Option 07 — Zoning
This selection should be set to On when the thermostat is to be used as part of a
zoning system. It is assumed that the zoning equipment will take care of time
guard and cycle timers. The minimum on time is still controlled by the
thermostat.
Default is OF (off).
Option 08 — Auxiliary Heat Lockout Temperature
This selection is available on heat pump systems with a valid outdoor
temperature sensor connected. Available settings are: Off, 5, 10, 15, 20, 25, 30,
35, 40, 45, 50, 55.

Outdoor temperature above which the auxiliary heat
is not allowed to operate (unless MODE is set to Emergency Heat). If room
temperature falls below 45
F (7
C), the auxiliary heat will be allowed to turn on
and will continue to run until demand is satisfied.
Default is OF (off).
Option 10 — Reversing Valve
This selection is only available on heat pump systems. “O” terminal can be
configured to be energized in either heating mode or in cooling mode, depending
on heat pump operation. “O” is used to describe a heat pump system that
energizes its reversing valve in cooling. “B” is used to describe a heat pump
system that energized its reversing valve in heating.
H — Reversing valve output (O/W2/B) is energized when HEAT mode is
selected.
