15. Parameter “6110: Time constant building” (default 20 h, range: 0 to 50 h), when the
external temperature varies, the room temperature changes in relation to the thermal
storage capacity of the building. This function is used to correct the response of the
delivery setpoint to changes in the external temperature.
Example:
• > 20: the room temperature responds more slowly to changes in the
external temperature.
• 10 ÷ 20: This setting can be used for the majority of buildings.
• < 10 the room temperature responds more quickly to changes in the
external temperature.
16. Parameters “790, 1090 and 1390: Optimum start control max”; passage from one
temperature level to another (reduced to comfort) is optimised so that the Comfort
setpoint can be reached in the respective “Activation switching time” (Xein). The
switching time in question can be set with parameters:
• 790 for circuit C1.
• 1090 for circuit C2.
• 1390 for circuit CP.
“Optimum start control” is possible with or without room units.
