6 2 2
Slope of Outdoor Reset Curve
0.2 -0.8 0.6 (low temperature)
0.4 - 3.5 1.3 (high temperature)
See graph and description of Parameter 422.
6 2 3
Parallel Shift of Reset Curve
-12 - +12 (when 4.2.0 = 0)
0
-25 - +25 (when 4.2.0 = 1)
See description of Parameter 423.
6 2 4
Room Sensor Inuence 0 - 20
2 if Parameter 4.2.0 = 0
4 if Parameter 4.2.0 = 1
Adjusts the inuence of room temperature on target boiler temperature - a higher setting causes a greater increase to the boiler
target temperature as the indoor temperature drops below room setpoint. Only applicable when using an optional NTI Room
Sensor and when 6.2.1 = 2 or 4.
6 2 5
MAXIMUM temperature setting
86 - 179 °F 179 if Parameter 6.2.0 = 1
68 - 122 °F 120 if Parameter 6.2.0 = 0
6.2.5 sets the allowable boiler operating temperature range for Zone 3 heating, limiting Automatic Temperature Control and
manual adjustments from the User Menu.
6 2 6
MINIMUM temperature setting
86 - 179 °F 120 if Parameter 6.2.0 = 1
68 - 122 °F 80 if Parameter 6.2.0 = 0
6.2.6 sets the allowable boiler operating temperature range for Zone 3 heating, limiting Automatic Temperature Control and
manual adjustments from the User Menu.
