Remote time bypass input from usually from another device.
Bypass is a method to command unoccupied override over the
network from another controller. The other controller does the
bypass timing. nviBypass can be used to place the T7350H into
temporary occupied mode. This mode will bypass the time of day
occupancy schedule in this device.

Demand limit duty cycle load shed command from a network
device.
When a shed request is received, the thermostat "bumps" the
control set point up for cooling and down for heating. The amount
of the "bump is a user set point selection. The shed state remains
until a DLC restore command is received or network
communication is lost. When the unit transitions from shed to
restore, the set point is ramped back to the original set point over a
period of 60 minutes. The control only sheds when the thermostat
is in the occupied mode.
Value:
0: No load shed being called (mains power up or failure detect
value).
1 or other values: Call for load shedding.
Auto Fan switch (last in wins).
value = 0, state = don't care:
Fan is On.
value = Don't care, state = 0 or -1:
Fan is On.
Value = 0.5 - 100: state = 1 or greater:
Fan is On when there is a call for heat / cool.
Failure detect and mains power up value: No change from
previous value.
