• UPM BOARD DEFAULT SETTINGS—Your UPM
board will come from the factory with the
following default settings:
• Freeze—”Terminals not jumped” on all the time
• Temp—30°F
• Lockout—2
• Reset—“Y”
• Alarm—“Pulse”
• Test—“NO”
• Hot/Dry Alarm— “Normally Open (NO)”
Considerations
1. Always check incoming line voltage power supply
and secondary control voltage for adequacy.
Transformer primaries are dual tapped for 208
and 230 volts. Connect the appropriate tap to
ensure a minimum of 18 volts secondary control
voltage. 24 volts is ideal for best operation.
2. Long length thermostat and control wiring leads
may create voltage drop. Increase wire gauge or
up-size transformers may be required to insure
minimum secondary voltage supply.
3. FHP recommends the following guidelines for wiring
between a thermostat and the unit: 18 GA up to 60
foot, 16 GA up to 100 ft and 14 GA up to 140 ft.
4. Do not apply additional controlled devices to
the control circuit power supply without
consulting the factory. Doing so may void
equipment warranties.
5. Check with all code authorities on
requirements involving condensate disposal/
over ow protection criteria.
ELECTRIC HEATER PACKAGE OPTION
Caution
The HP series heater package requires its own
electrical service separate from the heat pump’s
power supply. DO NOT attempt to wire the
package into the same circuit as the heat pump.
Factory installed internal electric heater packages
are available for CE series units. Two power supplies
are required when heater packages are utilized. The
power supply for the heater package (located in the
electric heater package control box) provides power
for the heater elements, the blower motor and the
control circuit for the unit. The power supply for the
unit provides power for the compressor. This allows
the electric heaters to continue to operate along with
the blower motor in the case of unit compressor and/
or compressor power supply failure. Each CE Series
model has a number of heater sizes available. Refer
to Figure #9 for heater package compatibility with
specic CE Series units, models nomenclature and
electrical data.
