4.8 Setpoint Ramp Set Up Group
Introduction
The Setpoint Ramp 1 and 2 Set Up groups contain the Function parameters that enable you to configure
two setpoints. Each setpoint (SP RAMP 1 and SP RAMP 2) can be configured only one of three ways:
ramp, rate, or setpoint program.
Single Setpoint Ramp
Setpoint will ramp between the current local setpoint and a final setpoint over a time interval of up to 255
minutes (SP RAMP).
Setpoint Rate
The Setpoint Ramp Set Up group also contains the function parameters that let you configure a specific rate
of change for any local setpoint change (SP RATE). It includes selections for Rate Up and Rate Down.
Setpoint Program
Also included under this group are prompts for configuring a 36-segment Setpoint program (SP PROG).
The prompts and instructions for Setpoint programming are presented in the
Section 6 Setpoint Ramp/Soak
Programming Option.
You can start and stop the ramp/program using the
RUN/HOLD
key.
Setpoint Ramp/ Program group prompts
Table 4-7 lists all the function prompts in the Setpoint Ramp 1 or 2 setup group and their definitions.
When you enable the ramp type (SP RAMP, SP RATE, SP PROG) the other two types are hidden from the
