ACCESSORIES - FIELD INSTALLED
Thermostats
The unit-mounted thermostat in Figure 9.1 is provided as a field
installed kit for a model HER series only. Temperature range of
the dial setting is from 40°F to 90°F.
Other thermostats offered (not unit-mounted) are:
• Line-voltagesinglestage
• Line-voltage,2-stage(availableonPTEandVEmodels300,
400 and 500)
• Low-voltagesinglestage(requiresLow-VoltageControlkit.)

Pipe Suspension Adapter Kit
To facilitate threaded-pipe suspension mounting, a pipe-adapter
kit is available that includes two drilled pipe caps and two
3/8 - 16 x 1 1/2" capscrews. One kit is required to pipe-mount
HER series and two kits must be ordered to mount VE series unit
heaters. (On models VE50 through VE250 supplied with 480 volt,
3 phase service, clearance is not adequate for utilization of this
kit.) This kit cannot be used with Power-Throw
TM
(PTE series) unit
heaters.
Wall Mounting Bracket
For easier unit installation, where ceiling suspension is not
feasible, a wall-mounting bracket is available for models HER50
through HER250 and PTE300 through PTE500. The one-point
suspension illustrated in Figure 9.4 permits swiveling the unit
90° horizontally for most effective air flow direction. Fasteners for
mounting to wall are not furnished.
Low-Voltage Control
This control permits use of a low-voltage thermostat control
of electric unit heaters. High capacity models VE300, VE400,
VE500 and all PTE series heaters cannot operate in two stages
with a low-voltage thermostat; however, they will respond in
one stage with full operation of all elements. On model HER
series, this control cannot be combined with the unit-mounted
thermostat.
Summer-Winter Switch
In the winter position, the thermostat will cycle the fan and
heating elements. In the summer position, the switch will permit
the fan to run continuously while the heating elements are
controlled by the thermostat. Maximum switch rating is 10A
at 250 volts. Kit includes switch, conduit box, wire nuts, and
installation instructions.
