For comfort or energy saving purposes, the setpoint setting range can be limited by
selecting the most appropriated setpoint concept:
● Setpoint Comfort concept (P010 = 1) for the maximum comfort of the user
● Setpoint energy saving concept (P010 = 2) for energy saving purposes
● 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 the user 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 with 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
– Switching from the heating setpoint to the cooling setpoint and vice-versa
occurs when the room temperature reaches the adjusted limitation (P014 or
P015) of the inactive sequence. For example, the thermostat is in heating
sequence and operates using the heating setpoint. When the room
temperature reaches P015, the thermostat switches to cooling mode and
operates using the cooling setpoint, as long as the room temperature does
not drop below P014.
Use P019 and P020 to adjust the Economy mode setpoints.
The heating setpoint is 15 °C (factory setting), and the cooling setpoint is 30 °C.
Use P100 and P101 to adjust the Protection mode setpoints.
The heating setpoint is 8 °C (frost protection, factory setting) and OFF for cooling.
