Installation Instructions

SAFETY CONSIDERATIONS

Only trained, qualified personnel and service mechanics

should modify and install any electrical accessories on pack-

aged terminal air conditioners or heat pumps.

PACKAGE CONTENTS

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 the 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).

INSTALLATION

NOTE: This kit can only be installed on Wall Thermostat

models (RC or RP units).

Prepare Unit

1. Check to be sure unit is off and power to unit is

disconnected.

2. Remove front panel from the unit by grasping the panel

firmly near the bottom of both sides, then pulling panel

forward and upward to release magnetic latches and parti-

tion hooks.

Install Second Fan Speed Control Relay

1. Remove Terminal Access Cover and save. See Fig. 2.

2. Open control box by removing the 2 control box cover

screws shown in Fig. 2 and 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 3/8in. screws included.

Wire in Second Fan Speed Control Relay

1. Remove 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 cover.

2. Attach gray wire from relay assembly to terminal J2 next

to relay K3 on the PCB. See Fig. 4.

3. Remove the black fan wire from Fan Speed Selector

Switch (Rotary or Rocker) and re-attach to terminal 4 on

the relay assembly. See Fig. 4 and 5.

4. Remove the red fan wire from Fan Speed Selector Switch

(Rotary or Rocker) and re-attach to terminal 6 on the re-

lay assembly. See Fig. 4 and 5.

5. Remove Fan Speed Selector Switch.

For Wall Thermostat Units that have fan speed control

from a rotary fan speed selector switch on top of the con-

trol box cover:

• Remove the knob and rotary fan speed selector

switch from the control box cover by removing the

2 screws located under the knob shown in Fig. 2

and discard.

For Wall Thermostat Units that have fan speed control

from 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 L1 on relay K1.

7. Attach black wire from terminal 2 of relay assembly

(with goal post terminal) to L1 on relay K1.

8. Re-attach black wire (removed in step 6 above) to open

goal post terminal of L1 on relay K1. see Fig. 4 and 5.

9. Attach green ground wire from terminal 1 of the relay as-

sembly (with piggy back male terminal) to green ground

wire attached to the PE terminal on corner of PCB.

Attach both wires back on to the PE terminal on corner of

PCB. See Fig 7.

10. The blue wire connected to terminal 3 on the relay assem-

bly is the second fan speed signal wire, for connection to

the thermostat. The blue wire has a quick connect/discon-

nect terminal for easy disconnect and removal of the unit.

Route the blue wire out of the control box opening where

the terminal access cover was removed. See Fig. 8.

11. Dress wires using wire ties provided.

12. Close the control box door and secure by re-attaching

screws saved earlier (take care not to pinch any of the

wires when the control box cover is closed).

Connect Wall Thermostat

1. Mount wall thermostat to wall (install per mounting in-

structions included with the thermostat).

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 terminal block removed in pre-

vious step. See Fig. 10 and 11.

NOTE: Connect G2 to Blue Wire for second fan speed with the

crimp-type wire joint included with the kit.

4. Re-install the fully wired Wall Thermostat Terminal

Block to the PTAC unit through the terminal access open-

ing. See Fig. 9.

5. Re-install terminal access cover. See Fig. 2.

6. Re-install front panel.

7. If a rotary speed selector switch was removed in Step 5

above, there will be a hole in the control section of the

front panel (where HI/LOW fan speed was selected).

Cover the hole by replacing the existing Control Panel

label with the Blank Out Control Label included. See

Fig. 12.

8. Restore power to the unit.

IMPORTANT: Wall thermostat must be configured

for the correct equipment type for proper operation.

Program Heat Pump units with equipment type 11 and

Heat/Cool units with equipment type 13. Refer to next

section, Required Setup of Thermostat.

Required Setup of Thermostat

1. Enter Advanced Configuration mode. See Fig. 13.

2. The only configuration item that must be changed is the

type of equipment. For a heat pump unit, the type of

equipment must be changed to 11. For a Heat/Cool unit,

the type of equipment must be changed to 13.

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 thermostat has been fully installed and configured,

test all operating modes and fan speed control.

IMPORTANT: Failure to configure the Wall Thermostat

with the correct type of equipment will result in improper

operation of the thermostat and possibly, damage to the

PTAC unit.
