Programmable - Change setpoints

Pressing the Change setpoints keys allows the user to change any of the setpoints in the following

table. However, these setpoints should never be changed unless directed to do so by Product

Technical Support. Access level required is SERVICE.

Description

LCHLT Setpoint Ramp Rate

Adjustable 0.1°F/S to 2.0°F/S, Default: 0.1°F/S. When the chiller starts, the LCHLT

Setpoint is ramped from the LCHLT to the Active LCHLT Setpoint at the Ramp Rate to

prevent control windup and overshoot.

LCHLT Setpoint Start Offset

Adjustable 0.0 to 10°F, Default 5.0°F. When the chiller is off, the Active LCHLT Setpoint

is calculated as the LCHLT - LCHLT Setpoint Start Offset. This is the starting setpoint

that the Capacity Control will ramp from to the desired setpoint.

Discharge Superheat Limit Offset

Adjustable -5.0°F (diff) to 5.0°F (diff), Default: 0.0°F (diff).

Carryover Current Limit Offset

Adjustable -10.0% to +10.0%, Default 0.0°%

Capacity Control Gain

Adjustable Low, Medium, High, Default: Medium
