UNIT FEATURES
•
Unit Configuration
– There are many different configuration possibilities, through both dip
switches and the digital keypad, that allow you to configure the unit for your exact application.
See section on unit configuration for more details. The following are the configuration selections
that have not previously been mentioned:
•
Fahrenheit °F or Celsius °C
– The unit can display in either °F or °C.
•
Indoor Temperature Sensor Biasing
– Optimize the room temperature sensor reading
to your exact application (one for cooling and another for heating).
•
Display Setpoint or Room Temperature
– The unit can be configured to display the
room temperature OR setpoint only, during heating and cooling modes. See section on
unit configuration for more details.
•
Emergency Heat (for Heat Pump Only)
– In the event the compressor becomes non-opera-
tional, it can be disabled during heating mode allowing heating with the electric heater only.
•
Limit the Setpoint Range
– The unit can be configured to limit the controlling setpoint
range. The display will always show the complete setpoint range, but the controlling
setpoint will be limited to the configured minimum and maximum setpoints selected.
See section on unit configuration for more details.
•
Energy Management
– Sometimes known as Front Desk Control, an input is provided so
that the unit can be manually disabled from a different location. If the unit detects 24vac
on this input, it will automatically turn itself off. If no voltage is detected on the input, the
unit will run normally.
•
Wall Thermostat Control
– A wired wall thermostat can be connected to the unit. If it is,
the unit must be configured to disable the keypad. See section on wired inputs and unit
configuration for more details.
•
Automatic Quick Warm-up (for heat pump models only)
– If the room temperature falls to
5°F (2.8°C) below the set point temperature, the reverse cycle heat is shut off and the electric
strip heat is turned on for one cycle, until heating is satisfied. Then it reverts back to heat pump.
• Automatic defrost protection (for heat pump models only)
– When the outdoor temperature
gets too cold and the unit can no longer effectively heat with the compressor, the unit will
automatically switch to electric heating. The unit will then heat with electric heat until the out-
side temperature rises enough to defrost the outdoor coil, so the compressor can be used again.
• Automatic room freeze protection
– When the room is unoccupied for long periods during the
colder months, the unit will automatically keep the room between 40°F (4.4°C) and 50°F (10°C).
Room freeze protection can be disabled by unit configuration dip switches. See System
Configuration section for more information.
