Option 34 -- Hybrid Heat Furnace Latch
This selection allows a Hybrid Heat system to finish a heating cycle using the
furnace.
On -- Once the furnace is on, it will finish the heating cycle with the furnace. If a
heat pump defrost occurs, the heating cycle will finish with the furnace.
OF -- The system will stage from furnace back to heat pump if heating demand
dictates, or 2 minutes after a defrost has ended.
Default is On.
Option 40 — Humidify Fan
This selection controls whether humidification can only be done when a heating
demand is present. If the homeowner turns humidification OFF, this configuration
operates as if the selection was set to OFF.
OF -- The humidity output will only energize when there is a humidity demand and
the heating equipment is energized.
On -- The humidity output and the fan will energize anytime humidification is
needed during heating mode regardless of the state of the heating equipment.
Factory default is OF (Off)
Option 41 — Variable Speed Blower
This selection allows the installer to select between a single speed or variable motor.
In a system with a two speed compressor (A2, h2, H2), if a dehumidification
demand exists and the compressor is energized for cool to dehumidify, cooling, or
both, and the system has a PSC blower (Option 41 = OFF), then both Y/Y2 and
Y1/W2 are energized.
