NOTES - Heat Pump Systems
[1] Optional 24 Volt AC common connection.
[2] O (cool active) or B (heat active) is selected in
the Installer Settings menu.
[3] Install a field supplied jumper between the
W2 and W1/E/W3 terminals if there is
no separate emergency heat relay installed.
[4] If the L terminal is used, the 24 Volt AC common
must be connected (C terminal).
[5] If a separate emergency heat relay is installed, the
W1/E/W3 terminal should have both the auxiliary
heat 1 relay and emergency heat relay connected.
[6] If a separate emergency heat relay is installed, the
W1/E terminal should have both the auxiliary
heat 1 relay and emergency heat relay connected.
Provide disconnect and overload protection as required.
