Heating:
The fan speed for the heating cycle is
selected by adjusting the HEAT tap (see
FIGURE 2) according to TABLE 6.

ECM Fan Notes
1.
Fan only = 50% of max speed
2.
Dehumidifying speeds
i)
First stage dehumidification =
67% of max speed
ii)
Second stage dehumidification =
45% of max speed
3.
Green Light will blink once per every
100 CFM
4.
Dehumidification terminal is BK. There
must be a constant voltage to this
terminal, and when the voltage is
dropped then dehumidification mode
will begin.
Fan wiring notes:
1.
If only one stage of cooling is used then
jumper Y1 and Y2.
2.
If unit is not heat pump capable then
jumper O and Y1.
3.
If no humidistat is used then jumper BK
and R.
4.
When only one stage of heat is used
jumper W1 and W2.
Reheat Coil Refrigerant Piping
The reheat coil is shipped already
installed on the leaving air section of the
air handling unit. A liquid receiver is
shipped loose with the unit for field
installation.
(See matching condensing unit
installation, operation, & maintenance
manual to determine acceptable refrigerant
line size.)
1.
Run a hot gas line from the outdoor unit
and connect it to the inlet of the stub-out
on the reheat coil.
a.
For vertical (up-flow) units.
The
inlet connection is the left stub-out
when facing the front of the unit.
Connect the hot gas line from the
outdoor unit to the left stub-out.
Connect the check valve (shipped
loose) to the right stub-out in a
direction so that the refrigerant flow
is leaving the right side of the coil.
Be sure to not block access for
service of the air handling unit with
the placement of the check valve.
b.
For horizontal discharge units.
Connect the hot gas line from the
outdoor unit to the upper stub-out
connection of the reheat coil.
Connect the check valve (shipped
loose) to the lower stub-out in a
direction so that the refrigerant is
leaving the bottom side of the reheat
coil. Be sure to not block access for
