FIELD SELECTABLE INPUTS

Jumpers and DIP (dual in-line package) switches on the

control board are used to customize unit operation and can be

configured in the field.

Complete C Control Jumper Settings (Refer to
Fig. 13 and 16)

WATER COIL FREEZE PROTECTION (FP1) LIMIT

SETTING — Select jumper 3, (JW3-FP1 Low Temp) to

choose FP1 limit of 10 F or 30 F. To select 30 F as the limit,

DO NOT clip the jumper. To select 10 F as the limit, clip the

jumper.
AIR COIL FREEZE PROTECTION (FP2) LIMIT SET-

TING — Select jumper 2 (JW2-FP2 Low Temp) to choose

FP2 limit of 10 F or 30 F. To select 30 F as the limit, DO NOT

clip the jumper. To select 10 F as the limit, clip the jumper.
ALARM RELAY SETTING — Select jumper 1 (JW1-AL2

Dry) for connecting alarm relay terminal (AL2) to 24 vac (R)

or to remain as a dry contact (no connection). To connect AL2

to R, do not clip the jumper. To set as dry contact, clip the

jumper.

Complete C Control DIP Switches —

The Con-

plete C control has 1 DIP switch block with two switches.

Refer to Fig. 13 and 16.
PERFORMANCE MONITOR (PM) — DIP switch 1 will

enable or disable this feature. To enable the PM, set the switch

to ON. To disable the PM, set the switch to OFF.
STAGE 2 — DIP switch 2 will enable or disable compressor

delay. Set DIP switch to OFF for stage 2 in which the compres-

sor will have a 3-second delay before energizing.
NOTE: The alarm relay will not cycle during Test mode if

switch is set to OFF, stage 2.

Deluxe D Control Jumper Settings (Refer to
Fig. 14, 15, and 17)

WATER COIL FREEZE PROTECTION (FP1) LIMIT

SETTING — Select jumper 3, (JW3-FP1 Low Temp) to

choose FP1 limit of 10 F or 30 F. To select 30 F as the limit,

DO NOT clip the jumper. To select 10 F as the limit, clip the

jumper.
AIR COIL FREEZE PROTECTION (FP2) LIMIT SET-

TING — Select jumper 2 (JW2-FP2 Low Temp) to choose

FP2 limit of 10 F or 30 F. To select 30 F as the limit, DO NOT

clip the jumper. To select 10 F as the limit, clip the jumper.
ALARM RELAY SETTING — Select jumper 4 (JW4-AL2

Dry) for connecting alarm relay terminal (AL2) to 24 vac (R)

or to remain as a dry contact (no connection). To connect AL2

to R, do not clip the jumper. To set as dry contact, clip the

jumper.
LOW PRESSURE SETTING — The Deluxe D control can

be configured for Low Pressure Setting (LP). Select jumper 1

(JW1-LP Norm Open) for choosing between low pressure in-

put normally open or closed. To configure for normally closed

operation, do not clip the jumper. To configure for normally

open operation, clip the jumper.

Deluxe D Control DIP Switches —

The Deluxe D

control has 2 DIP switch blocks. Each DIP switch block has 8

switches and is labeled either S1 or S2 on the circuit board.

Refer to Fig. 14, 15, and 17.

DIP SWITCH BLOCK 1 (S1) — This set of switches offers

the following options for Deluxe D control configuration:
Performance Monitor (PM) — Set switch 1 to enable or dis-

able performance monitor. To enable the PM, set the switch to

ON. To disable the PM, set the switch to OFF.
Compressor Relay Staging Operation — Switch 2 will en-

able or disable compressor relay staging operation. The com-

pressor relay can be set to turn on with stage 1 or stage 2 call

from the thermostat. This setting is used with dual stage units

(units with 2 compressors and 2 Deluxe D controls) or in mas-

ter/slave applications. In master/slave applications, each com-

pressor and fan will stage according to its switch 2 setting. If

switch is set to stage 2, the compressor will have a 3-second de-

lay before energizing during stage 2 demand.
NOTE: If DIP switch is set for stage 2, the alarm relay will not

cycle during Test mode.
Heating/Cooling Thermostat Type — Switch 3 provides selec-

tion of thermostat type. Heat pump or heat/cool thermostats

can be selected. Select OFF for heat/cool thermostats. When in

heat/cool mode, Y1 is used for cooling stage 1, Y2 is used for

cooling stage 2, W1 is used for heating stage 1 and O/W2 is

used for heating stage 2. Select ON for heat pump applications.

In heat pump mode, Y1 used is for compressor stage 1, Y2 is

used for compressor stage 2, W1 is used for heating stage 3 or

emergency heat, and O/W2 is used for RV (heating or cooling)

depending upon switch 4 setting.
O/B Thermostat Type — Switch 4 provides selection for heat

pump O/B thermostats. O is cooling output. B is heating out-

put. Select ON for heat pumps with O output. Select OFF for

heat pumps with B output.
Dehumidification Fan Mode — Switch 5 provides selection

of normal or dehumidification fan mode. Select OFF for dehu-

midification mode. The fan speed relay will remain OFF dur-

ing cooling stage 2. Select ON for normal mode. The fan speed

relay will turn on during cooling stage 2 in normal mode.
Switch 6 — Not used.
Boilerless Operation — Switch 7 provides selection of boiler-

less operation and works in conjunction with switch 8. In

boilerless operation mode, only the compressor is used for

heating when FP1 is above the boilerless changeover tempera-

ture set by switch 8 below. Select ON for normal operation or

select OFF for boilerless operation.
Boilerless Changeover Temperature — Switch 8 on S1 pro-

vides selection of boilerless changeover temperature set point.

Select OFF for set point of 50 F or ON for set point of 40 F.

If switch 8 is set for 50 F, then the compressor will be used

for heating as long as the FP1 is above 50 F. The compressor

will not be used for heating when the FP1 is below 50 F and the

compressor will operates in emergency heat mode, staging on

EH1 and EH2 to provide heat. If a thermal switch is being used

instead of the FP1 thermistor, only the compressor will be used

for heating mode when the FP1 terminals are closed. If the FP1

terminals are open, the compressor is not used and the control

goes into emergency heat mode.
DIP SWITCH BLOCK 2 (S2) — This set of DIP switches is

used to configure accessory relay options. Refer to Fig. 14, 15,

and 17.
Switches 1 to 3 — These DIP switches provide selection

of Accessory 1 relay options. See Table 12 for DIP switch

combinations.
Switches 4 to 6 — These DIP switches provide selection

of Accessory 2 relay options. See Table 13 for DIP switch

combinations.

IMPORTANT: Jumpers and DIP switches should only

be clipped when power to control board has been turned

off.
