temperature is below
threshold.
7 Pipe Sensor
Threshold for
Heating
75 to
90
Range is 75°F to 90°F. Default is 80°F. Changes to Heat when pipe
sensor temperature is
above threshold.
8 Temperature Scale 0 Degrees Fahrenheit (°F); Default.
1 Degrees Celsius (°C).

to change between heating
and cooling and controls to
a single setpoint (Only
displayed for system types
5 or 7)
2 Heat and Cool Setpoints (2 setpoint method) Uses a deadband of no

setpoint - switching differential. Cool switching point
= setpoint + switching differential.
Available when Single
Setpoint is chosen for the
control method for 4-pipe
Auto (ISU 10)
