heat. This acts to prevent the unnecessary use of auxiliary heat. In
addition, when an outdoor sensor is attached, the system can be set
to lock out auxiliary heat for outdoor temperatures above an
installer selectable value. This will be covered under System
Configuration.
SYSTEM CONFIGURATION
Comfort Zone II -B must be configured to match the type of
equipment connected to it. In addition, there are several choices of
configuration based on how the user wants the system to operate.
Configuration is done in 2 parts. First is the setting of 8 DIP
switches on the Equipment Controller. The second is a group of
software selections made via User Interface. Follow the sequence
below for easy setup.
Configuration of the Equipment Controller is done first with the
power off. Then power is applied and the User Interface is
configured with power on.
NOTE: A DIP switch module is oriented with switch 1 at the
bottom and switch 8 at the top. Refer to Fig. 12 for switch
orientation and labels.
Step 1—Equipment Controller Configuration
Located near bottom of Equipment Controller circuit board, there
is an 8 section DIP switch. The use of each switch is described

below. Using a pen or pencil, set each switch to its proper state.
ON is to the left and is the factory setting. OFF is to the right. Fig.
12 is a pictorial drawing of this selector switch.
Switch 1—Selects AC or HP.
ON—Selects AC.
OFF—Selects HP.
Switch 2—Selects single- or 2-speed compressor.
ON—Selects single speed.
OFF—Selects 2 speed.
Switch 3—Selects 3-stage electric heat. Equipment must include
FK or FV series fan coil with single-speed heat pump and properly
selected 3-stage electric heater.
ON—Normal 1- or 2-stage electric heat.
OFF—Special 3-stage electric heat.
Switch 4—Selects Smart Recovery in both heating and cooling.
The system starts adjusting temperature 1-1/2-hours earlier than
selected recovery time so it will arrive at new temperature at
selected time.
ON—Smart recovery.
OFF—Normal recovery.
Switch 5—Zone system address selection. When 2 zoning systems
are connected together, the second system should be set to OFF.
