Field Selectable Inputs

16.Air coil is clean.

17.Control field-selected settings are correct.

AIR COIL — To obtain maximum performance, clean the air coil before starting the unit. A 10% solution of dishwasher detergent and water is recommended for both sides of the coil. Rinse thoroughly with water.

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.

IMPORTANT: Jumpers and DIP switches should only be clipped when power to control board has been turned off.

Complete C Control Jumper Settings

WATER COIL FREEZE PROTECTION (FP1) LIMIT SETTING — Select jumper 3 (JW3-FP1 Low Temp) to choose FP1 limit of either 30 F or 10 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 either 30 F or 10 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) to either connect 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.

Deluxe D Control Jumper Settings

ALARM RELAY SETTING — Select jumper 4 (JW4-AL2 Dry) to either connect 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 input normally opened or closed. To configure for normally closed operation, DO NOT clip the jumper. To configure for normally open operation, clip the jumper.

Complete C Control DIP Switches — The Com- plete C control has 1 DIP (dual in-line package) switch bank with five switches labeled SW1. See Fig. 15, 17 , 19, and 21.

PERFORMANCE MONITOR (PM) — The PM is a unique feature that monitors water temperature and will display a warn- ing when heat pump is beyond typical operating range. Refer to Control Operation section for detailed information. 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.

SWITCH 3 — Not used.

DDC OUTPUT AT EH2 — Switch 4 provides a selection for Direct Digital Control (DDC) operation. If set to DDC output at EH2, the EH2 terminal will continuously output the last fault code of the controller. If the control is set to EH2 Normal, then EH2 will operate as standard electric heat output. Set the switch to ON to set the EH2 to normal. Set the switch to OFF to set the DDC output at EH2.

FACTORY SETTING — Switch 5 is set to ON. Do not change the switch to OFF unless instructed to do so by the factory.

Deluxe D Control DIP Switches — The Deluxe D control has 2 DIP (dual in-line package) switch banks. Each bank has 8 switches and is labeled either S1 or S2 on the cir- cuit board. See Fig. 16, 18, 20, 22, and 23.

DIP SWITCH BANK 1 (S1) — This set of switches offers the following options for Deluxe D control configuration:

Performance Monitor (PM) — The PM is a unique feature that monitors water temperature and will display a warning when heat pump is beyond typical operating range. Set switch 1 to enable or disable 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 delay 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 se- lection 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 thermostats. 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 reversing valve (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 thermostats with O output. Select OFF for thermostats with B output.

Dehumidification Fan Mode — Switch 5 provides selection of normal or dehumidification fan mode. Select OFF for dehumidification mode. The fan speed relay will remain OFF during cooling stage 2. Select ON for normal mode. The fan speed relay will turn on during cooling stage 2 in normal mode.

Output — Switch 6 provides selection for DDC operation. If set to DDC output at EH2, the EH2 terminal will continuously output the last fault code of the controller. If the control is set to EH2 normal, then the EH2 will operate as standard electric heat output. Set the switch to ON to set the EH2 to normal. Set the switch to OFF to set the DDC output at EH2.

Boilerless Operation — Switch 7 provides selection of boil- erless 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.
