Room temperature setpoints
If, e.g., the thermostat receives a new Comfort basic setpoint from the bus (object
25 - Room temp: Comfort basic setpoint), the current Comfort setpoint is not
updated immediately. Only when the operating mode is set back to Comfort, the
Comfort setpoint is updated with the new Comfort basic setpoint.
This setback is only executed when the change of the operating mode is
commanded
Operating mode is commanded by
Pressing the mode button or via bus.
Pressing the mode button or via bus, not by window contact.
Pressing the mode button or via bus, not by presence detector and hotel
presence detector (digital input or bus).
When "Temporary comfort setpoint" is disabled via P103, the Comfort setpoint is
set back to the Comfort basic setpoint (stored in P011) immediately as soon as the
Comfort basic setpoint is changed.
For Comfort or energy saving purposes, the setpoint setting range can be limited
by selecting the most appropriate setpoint concept:
● Setpoint Comfort concept (P010 = 1) for maximum user comfort
● Setpoint energy saving concept (P010 = 2) to save energy
● The setpoint limit can be set via P013 (Comfort setpoint minimum) and P016
(Comfort setpoint maximum). Both heating and cooling setpoints are adjustable
between these two limits.
● The user adjusts the desired setpoint and the thermostat controls the room
temperature accordingly.
● For 4-pipe applications, the selected Comfort setpoint is in the middle of the
dead zone (P055). The unit stops to energize the heating/cooling outputs as
soon as the room temperature reaches the dead zone.
Cooling setpoint adjustable:
18…25 °C
Heating setpoint adjustable:
18…25 °C
● This allows users to limit the setpoint setting range for heating and cooling
independently.
● The setpoint limits for heating can be set via P013 (Comfort setpoint minimum)
and P014 (Comfort setpoint maximum heating). The setpoint limits for cooling
can be set via P015 (Comfort setpoint minimum cooling) and P016 (Comfort
setpoint minimum).
Cooling setpoint adjustable:
25…40 °C
Heating setpoint adjustable:
5…21 °C
● For 4-pipe applications:
– The thermostat runs on the setpoint of the active sequence:
In heating mode, the heating setpoint is active and adjustable via rotary
knob.
In cooling mode, the cooling setpoint is active and adjustable via rotary
knob
