ZONED HEATERS
To configure your system for zoned heaters, set dipswitches # 7 and 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.
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.

•
When
room temperature < Set Point
, stage 1 fans run at minimum
speed according to the minimum ventilation cycle.
•
At Set Point
: stage 1 fans stop operating according to the minimum
ventilation cycle and increase in speed as the room temperature rises.
•
At Set Point + bandwidth 1
: stage 1 fans reach full speed.
If room temperature rises:
The TC5-1N5FAB controls one stage of variable-speed fans (Stage 1), one
stage of constant-speed fans (Stage 2) and one optional stage of constant-
speed fans (Stage 3) as well as curtains for natural ventilation. If the floating
stage 3 is disabled (internal swich #10 Off), the curtains opererate after the
stage 3. If the floating stage 3 is enabled (internal switch # 10 On), the
curtains operate after the stage 2 as shown below:
