I switched the thermostat to heat and nothing happened. it set at 68 and it was 63 in the house, i waited and nothing happened. i turned the fan switch to on and the fan works. i switched to cool and lowered the setting and it kicked on. any idea why the heater won't kick on?

Instructions1 On nearly every Honeywell thermostat, the heat setting can be increased by simply pressing the HEAT option or AUTO and using the arrow keys to adjust the setting higher or lower until the desired temperature is reached. 2 To set an automatic heating schedule for Wake, Leave, Return and Sleep, press the SCHEDULE button, then EDIT. 3 Select the current day and use arrows to select the time and temperature for Wake. For example, if you typically awake for work at 6:00 a.m. and want the heat to come on, use that as your Wake time and adjust the temperature to suit. 4 Select the day and use arrows to select the time and temperature for Leave. Since you will be leaving the home empty for several hours, this setting will allow the thermostat to lower the heat until your arrival back home. 5 Select the day and use arrows to select the time and temperature for Return. This is the time and temperature that you will choose for returning home from work and may want the heat on to warm the house for your arrival. 6 Select the day and use arrows to select the time and temperature for Sleep. Set the time you normally go to bed. The thermostat will automatically adjust itself to your selected temperature at that time. Thanks
Hello,Good job with description.Something is keeping the condenser off(saftey).Do you have an emergency heat setting on the therm.It will run electric heat strips only until service can check it out.Very rare that the disconnect switch (black box) is it.Need electrical meter to prove it out.
the thermostat sends a signal to the circuit board. Not knowing anymore than I do about your heater or furnace I would suggest that that is a good place to start. Any limit or safety switch wouldnt coincidentally shut off the heater when it reached the set temp.
You did not make it clear if the thermostat is a programmable unit or not. I am wondering if the thermostat is not set on the correct heat anticipation setting. A heat anticipater is a small heater that helps the thermostat turn off before it over shoots the desired temperature setting. If the thermostat is set for a 5 degree setting, it will turn off at 63 degrees if set at 68. If the anticipater was set at 1 or 2 degrees, it will shut off the heater at 66 or 67. Newer thermostats will only allow the thermostat to cycle 6 times per hour so if you never reach the desired temp, you have to wait 10 minutes before it will allow a call for heat. Check the installation instructions to see if there is a setting where you can get the anticipator temperature closer to your set temp. Good luck.
They do that sometimes as a timing feature when going from heat setting the to cool setting or vise/versa. It should not do that when the thermostat is off and then you switch it to cool. Make sure the batteries in the thermostat are fresh. And make sure the thermostat is fully seated on the housing. Also check the wires are fully inserted into the connections on the thermostat housing and the wiring is correct.
you have a circuit board acting up. Try keeping the fan in the "On" position. It will keep the blower on all the time but it may work. There is a built-in delay not allowing the unit to come on after you reset it with the thermostat, wait three minutes or so to see if it comes back on. I still suspect a bad circuit board.
