Extra Room Power Heat Duct
SKU 98500769
Special Instructions for 864 ST
The 864 ST has a removable cover plate shield below the heat duct connections. This allows more heat
to be routed to the power heat ducts (see below for details). Otherwise the heat duct is installed the
same as an 864TRV (one heat duct kit maximum, manually-controlled on/off operation – see wiring
diagram below).
