ZONED HEATERS

To configure your system for zoned heaters, set dipswitch # 8 to ON.  Since
the two heater outputs function independently, different probes are assigned
to each output:  Probes 1 and 2 are assigned to Heater 1 and Probes 3 and
4 are assigned to Heater 2.  Individual probes can be turned on or off using
the dipswitch settings.  If both probes are activated for a given heater, the
average temperature from both probes is used.  To use stages 3 and 4 for
heating, set internal switches # 6 and 7 to ON.  To use only stage 4 for
heating, set internal switch # 6 to ON and # 7 to OFF.

Both heating zones can have negative and positive heater offsets.  A nega-
tive offset is used when controlling heat mats, for example.

To avoid ventilation problems when using zoned heating, a special protec-
tion is built into the device.  Suppose the animals are young and confined to
one part of the building (zone 1) while the rest of the building is heated at a
minimum level (zone 2). If the temperature difference between zones is too

great and zone 1 fans operate according to the average temperature for both
zones, cooling in zone 1 may be insufficient.  A built-in protection will oper-
ate the fans according to the probes of the zone with the highest tempera-
ture whenever the temperature difference between zones is greater than a
user-defined value.
