ZONED HEATERS
To configure your system for zoned heaters, set dipswitch # 9 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 7 and 8 for heating, set internal
switches # 7 and 8 to ON. To use only stage 8 for heating, set
internal switch # 7 to ON and # 8 to OFF.
Both heating zones can have negative and positive heater offsets. A
negative offset is used when controlling heat mats, for example.
To avoid ventilation problems when using zoned heating, a special
protection 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 accord-
ing to the average temperature for both zones, cooling in zone 1 may
be insufficient. A built-in protection will operate the fans according to
the probes of the zone with the highest temperature whenever the
temperature difference between zones is greater than a user-defined
value..
