if Parameter 4.2.0 = 1
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
HTP Room Sensor and when 6.2.1 = 2 or 4.
