Tracer Summit Communications Link to factory-installed, tested communication board, via single twisted- pair wiring, addsTracer Summit communications to the system.

LonTalk LCI-C Interface LonTalk (LCI-C) communications capabilities are available, with communication link via single twisted-pair wiring to factory-installed, tested communication board.

External ChilledWater Setpoint External ChilledWater Setpoint is communicated to a factory-installed, tested communication board through a 2- 10Vdc or 4-20mA signal.

External Current Limiting External Current Limit Setpoint is communicated to a factory-installed, tested communication board through a 2- 10Vdc or 4-20mA signal.

External Base Loading

External Base Loading is communicated to a factory-installed and tested communication board through a 2-10Vdc or 4-20mA signal.

Ice Making Control

Controls and safeties allow operation with brine temperatures down to 20°F (-6.7°C) , and dual setpoints enable both ice making and daytime comfort cooling.

Programmable Relays

Default-set, factory-installed, programmable relays allow the operator to select four relay outputs from a list of eight. Available relays are: Alarm- Latching, Alarm-Auto Reset, General Alarm,Warning, Chiller Limit Mode, Compressor Running, Head Pressure Relief Request, andTracer Control.

ChilledWater Reset – Outdoor Air Temperature

Controls, sensors, and safeties allow reset of chilled water temperature, based on temperature signal, during periods of low outdoor air temperature (chilled water reset based on return chilled water temperature is standard).

Condenser-RegulatingValve Control

Chiller applies a Proportional Integrative Control (PID) algorithm to control water regulating valve via 0-10Vdc signal.

Percent of Full Run LoadAmps Output Control system indicates the active chiller percent of full run load amps, based on a 0-10Vdc signal.

Condenser Pressure Output Control system indicates chiller differential pressure or condenser pressure, based on a 0-10Vdc signal.

Refrigerant Monitor Input

Control system indicates refrigerant monitor status of 0-100 or 0-1000 ppm (user selectable), based on a 2-10Vdc / 4-20 mA signal.
