Furnace (Air 

Conditioner) 

Cycles Too Fast or 

Slow (narrow or 

wide temperature 

swing) 

The location of the thermostat and/

or the size of the Heating System 

may be influencing the cycle rate

Digital thermostats provide precise control and 

cycle faster than older mechanical models. The 

system turns on and off more frequently, but runs 

for a shorter time. If you would like to increase 

cycle time, choose SLO for slow cycle in the 

Installer menu. (Reference menu items 

30, 32 & 

35.

) If an acceptable cycle rate is not achieved, 

contact your HVAC service person.
