4. 2. 3 Heating Curve Offset -25 - +25 0
When the Reset Curve results in a boiler target
temperature that is too high or too low (i.e., heats the
building too quickly or slowly), Parallel Shift can be used
to offset the curve up or down to increase or decrease the
boiler target temperature.
NOTE: Adjusting Parallel Shift is only possible when Auto
Boost is OFF (4.7.5 = 0).
4. 2. 4 Room Sensor Influence 0 - 20 4
Adjusts the influence 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 4.2.1 = 2 or 4.
4. 2. 5 Max Temperature 68 - 179 °F 179
4.2.5 sets the allowable boiler operating temperature
range for Zone 1 heating, limiting Automatic Temperature
Control and manual adjustments from the User Menu.
4. 2. 6 Min Temperature 68 - 1179 °F 95
4.2.6 sets the allowable boiler operating temperature
range for Zone 1 heating, limiting Automatic Temperature
