The simplified connection diagram at left shows the
factory configured wiring set for 240V operation. If you
are going to use 208V exclusively, switch the two (2)
black wires on the 240V post of the primary side of the
transformer to the 208V post. This will ensure correct
secondary (low) voltages for the unit. This is only required
on remote thermostat units.
Remote Thermostat 208V Operation
Remote Thermostat Unit Operation
These units are controlled by the use of a remote
thermostat that will cycle the unit to maintain desired
room temperature. See thermostat operating instruction
sheet for details.
The fan speed switch controls high and low speed
fan operation. It is located on the control panel and is
independent of the thermostat.
Room Thermostats
Room thermostats are available from several different
manufacturers in a wide variety of styles. They range
from the very simple Bimetallic type to the complex
electronic set-back type. In all cases, no matter how
simple or complex, they are simply a switch (or series of
switches) designed to turn equipment (or components)
"ON" or "OFF" at the desired conditions.
An improperly operating, or poorly located room
thermostat can be the source of perceived equipment
problems. A careful check of the thermostat and wiring
must be made then to insure that it is not the source of
problems.
Location
The thermostat should not be mounted where it may be
affected by drafts, discharge air from registers (hot or
cold), or heat radiated from the sun or appliances.
The thermostat should be located about 5 Ft. above
If the supply voltage is 208V, the low voltage
transformer
MUST
be wired for 208V operation.
Failure to do so will result in lower control
voltages to the unit and can damage low voltage
components.
the floor in an area of average temperature, with good air
circulation. Close proximity to the return air grille is the
best choice.
Mercury bulb type thermostats MUST be level to control
temperature accurately to the desired set-point. Electronic
digital type thermostats SHOULD be level for aesthetics.
