4.15 Type of building construction
Enables the control system's rate of response to be matched to the type of building
construction.
1.
Press the line selection buttons to select line 74.
2.
Press the + / – buttons to select the type of building construction.
Setting range
Heavy, light
When the outside temperature varies, the room temperature changes at different rates,
depending on the building's thermal storage capacity.
The above setting ensures that the generation of the composite outside temperature
will be matched to the type of building construction. Also refer to " Composite outside
temperature".
Entry:
Heavy building structures:
The room temperature will respond slower to outside temperature
variations
Light
Light building structures:
The room temperature will respond quicker to outside temperature
variations
• Heavy building structures:
Buildings with thick walls or with external insulation
• Light building structures:
Buildings with a light envelope
4.16 Room influence
Owing to the temperature checkback signal received from the room, a constant room
temperature is maintained and, if required, boost heating or quick setback enabled.
The parameter defines the room influence on the control of the heating circuits.
Room temperature deviation is the temperature differential between actual room
temperature and room temperature setpoint.
1.
Press the line selection buttons to select line 75.
2.
Press the + / – buttons to select the room influence.
Setting range
None, on HC1, on HC2,
on HC1 + HC2
The setting will activate the room influence on the required heating circuits.
None
Room influence inactive: The measured room temperature will not
affect temperature control
