Model Number Notes
1.
Some field set up required.
2. Requires ReliaTel Options Module.
3. Requires Economizer.
4. All 22
nd
digit model numbers for
reheat coil (B) require additional
factory installed options: Frostat,
and 2” pleated filters.
5. Must be ordered with Through-
the-Base Electrical option or
Horizontal-Side Access and either
Unit Mounted Disconnect or
Circuit Breaker.
6. Available factory installed on
downflow AND horizontal units.
Verify with ordering system.
7.
Cannot be fused.
8. Must be factory installed when
using Through-the-Base Options.
9. ReliaTel Options Module is
required when ordering the
following accessories: Clogged
Filter Switch, Fan Fail Switch,
Condensate Overflow Switch,
Discharge Air Sensing Kit, Frostat,
Ventilation Override, Smoke
Detector, Dehumidification and
Modulating Gas Heat Furnace.
10. Option cannot be ordered in
conjunction with field installed
economizer on downflow units.
Must be factory installed. The
return air smoke detector may not
fit up or work properly on the
Voyager units when used in
conjunction with 3
rd
party
accessories (such as bolt on heat
wheels, economizers, and power
exhaust). Do not order the return
air smoke detectors when using
this type of accessory.
11. Unit mounted disconnect and
circuit breakers are mutually
exclusive of each other.
12. Through-the-base electrical
option or Horizontal-Side Access
must be ordered with either unit
mounted disconnect or circuit
breaker. When adding heat, you
must order Electric Heat.
13. This option consists of the Novar
return air sensor (Novar #WTS-10)
that is wired and shipped in the
return air section of the unit. The
sensor ships with approximately
15’ of extra wire for dropping
down the return air duct
(downflow only).
14. Available on high efficiency,
downflow units only.
15. All Factory Installed Options are
Built-to-Order. Check order
services for estimated production
cycle.
16. The Novar control option includes
the following factory installed and
wired devices: Novar ETM-2024 or

Option cannot be ordered in
conjunction with a factory
installed smoke detector.
17. For use with multi-speed and
SZVAV units only.
18. Novar is not available with SZ VAV
products.
19. Demand Control Ventilation
Option includes wiring only. The
C0
2
sensor is a field-installed only
option.
20. Frostat is standard on VAV units.
21. Supply and/or return smoke
detector may not be used with the
plenum smoke detector.
22. Only available where MOP is
above 60A.
23. 575 VAC option is 25kA.
24. Standard filters are not available
with Low Leak Economizers.
25. Human Interface is standard with
FDD (Fault Detection Diagnostics).
