Hi All,

I have a 5-1-1 programmable thermostat, but it's driving me crazy.

I think it might be too sensitive. For example. If it is set for 21
degrees and the temperature drops to 20.9 to furnace cuts on. I have cast
iron rads (oil/hot water) so anyways the temperature drops to 20.9 and the
furnace cuts on and stays on until it reaches 21 degrees. This only takes
like 40 seconds or so. The 30-40 seconds later the temperature drops by .1
back to 20.9 then the furnace cuts on and so on and so on and so on.

Is the thermostat (Noma) too sensitive? I mena the furnacing cutting on and
off every 40 seconds is driving me crazy. You know the noise of the furnace
and all. To me it's just burning oil. The house is warm and could use a
drop or 2 before it kicks back on but every .1 drop in the temperatre is a
little mush.

This is my first time having a programmable thermostat. Is this normal. The
furnace is a Veismann and has been serviced recently and is actually only 3
years old.

Any advice or comments?

There sound be an adjustment for that. Look for anticipator or for a
degree spread adjustment. They are two different things, and I can't tell
which one may be set or functioning improperly.

Not really, not all of them have that adjustment.

JM Look for anticipator

An anticipator doesn't control the on temp it controls how quickly the unit
shuts off.

Yes, I guess they don't all have it.

I agree, but could that not be the OP's problem?

Nope, he says it is coming on too soon. I didn't catch the brand he put in
but if it is hunter or lux that could be the whole reason right there. those
cheapies usually cause quite a few problems.

I don't know, it seems if it was shutting down too early, it would then
have not supplied enough heat to keep it from recycling on.

In any case I think Turtle may have hit the right thing.

It's a NOMA 5-1-1 programmable thermostat. Oil/Hot water, cast iron rads,
Veismann furnace.

'An anticipator doesn't control the on temp it controls how quickly the

Indirectly . Actually, the anticipator determines how soon to start
another 'on cycle' . Adjust the anticipator so you get a 2 f. drop in
house temp before the next on cycle starts.

Wrong as usual, The heat anticipator causes the unit to shut down earlier to
help keep overheating down. the amp draw of the gas valve or electronic
ignition is run through a coil of wire wrapped around a card which acts as a
small heater. this small heater is right under the helicoil and causes it to
react a little quicker. you really need to get some training before you try
to work on this equipment.

This is Turtle.

You need to check the paperwork for the thermostat and see about the settings of
the thermostat as to being set up for heat pump, straight electric heat, or gas
heat. Some have switches on them that your suppose to set to burn different
fuels like natural gas or oil or Electric heat.

Now it sounds like you got it set for electric and your burning oil. When all
else fails -- read the instructions.

Are you sure that the problem is with the thermostat, and not some
problem with the furnace? Shove the heat setting all the way up to
90, and if you still get short 40 second bursts while the house
comes up to temp, then it's a furnace problem.

My programmable stat has a setting called "temp swing" and it is in
degrees. If I set the swing temp to 3 degrees and set my set temp to
70, the furnace will come on when it reaches 67 and shut off when it
reaches 73. Obviously, that's kind of extreme. I have the swing set to
"1" and I get a reasonable cycle.

I cant address your problem but can say short cycling is killing the
life of your Boiler controls and it never reaches its rated efficiency
on short cycling. My boiler runs for 1/2 hr Minimum and I will guess
total efficiency is not reached for 5-10 minutes. Short cycling takes
its toll on components rated for only so many cycles as all are in
design. Get a Pro out, get it set right, and understand operation of
what you have. A Pro will direct you.. Add up your cycles , per day -
year, then you may understand,
