See description of Parameter 423.
6. 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 6.2.1 = 2 or 4.
6. 2. 5 Max Temperature 68 95 - 179 °F 179
6.2.5 sets the allowable boiler operating temperature
