3.3 Room temperature setpoints
3.3.1 Description
The factory setting for the Comfort basic setpoint is 21 °C and can be changed in
the thermostat’s EEPROM via parameter P08 or via bus with communication object
" Comfort basic setpoint". The last intervention always wins.
The Comfort setpoint can be adjusted via the +/- buttons,
or via bus from a remote device like a touchpanel, operating unit, etc.
The last intervention always wins.
If the “Temporary setpoint” function is enabled via parameter P69, the Comfort
setpoint adjusted via the +/- buttons or via bus is set back to the Comfort basic
setpoint stored in P08 when the operating mode changes.
For comfort or energy saving purposes, the setpoint setting range can be limited to
minimum (P09) and maximum (P10).
If the minimum limit P09 is set lower than the maximum limit P10, both heating
and cooling are adjustable between these 2 limits
The customer 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 (P33). The unit stops to energize the heating / cooling outputs as
soon as the room temperature reaches the dead zone.
Example
5°C 40°C25°C18°C
P10P09
Cooling setpoint adjustable 18…25 °C
Heating setpoint adjustable 18…25 °C
If the minimum limit P09 is set higher than the limit P10, then
– The setting range of cooling setpoint is from P09…40 °C in place of 5…40 °C
– The setting range of 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 to save energy costs.
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 (P09 or
P10) of the inactive sequence. E.g. the thermostat is in 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.
Example
5°C 40°C25°C21°C
P09P10
Cooling setpoint adjustable 25…40 °C
Heating setpoint adjustable 5…21 °C
For heating and cooling applications (e.g. 4-pipe):
P09 is the setpoint for cooling and P10 the setpoint for heating
– The setpoint can not be adjusted via the rotary knob
