Control according to outdoor conditions
with room influence
The difference between the room temperature and
the setpoint value is measured and taken into
account for temperature control. This enables
taking into account possible heat inputs and
ensures a more accurate room temperature control.
Thus the differences with the room temperature
are taken into account and the room temperature
becomes more stable. The influence of the
difference is defined as a percentage.
The better the installation in the reference room
(accurate room temperature, correct installation
location, etc.) the higher will be the value that can
be set.
Example:
Approx 60%: the reference room is appropriate
-
Approx 20%: the reference room is inappropriate
-
Activation of the function requires taking into
account the following requirements:
A room sensor must imperatively be connected.
-
The "room influence" parameter must be set
-
between 1 and 99.
The reference room (where the room sensor is
-
installed) must not contain adjusted thermostatic
valves. Any thermostatic valves present in the
rooms must be fully open.
Control according to room temperature only
The flow temperature is adjusted according to the
room temperature setpoint, the current room
temperature and its evolution. A slight increase in
room temperature, for example, causes an
immediate drop in the flow temperature.
Activation of the function requires taking into
account the following requirements:
A room sensor must imperatively be connected.
-
The "room influence" parameter must be set to
-
100%.
The reference room (where the room sensor is
-
installed) must not contain adjusted thermostatic
valves. Any thermostatic valves present in the
rooms must be fully open.
Room Temperature Limitation
LINE
FUNCTION
932
Room temp limitation
The "room temperature limitation" function enables
shutting off the cooling circuit pump if the room
temperature falls below the adjusted room
temperature setpoint (with summer compensation
line 920) by more than the adjusted differential.
The cooling circuit pump is reinitiated as soon as
the room temperature rises again above the current
room temperature setpoint.
If the room temperature limitation function is
active, no cooling demand will be transmitted to
production.
The function is deactivated if:
no room temperature sensor is available
-
"Room influence limit." = ---
-
"Room influence" (line 928) = --- (simple control
-
according to outdoor conditions)
