OF (off) - function is disabled. Auxiliary heat is allowed to operate whenever sufficient demand for heat is available.

Option 09 — Heat Pump Lockout Temperature

This selection is only available on Hybrid Heat systems. A Hybrid Heat system is selected via the Option 1 Equipment Type configuration. Configurations settings are: OF (off), 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55.

OF (off) — the heating cycle will always start with heat pump heating.

5-55_F — the outdoor temperature below which heat pump operation is not allowed.

When emergency heat mode is selected only auxiliary heat will operate. 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.

C — Reversing valve output (O/W2/B) is energized when COOL mode is selected.

Default is C.
