Cooling Setpoints:
defines the target temperature
at which the cooling output
ends the cooling cycle.

differential between stages -
the interstage differential
between is this total differential
divided by the number of
stages. See example below.

minutes) between successive

Reclaim Setpoints: This section
defines when and how heating will

Delay
is the
total differential between heating
stages - the differential between
successive stages of heat is the total

Dehum. Setpoints:
defines the target humidity at
which the

Auxiliary Setpoints: Setpoint
Differential
Delay
defines the temperature at which
auxiliary heat may be used.
is the temperature
between the first stage of auxiliary
heat and the second stage of
auxiliary heat.
is the
minimum time (in minutes) between
successive auxiliary heat stages.
Lockouts: This area defines
the outside air temperature at
which the auxiliary heat,
cooling, and dehumidification
are locked out (the outputs are
not allowed to energize). If the
box has
a check mark, the heat reclaim
will operate while
dehumidification is on.

Alarm Setpoints: This
defines the high and low
temperatures and time
delays at which the
temperature alarms for this
zone are activated.
