Carrier Performance A07048 Installation Instructions Manual page 40

Option 33 — Single or Two- -Piece Installation
This configuration allows the Thermidistat Control to compensate for the
amount of heat generated by the Thermidistat Control electronics to allow more
accurate sensing of the temperature sensor. The amount of heat compensation
will be different between single installation and two- -piece installation.
Range: 1P or 2P
1P — The installation is single piece.
2P — The installation is two separate pieces.
Default is 2P.
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.
Off - - The system has a single speed (PSC) blower.
