If the minimum limit
P09 is set higher
than the limit P10, …
– the setting range of the cooling setpoint is from
P09…40 °C
in place of
5…40 °C,
– the setting range of the heating setpoint is from
5…P10 °C
in place of
5…40 °C.
This allows the user to limit the maximum heating setpoint and the minimum
cooling setpoint. This concept helps save energy costs.
∂
For
heating OR cooling applications
:
– The thermostat operates with the setpoint of the active sequence:
In heating mode, the heating setpoint is active and adjustable via the rotary
knob. In cooling mode, the cooling setpoint is active and adjustable via the
rotary knob
– Switching from the heating to the cooling setpoint and vice versa occurs
when the room temperature reaches the adjusted limitation (P09 or P10) of
the
inactive
sequence (e.g. the thermostat is in the heating sequence and
runs with the heating setpoint). When the room temperature reaches P09,
the thermostat switches to cooling mode and runs with the cooling setpoint
as long as the room temperature does not drop below P10

Cooling setpoint adjustable: 25…40 °C

Use P11 and P12 to adjust the Economy mode setpoints.
The heating setpoint is factory-set to
15 °C
, and the cooling setpoint to
30 °C
.
Use P65 and P66 to adjust the Protection mode setpoints.
The heating setpoint is factory-set to
8 °C
(frost protection) and to
OFF
for cooling.
If a setpoint (Economy or Protection) is set to OFF, the thermostat does not control
the room temperature in the corresponding mode (heating or cooling).
This means no protective heating or cooling function and thus risk of frost in
heating mode or risk of overtemperature in cooling mode!
The Economy setpoints are accessible at the Service level (P11, P12), the
Protection setpoints at the Expert level (P65, P66).
