Description of Operation cont.
Emergency Heat
Emergency heat mode may be engaged by selecting at
the MasterStat. All zone thermostat fault LED's begin to
flash two quick flashes, followed by a pause, indicating
that emergency heat mode has been activated. The
temperature of the structure will be controlled by the
zone 1 MasterStat while other zones are ignored. When
a demand for heat occurs at the MasterStat all zone
dampers are opened and emergency heat is energized.
Emergency heat will continue to operate until the
MasterStat demand is satisfied.
Emergency heat mode may be exited by selecting OFF (or
one of the other mode selections) at the MasterStat, as well
as all zone thermostat fault LED's stop flashing, indicating
emergency heat mode has been deactivated and normal
IntelliZone2 operation may resume.
Continuous Blower
All dampers are open and the unit's blower will be operated
while heating or cooling is suspended for any zone(s)
selected for continuous blower operation at the zone
thermostat. Upon any heating or cooling call to the unit, all
continuous blower operation ceases.
Lockout Mode
(Single/Dual Speed Compressor)
During the unit lockout mode, the appropriate Fault code
will be communicated to the MasterStat and the blower
will operate continuously. If the collective zones translate
into a > 24% heating call, emergency heat operation will
occur and all zone dampers will open. Blower speed will be
highest selected speed setting at the heat pump.
