0-10V Heating Curve

The controller can automatically change the
temperature at which the 0-10V heater (or
heat mat) starts over time by using a curve.
This heating curve is optional. Refer to the User
Setup menu in section 4.4 to enable it.

The 0-10V heat curve is made of 10 steps.
Each step specifies a day number and a start
temperature of the 0-10V heating output for
that day. Once it is activated, the controller
changes this start temperature every hour in
a linear fashion between consecutive steps of
the curve. When the last step is reached, the
controller keeps using the start temperature
associated with that day.
Notes
Certain restrictions apply to reduce the
risk of errors:
1. The highest day number is 365.
2. Decreasing day numbers is not allowed.
3. Increasing heater set points is not allowed.
4. All ten steps must be specified. If you
don't need ten different steps, repeat the
last temperature for each unnecessary step.
Refer to section 4.2 on page 10
to set the current day number.

Curve status
Off
Day numbers — Set the day at which each
curve step starts.
Setp — Assign a temperature set point (start
temperature of the heating output) to each
step of the curve.
Curve status — Select "Yes" to enable the
curve (or "No" to disable it). Once the curve
is on, the controller automatically adjusts
the set point between consecutive points of
the curve; for this reason, curve steps can-
not be modified while the curve is running.
If all curves are disabled (Min.Vent,
Set Point & 0-10V Heat curves), the
controller will automatically set the day
number back to 1 day when a curve
is being activated.
