EMER 
(heat pump only) 

If you set your thermostat for HEAT PUMP with auxiliary heat, the EMER 

function is available on the Manual screen. If you touch EMER, it displays 

EMER|ON. You heat pump is disabled and auxiliary heat is your sole source 

of heat. This manual override stays active until you toggle EMER off. 

Auxiliary heat is more expensive than the heat pump, so use EMER only if 

the heat pump cannot keep up or is defective.
