Just install suzka09/slkka09 with mrch1 remote. The remote cool setting only goes down to 67 degrees. Can you help? I'd like to set it to 60 degrees. Confirmed that the min setting is at 50 degrees but it won't let me go down below 67.

My thermostat is set on 68 degrees and it shows room temperature is 68, but the furnace still kickson, Honeywell said it has a 1 degree difference. so what's the problem then?


Yes there is a one degree tolerance, in fact my heater just kicked on and it is set to 67 and the inside temperature reads 67. It is also a Honeywell.

Why can't I lower my honeywell 8500 below 67 on cool?


With a two story house you have to be aware that cold air flows downwards so any cold air coming from an ac unit will flow downstairs( normally down the stairway) so unless you can close off the down stairs then the up stairs unit will be cooling downstairs as well. Ac units have a thermostat located in the air intake and it cools until the cold air has risen to that point. In effect the space above the ac unit will be hotter than the floor. Knowing how they work ,you can see that the upstairs unit will never reach the set temperature because the cold air is continually heating from the house and will never get to the top thermostat.
So your solutions are
1-- fit controls that restrict the cold air from leaving the upper floor (Doors)
2--don't run the upper ac unit unless you are living up there (waste of money
)3 place an ac in each upper room and keep the room door closed

Wont allow me to set thermostat below 73 degrees?


You never said what type and model of thermostat you have....... If you have a digital stat You may have to lower the HEAT setting below 67 degrees if you want to set the AC to 70 degrees. If the thermostat has an Auto feature then it has to have a 3 degree differences between heating and cooling. On the newer models it does it automatically if you lower the Cooling setting it will lower the heating setting......It this doesn't help repost with more information so I can help you better....

You didn't include a model number, so it's hard to know for sure - but I'll take a stab at this one. Many of these t-stats have a programmable offset to reduce "hunting". This can be as little as 1 degree or more than 2 degrees.

This means if you set the offset to 1 degree and the room temperature to about 65 degrees, the furnace will heat the room until the t-stat registers a rising temperature of 66 degrees. The furnace shuts off and will not turn on again until the t-stat registers a falling temperature of 64 degrees. The average is 65 degrees, and prevents the furnace from starting and stopping numerous times instead of just once with the 1 degree offset.

You can further reduce the number of furnace start and stops by increasing the offset to 2 degrees. This would work like this when the t-stat is set to 65 degrees and the room is cool:

Room Temp Furnace
63 On
64 On
65 On
66 On
67 On
68 Off

The room is now warm and heat or furnace is off. The room begins to cool like below:

67 Off
66 Off
65 Off
64 Off
63 Off
62 On

With a 1 degree offset, the room temperature varies +/-1 degree (about 2 degrees total). With a 2 degree offset, the temperature about varies +/ -2 degrees (about 4 degrees total).

Also, when the thermostat shut the heat off, the heat that was made is delivered to the space instead of wasted by sending outdoors - so the room will get a little warmer even though no fuel is being burned. The same holds true at the other end. When the t-stat turn heat on, fuel is burned, but there's little heat until the source has reached the optimum temperature and then the heat is delivered to the space.

I hope this helps & good luck! Pleas rate my reply - thanks!

Read your maunual. It might be normal. A 4 degree split in your set back heateing control is about normal. It is that way so you can turn your unit on and never really need to touch it again. When the temp goes up, cooling goes on. When the temp goes down, heating comes on.

This sometimes happens over time with some digital thermostats. The easiest solution is get a toothpick and hit the reset button. From there just set it as you normally would. That should solve your problem.

Hope this info was helpful to you. Good Luck!

Does the T8602C1095 have an anticipator that may need adjustment when the temperature set is exceeded, eg we set at 70 and it goes to 71-72 and then need to manually shut down system.


that is how they work. ther is a 1 to 3 degree variance up or down.it probaly does not kick back until 67 or68 degrees. a two stage furnace will keep a more steady temp.
