The number indicates how frequently the system cycles on and off to maintain the set temperature.
A higher number means the system is on and off for shorter amounts of time, a lower number means
longer on and off times. When these settings are set to match the system type, the thermostat controls
temperature more accurately.

Wiring Notes
Conventional system
Alternate wiring (conventional systems)
Remove metal jumper connecting R and Rc only if
you must connect both R and Rc wires.
If your old thermostat had both R and RH wires,
remove metal jumper. Connect the R wire to the Rc
terminal, and the RH wire to the R terminal.
If your old thermostat had only 1 C or C1 wire,
connect it to the C terminal. If your old thermostat
had 2 C or C1 wires, wrap each separately with
electrical tape and do not connect them.
Heat pump

Leave metal jumper in place, connecting R & Rc terminals.
If your old thermostat had both V and VR wires, stop now and
contact a qualified contractor for help.
If your old thermostat had separate O and B wires, attach the
B wire to the C terminal. If another wire is attached to the C
terminal, stop now and contact a qualified contractor for help.
If your old thermostat had Y1, W1 and W2 wires, stop now and
contact a qualified contractor for help.
If L terminal is used, C terminal wire must be connected
