INTRODUCTION
These instructions cover the installation of a wall thermostat
(included, P/N 33CSSN2-MH) and the installation of a second
fan speed control relay inside the unit control box (of an RC or
RP unit), to provide two-speed fan control from file wall ther-
mostat. See Fig 1.
The two-speed fan control kit provides full fan speed con-
trol of the PTAC (packaged terminal air conditioner) unit from
the wall thermostat (included).
WALL THERMOSTAT
(P/N 33CSSN2-MH)
Disconnect all power to unit to avoid possible electrical
shock during inst;d lation.
INSTALLATION
NOTE: This kit can only be installed on w_dl thermostat
units (RC or RP models).
Prepare Unit
l. Check to be sure the unit is off and power to the unit is
disconnected.
2. Remove the unit's front panel by grasping it firmly nero
the bottom of both sides, then pulling panel forward and
upward to release magnetic latches and pmtition hooks.
Install Second Fan Speed Control Relay
I. Remove the terminal access cover and save. See Fig. 2.
2. Open the control box by removing the 2 control box cov-
er screws shown in Fig. 2. Swing the cover down to open.
Save the screws.
3. Attach the relay assembly to the 2 holes in the right
side of the control box as shown in Fig. 3. using two no. 8
x 3/_in. screws included.

11. Dross the wires using the wire ties provided.
12. Close file control box door and secure it by m-attaching
the screws saved earlier (take care not to pinch any of the
wiles when the control box cover is closed).

Right Side of the Control Box
Wire in Second Fan Speed Control Relay
1. Relnove the gray fan speed selector wire by disconnect-
ing it from the J2 terminal next to relay K3 on the PCB
(printed circuit board) and the fan speed selector switch.
See Fig. 4.
NOTE: The gray wire will either be connected to a rotary fan
speed selector switch on top of the control box OR a rocker fan
speed selector switch (as shown in Fig. 4) on the front of the
control box covet
2. Attach the gray wire from the relay assembly to termin_d
J2 next to relay K3 on the PCB. See Fig. 4.
3. Remove the black fan wim from the fan speed selector
switch (rotary or rocker) and re-attach it to termin_d 4 on
the relay assembly. See Fig. 4 and 5.
4. Remove the md fan wire fi_m the fan speed selector
switch (rotary or rocker) and re-attach it to termin_d 6 on
the relay assembly. See Fig. 4 and 5.
5. Remove fan speed selector switch.
For wall therlnostat units with a rot_uy fan speed selector
switch on top of the control box cover:
• Remove the knob and rotary fan speed selector
switch from the control box cover by removing the
2 scmws located under the knob shown in Fig. 2.
Discard the knob and switch.
For w_fll thermostat units with a rocker fan speed selector
switch on the front of the control box cover:
• Remove the rocker fan speed selector switch from
the control cover and replace with the plastic rect-
angular plug provided in the relay kit. See Fig. 2
and 6.
6. Remove the black wire from LI on relay KI.
7. Attach the black wim from terminal 2 of relay assembly
(with goal post termin_d) to LI on relay KI.
8. Re-attach the black wim (mmoved in step 6 above) to
open go_d post terminal of Ll on relay KI. See Fig. 4.
9. Attach the gmen ground wire from terminal 1of the relay
assembly (with piggy back male termin_d) to the gmen
ground wim attached to the PE termin_d on corner of the
PCB. Attach both wires back on to the PE termin_d on
corner of the PCB. See Fig 7.
10. The blue wim connected to terminal 3 on the relay assem-
bly is the second fan speed signal wim, for connection to
the thermostat. The blue wim has a quick connect/discon-
nect termin_d for easy disconnect and removal of the unit.
Route the blue wim out of the control box opening where
the terminal access cover was removed. See Fig. 8.

2. Remove the wall thermostat terminal block from the
PTAC unit, accessible through the terminal access open-
ing. See Fig. 9.
3. Wire wall thermostat to the terminal block removed in
previous step. See Fig. 10 and 11.
NOTE: Connect G2 to the blue wire for second fan speed with
the crimp-type wire joint included with the kit.
4. Re-install the fully wiled wall thermostat terminal block
to the PTAC unit through the terminal access opening.
See Fig. 9.
5. Re-inst_fll the terminal access covel: See Fig. 2.
6. Re-install the front panel.
7. Ifa rotary speed selector switch was removed in Step 5 of
the previous section, fllere will be a hole in file control
section of the front panel (where HI/LOW ftm speed was
selected). Cover file hole by replacing the existing control

Required Setup of Thermostat
I. Enter Advanced Configuration mode. See Fig. 13.
2. The only configuration item that must be changed is the
equipment type. For a heat pump unit, the equipment type
must be changed to 11. For a Heat/Cool unit, the equip-
ment type must be changed to 13.
IMPORTANT: Failure to configure the Wall Thermostat ]
with the correct type of equipment will result in improper I
operation of the thermostat and possibly, &nnage to the
PTAC unit.
Thermostat Operation
1. Refer to the instructions included with the thermostat for
basic operation and configuration. For additional infor-
mation on unit to thermostat wiring see Fig. 14 and 15.
2. Once the thermostat has been fully installed and config-
reed, test all operating modes and fan speed control.
NOTE: Set the thermostat to 'OFF' mode before adjusting settings,
