Temperature Ramp
The user can define a temperature ramp to
adjust the set point automatically over a given
period of time.
A ramp is composed of 10 steps. Each step
specifies a day number and a temperature set
point for that day (the day number refers to
the animal age). Once the ramp is activated,
the controller changes the set point every
hour in a linear fashion between consecutive
steps of the ramp. When the last step is
reached, the controller keeps using the tem-
perature set point associated to that day.

Notes: Certain restrictions apply to reduce
the risk of errors:
1. The highest possible day number is 255.
2. Decreasing day numbers are not allowed.
3. Increasing temperatures are not al-
lowed.
4. The temperature variation cannot exceed
1,5°C (2,7°F) per day.
5. All ten steps must be specified. If you
don't need ten different steps, repeat the last
temperature for each unnecessary step.

I. Specifying Ramp Steps
Ramp steps can only be modified while the
ramp is disabled (see "IV. Deactivating the
Temperature Ramp" on page 14 to disable the
ramp).
• Select the SET POINT/TEMP RAMP menu.
The current temperature set point flashes on
the display – the value does not flash if the
ramp is enabled.
Repeat the following steps for each ramp
step (steps 0-9).
• Press the Other Functions button. The
day number of the first ramp step (step 0)
is displayed "d0 x" ("x" is the day number).
• Use the adjustment buttons to set the day
number of the first ramp step.
• Press the Other Functions button once
again. The temperature set point associated
with the first step of the ramp (step 0) is
displayed alternating with "t0". Adjust the
set point with the adjustment buttons.
• Press the Other Functions button again to
select the following ramp step.
• Proceed in similar fashion to set all ramp
steps and then, enable the ramp as explained
below.
