Set Point 1 — When Set Point Select (Setpoint Select, SP.SE) is configured to 1 (Setpoint 1), the unit’s active set point is based on Cooling Set Point 1 (Cooling Setpoint 1, CSP.1).

To configure this option with the Touch Pilot display:

DISPLAY NAME	PATH	LINE	VALUE
		NO.
Setpoint Select	Status→ GENUNIT	25	1 (Set Point 1)

To change this value, a Control Point Force must be applied. When configured correctly, Setpoint Control will indicate Setp 1.

To configure this option with the Navigator™ display:

ITEM	ITEM EXPANSION	PATH	VALUE
SP.SE	Setpoint Select	Operating Modes→ SLCT	Setpoint 1

Set Point 2 — When Set Point Select (Setpoint Select, SP.SE) is configured to 2 (Setpoint 2), the unit’s active set point is based on Cooling Set Point 2 (Cooling Setpoint 2, CSP.2).

To configure this option with the Touch Pilot™ display:

DISPLAY NAME	PATH	LINE	VALUE
		NO.
Setpoint Select	Status→ GENUNIT	25	2 (Set Point 2)

To change this value, a Control Point Force must be applied. When configured correctly, Setpoint Control (Status→ GENUNIT) will indicate Setp 2.

To configure this option with the Navigator display:

ITEM	ITEM EXPANSION	PATH	VALUE
SP.SE	Setpoint Select	Operating Modes→ SLCT	Setpoint 2

4 to 20 mA Input — When Set Point Select (Setpoint Select, SP.SE) is configured to 3 (4-20 mA Setp), the unit’s active set point is based on an field supplied, external 4 to 20 mA signal input to the Energy Management Module (EMM). Care should be taken when interfacing with other manufacturer’s control systems, due to power supply differences of full wave bridge versus half wave rectification. The two different power sup- plies cannot be mixed. ComfortLink™ controls use half wave rectification. A signal isolation device should be utilized if a full wave bridge signal generating device is used.

The following equation is used to control the set point. See Fig. 18.

Fahrenheit Set Point = 10 + 70(mA – 4)/16 (deg F) Celsius Set Point = –12.2 + 38.9(mA – 4)/16 (deg C)

To configure this option while using a Touch Pilot display:

DISPLAY NAME	PATH	LINE	VALUE
		NO.
Setpoint Select	Status→ GENUNIT	25	3 (4-20 mA Input)

To change this value, a Control Point Force must be applied. When configured correctly, Setpoint Control will indicate 4-20 mA.
