Premier E Line Voltage 208-230/60/1 Control Box
ACCESSORY RELAY
A set of "dry" contacts has been provided to control accessory devices, such as water solenoid
valves on open loop installations, electronic air cleaners, humidifiers, etc. This relay contact should
be used only with 24 volt signals and not line voltage power. The relay has both normally open
and normally closed contacts and can operate with either the fan or the compressor. Use DIP switch
SW2-3 to cycle the relay with fan or compressor. The relay contacts are available on terminals #2 and
#3 of P3. (See the wiring schematic on pages 14-15 for details).
208 VOLT OPERATION
All Premier E units are factory wired for 230 volt operation. There is a switch located on the control
box, which allows the installer to select 208 volt unit operation. (Refer to Figure 13 on page 13 for
switch location).
UNIT POWER CONNECTION
Connect the incoming line voltage wires to L1
and L2 of the contactor as shown in Figure 13
below. Consult the Unit Electrical Data section on page 16 for correct fuse size.
EXTERNAL LOOP PUMP POWER CONNECTION
If the unit is to be used with an external loop pump (FC1 or FC2 flow center), the pump(s) will be
connected to the terminals on PB1 in the unit electrical box as shown in Figure 10 below. The pumps
will automatically be cycled as required by the unit or by a slave signal from another Premier E unit
sharing the flow center (see Figure 7 on page 7).
