2441TH thermostat mode button

[JSchumann]

My wife hits mode button to look at the screen (turn on light) but it changes mode from heat to cool.....Is there a way to disable that until I need it (season change)?

 

Thanks,

John

No buttons can be disabled. Try a slightly less convenient two-tap solution. Tap up, then down (or down, then up). Or just leave the display on.

How do you get display to stay on?

Sub-Mode 01 in the on-line Owner's Manual.

Actually, you can disable the buttons.  It is in the manual, it is the same set of menus that you use to change the light settings.  But it disables all the buttons, you can't just pick a button.  While the buttons are disable, hitting any button will still turn the light on.  Once disabled, you would need to make changes to your thermostat from ISY or from some other remote control method.  The buttons can be re-enabled using the same method that disabled them.

Ok, This is bizarre.  My thermostat in that area is set to 64 and temp always stays at 64.  When I adjusted the light mode to always on, the actual temp showed 66 and stayed there.  I assume the screen generated enough heat to make the thermostat temp sensor say it was 66...so heat never came on.  Set the light mode back to 10 sec and it is working again.

All smart thermostats have this problem, more or less. The stat companies do not like to admit it, though. They all have some problem and until the electronics become more micro powered or as many have done now, offered remote sensors to get the sensing away from the heavy heat generating electronics. When you open up any stat from a company with more than a toy manufacturer experience, you will see reflective foil, and/or insulation used in an attempt to isolate the sensor from the electronics.

 

Some stat companies have tried to compensate for the electronics heat generated by offsetting (mis-calibrating) the readings from the sensor. This works until a slight breeze comes along and takes the residual electronics heat from the sensor away. What you get now, is a differential On/Off of 4, 5, 8 degrees creating waves of heat and cold in the heated area of the stat. When the furnace runs the stat "feels" the fan draught, cooling the sensor, and the furnace runs too long, making any differential setting inside the stat a complete waste of setting menu programming. I have experienced this on about 4 brands of stats now.

 

BTW:Never go by the displayed temperature on the stat front. The sensor reflects the compensated temperature the electronics goes by and can be many degrees off of a good accurate sensor (only) placed beside it at the same distance from the wall. Every brand does this out of the four I have installed in the last two years.... Honeywell, Venstar, Tekmar commercial.  Insteon? I never look at the two I have anymore....mostly toys only good for emergency heat, ISY input metering, humidity but never home comfort without needing  a sweater on and off 3-4 times per day.
