On initial power up of the thermostat (each time 24 Vac power
supply is removed and re-applied) there is a delay before any
operation is authorized (fan, cooling or heating). This can be used
to sequence start up multiple units/thermostat in one location.

Off: no room frost protection

Maximum occupied and unoccupied heating setpoint adjustment.
Heating setpoint range is: 40 F to 90 F (4.5 to 32.0 C)
Minimum occupied and unoccupied cooling setpoint adjustment.
Cooling setpoint range is: 54 F to 100 F (12.0 to 37.5 C)
Adjust the proportional band used by the thermostat PI control loop.
CAUTION
Note that the default value of 2.0 F (1.1 C) gives
satisfactory operation in most normal installation cases. The
use of a superior proportional band different than the factory
one is normally warranted in applications where the
thermostat location is problematic and leads to unwanted
cycling of the unit. A typical example is a wall mounted unit
where the thermostat is installed between the return and
supply air feeds and is directly influenced by the supply air
stream of the unit.
