell you to add up all the amperage draws on
all of the thermostats zone valves and everything on the 24 volt AC loop
the thermostat is on to determine the heat anticipator setting. As of
now, I have yet to find anyone who can explain why the heat anticipator
setting should be equal to the current draw of the thermoatat 24 VAC
loop. You're best bet is to simply set the heat anticipator setting
lower if you find that your furnace is cycling too frequently, and to
set your heat anticipator setting higher if you find too long a time
between your furnace cycling on and shutting off.
[When I ask for help, I expect the responses to be helpful (not insulting)].
I have a Totaline Model P474-1035 Programmable 5-2 day Digital Thermostat.
In the owner's manual, in the "Normal Operation" section, the "Manual Thermostat
Operation" instructions say to:
1. Set the program switch to "OFF".
2. Set the mode switch to "Heat" or "Cool". (Since I don't need cooling in the
winter, I've set the mode switch to "Heat").
3. Set the fan switch to "On" or "Auto". (Since I don't want the fan to run all
the time, I've set the fan switch to "Auto").
4. Use the "Up" or "Down" buttons to set the desired temperature. (I've set the
desired temperature to 78 degrees)
If the current room temperature is 64 degrees, shouldn't the heat come on
immediately or is there a built-in delay?
That seems a lot more clear as to what your question is etc.
Since you have the thermostat set up to operate manually, the heat should
come on if the room temperature is 64 and you set the desired temperature to
78. There could be some delay in the heater coming on depending on what
type of heater you have etc., but the delay shouldn't be too long -- I'm
guessing a few minutes at the most.
If the heater isn't coming on, something else is wrong. Does your heater
have a little red indicator light on it that is either staying on constantly
or is blinking? If it is blinking, watch to see what the blinking sequence
is -- such as 3 blinks, etc. Then read the instructions on the front of the
heater that says what the different blinking sequences mean.
