Setting the Segment Type
The program ramp rate is designed to reduce the heatup rate or cooling rate that the
furnace normally exhibits. When not using this feature, the furnace will operate at its
maximum heating and cooling capability.
When the program ramp has ended or has been reset, the furnace will continue to
maintain setpoint temperature. It will not cool to ambient temperature unless the
setpoint is set to ambient temperature by the program or by the operator.
There are five segment types. Proceed with the following steps according to the type of segment you
have selected.
rmP.r (Ramp)
To ramp linearly at a set rate to a specified temperature:
1. Press the PAGE button until you reach the program list (ProG LiSt).
2. Press the SCROLL button until display reads,”tYPE.”
3. Press the UP or DOWN button until display reads, “rmP.r.”
Steps 4 and 5 are used in the 4 program model only. If you are using an 8 segment program, skip to
step 6.
4. Press the SCROLL button until display reads “Hb.”
5. Press the UP or DOWN button to toggle between “bAnd, Hi, Lo and OFF.”
6. Press the SCROLL button until display reads, “tGt.”
7. Press the UP or DOWN button to set a target setpoint.
8. Press the SCROLL button until display reads,”rAtE.”
9. Press the UP or DOWN button to select a value in ramp units (seconds, minutes or hours; set in
the “rmP.U” parameter).
rmP.t
To ramp to a specified temperature at a set time:
1. Press the PAGE button until you reach the program list (ProG LiSt).
2. Press the SCROLL button until display reads, “tYPE.”
3. Press the UP or DOWN button until display reads, “rmP.t.”
4. Press the SCROLL button until display reads, “tGt.”
5. Press the UP or DOWN button to set a target setpoint.
6. Press the SCROLL button until display reads, “dur.”
7. Press the UP or DOWN button to select a time in ramp units (seconds, minutes or hours; set in
the “rmP.U”parameter.
