5. Setpoint Rate/Ramp/Soak Program Operation

5.1 Setpoint Ramp Rate

Introduction
When you have configured a Setpoint Ramp Rate, it will apply immediately to any
local setpoint change.
Configuration Check
Make sure you:
• enable SP RATE
• disable SP RAMP and SP PROG
• set an upscale or downscale rate value
ATTENTION
A value of 0 will imply an immediate change in setpoint; that is, NO RATE applies. See
Section 3.4 for details.
Operation
When a local setpoint change is made, the controller will ramp from the original
setpoint to the new one at the rate specified. This changing (current) setpoint can be
viewed as SPn on the lower display.
Press the LOWER DISPLAY key until you see SPn and the setpoint value in the
lower display.

5.2 Single Setpoint Ramp

Introduction
When you have configured a single setpoint ramp, it will occur between the current
local setpoint and a final local setpoint over a time interval of from 1 to 255 minutes.
You can RUN or HOLD the ramp at any time.
Configuration Check
Make sure you:
• enable SP RAMP
• disable SP RATE and SP PROG
• set the ramp time in minutes
• set the final setpoint value
See Section 3.4 for details.
