Installation Instruction

Winter Start Control

NOTE: Read the entire instruction manual before starting the

installation.

SAFETY CONSIDERATIONS

Installing and servicing air conditioning equipment can be

hazardous due to system pressures and electrical components. Only

trained personnel should install or service air conditioning

equipment.

Untrained personnel can perform basic maintenance functions such

as cleaning coils, or cleaning and replacing filters. All other

operations should be performed by trained service personnel.

When working on air conditioning equipment, observe precautions

in the literature, on tags, and on labels attached to the unit.

Recognize safety information. This is the safety--alert symbol

When you see this symbol on the unit and in instructions or

manuals, be alert to the potential for personal injury.

Understand these signal words; DANGER, WARNING, and

CAUTION. These words are used with the safety--alert symbol.

DANGER identifies the most serious hazards which will result in

severe personal injury or death. WARNING signifies hazards

which could result in personal injury o r death. CAUTION is used

to identify unsafe practices which may result in minor personal

injury or product and property damage. NOTE is used to highlight

suggestions which will result in enhanced installation, reliability, or

operation.

Follow all safety codes. Wear safety glasses and work gloves.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or

death.

Before beginning any installation or modification, be sure the

main electrical disconnect switch is in the OFF position. TAG

THE DISCONNECT SWITCH WITH A SUITABLE

WARNING LABEL.

This kit is for 24 VAC applications ONLY. Do No t use or

connect to any high voltage wiring.

WARNING

Use only the kit components described in this installation

procedure.

INTRODUCTION

This instruction covers the installation of winter start control Part

No. KAAWS0101AAA on split -- system air conditioners. The

device is designed to alleviate nuisance opening of the

low--pressure switch by bypassing it for the first 3 minutes of

operation.

DESCRIPTION AND USAGE

Winter start control must be used where low evaporator

temperatures, or nuisance tripping of low--pressure switch may be

encountered.

The kit contains the following items:

(1) Time--Delay Relay (TDR) CESO130062 --00

(1) Installation Instructions

(1) 13” (330 mm) Blue (tap) Wire

(1) 13” (330 mm)Yellow Wire

(1) 13” (330 mm) Brown Wire

(1) Insulated Tap Connector (HY89TC014)

INSTALLATION

NOTE: If a fully communicating Infinity/Evolution Control is

being used for low ambient cooling, a winter start control is not

required.

For outdoor units with Infinity/Evolution and TechAssist

single--stage control boards:

1. Mount the winter start control board in outdoor control box.

2. Connect the following wires to the TDR:

S 13” (330 mm) Yellow wire to T1 (24 VAC input)

S 13” (330 mm) Brown wire to T3 (24 VAC common)

S 13” (330 mm) Blue--tap wire to T2 (N.O. relay contact)

3. Secure the open end of Blue Tap wire to the insulated tap

connector (see Fig. 1). To do this, simply butt the tap-- wire

against the wire stop. Fold the top cover half over to meet

the base. Squeeze on the top cover and base with ordinary

pliers until the latch locks. DO NOT place pliers on top of

the raised plastic flange.

4. Identify the LPS (low pressure switch) connector at the

ODU circuit board, and identify the 24vac LPS run-- wire

(or main lead) for the pressure switch. The LPS run--wire is

different between circuit boards (see Fig. 3 and Fig. 4).

S Infinity/Evolution (HK38EA004) LPS run--wire is

connected to pin #1 (see Fig. 3).

S TechAssist (HK35AC005) LPS run--wire is connected to

pin #2 (middle pin) (see Fig. 4).

Secure the LPS run--wire by inserting the run--wire into the

remaining open section of connector. Fold the base over to

meet the run--wire section. Squeeze on the base and run--

wire section with ordinary pliers until the latch locks. DO

NOT place pliers on top of the raised plastic flange.

5. Connect the open strip end of 13” (330 mm) Brown wire to

connections.

6. Connect the open strip end of 13” (330 mm) Yellow wire to

(Y) 24vac side of the ODU and thermostat field connec-

tions.

NOTE: The Winter Start Control time--delay logic is now wired in

parallel with the outdoor unit low-- pressure switch. When indoor

thermostat calls, the TDR logic will energize (closing T1, T2) for

approximately 3--minutes bypassing the LPS. After 3-- minutes, the

TDR logic will de--energize (opening T1, T2) and the LPS circuit is

restored (see Fig. 2).

Troubleshooting Upon Startup

If the TDR does not energize, make sure LPS run and tap wires are

not reversed (double check figures below). You can also apply

24vac direct to T1 and T3 to verify that the TDR relay will

energize.
