7.2. 0-10V Heater
7.1. Heating Stages
The controller can control two independent
heating stages. These stages are independent
from one another and each operate according
to their own temperature settings and probe
selection.
The stop temperature of an heating stage
must be at least 0.5°F (0.3°C) higher than its
start temperature. The start (On) temperature
can be set from 0.5°F (0.3°F) below the set
point to -40°F (-40°C).

Operating Diagram
of a Heating Output
The controller has two 0-10V outputs that
can either be used to control heaters or fans.
To operate these outputs, the controller refers to the average temperature reading of
their assigned temperature probes (see sec.
4.7.3). This section explains how a 0-10V
heater work.

The 0-10V heater start at their minimum intensity when the temperature falls below the start
temperature of the output. The intensity of the
heater increases as the temperature decreases;
the maximum intensity is reached when the
temperature falls below the Max. Temperature
parameter setting.
Minimum & max speeds — Set the minimum
and maximum speeds of the 0-10V output.
The maximum speed must be greater than
the minimum speed.
Maximum output at — Set the temperature
at which the output reaches its maximum
speed (this parameter must smaller than the
start temperature).
Stop at — This is the temperature below
which the 0-10V output stops.
