OUTDOOR TEMP FOR MIN TARGET
1
OUTDOOR TEMP FOR MIN TARGET means
the outdoor temperature at which the target
temperature reaches its minimum (Min Target
Temp)
2
In the examples of Figure 7, this occurs at 70°F
2
(the factory default)
OUTDOOR TEMP FOR MAX TARGET
1
OUTDOOR TEMP FOR MAX TARGET means
the outdoor temperature at which the target
temperature reaches its maximum value (Max
3
Target Temp)
2
In the examples of Figure 7, this occurs at 0°F
outdoor (the factory default setting)
3
OUTDOOR TEMP FOR MAX TARGET should
equal the Outdoor Temp (outdoor design
temperature) for the installation's location
4
Outdoor reset operation
1
Set desired temperatures for space heating

For an explanation of the target temperatures and
associated outdoor temperatures, see Figure 7

accessed in the priority menu for the applicable
system For detailed explanations of the priority
menus, see Figure 34, page 84
MAX TARGET TEMP
Set Max Target Temp to the required supply water
6
temperature for the system at design maximum heat
loss (typically 180°F for finned tube baseboard on
new installations)
MIN TARGET TEMP
1
Min Target Temp should equal the desire
minimum supply water temperature for the
7
system
2
The Min Temp is the setpoint whenever the ODT
temp is above the ODT For Min Target and below
the WWSD temps
NOTICE
8
Setting this value below the Outdoor Temp for Min
Target may reduce the performance of the heating
system at warmer outdoor temperatures.

This could be set as low as 60°F, which would
supply "zero heat" when outdoor temperature is
70°F, because supply water temperature would
close to room temperature See examples in
