Why is my thermostat stuck in heating mode with no cooling option?
The operating menu on the thermostat lacks a cooling setting entirely, offering only heat and fan options that fail to lower the indoor temperature. This leaves the resident unable to restore cold air or change the stuck heating cycle.

“Tried finding where the cold air option was but couldn't find it and neither could I find anything on the internet that looks like what I have.”source ↗
“Operation Mode only gives me the options of "Heat" or "Fan", when I select Fan it'll take me back to the main screen with it saying Fan above instead of Heat without doing any change to the air blowing out.”source ↗
“Has anyone had the EcoNet room-temperature reading actually get stuck?”source ↗
“EcoNet stayed stuck at 71°F while an independent thermometer was reading almost 69°F. The system kept cooling.”source ↗
“Today the opposite happened with heating. Setpoint was 69°F and EcoNet stayed stuck at 69°F while the independent thermometer was almost 71°F.”source ↗
“The reading seems to occasionally stop updating during an active heating/cooling call, then refresh when I manually change something.”source ↗
