FAN COIL TYPE - This step instructs the thermostat
how to set the G, G2, and G3 outputs to yield the
desired fan speeds. Since this a low voltage
thermostat, the fan coil should have multiple relays or
contactors to supply the voltages needed for the fan
motor. Most fan coils will have 3 relays and require
only one relay to be driven at a time. However,
many models of Carrier or IEC fan coils contain a
relay board with special logic that requires different
output settings from the thermostat. If there is any
question, please contact the fan coil manufacturer.
