8.2.3 Heating threshold values
Stage 1
Release of fan actuation up to 20% when the configured temperature
is exceeded.
Stage 2
Release of fan actuation up to 60% when the configured temperature
is exceeded.
Stage 3
Release of fan actuation up to 100% when the configured temperature
is exceeded.
8.2.4 Cooling threshold values
Stage 1
Release of fan actuation up to 20% when the configured temperature
is transgressed.
Stage 2
Release of fan actuation up to 60% when the configured temperature
is transgressed.
Stage 3
Release of fan actuation up to 100% when the configured temperature
is transgressed.
8.3 Controller
It provides the option of adapting general temperature control parameters and
specific control functions for heating and cooling mode. The following
parameters can be altered in the "Controller" "General” menu:
Hysteresis:
Switching-on and off hysteresis for the heating and cooling valve.
(refer to chapter 5.3 for the effect)
Start-up mode:
This parameter specifies the controller mode after a restart of the unit.
Neutr. zone 4-p
In 4-pipe mode, the heating and cooling setpoint is calculated
depending on the neutral zone.
Heating setpoint = setpoint
– (Neutr. zone 4-p / 2)
Cooling setpoint = se (Neutr. zone 4-p / 2)
Standby
If the unit is in standby mode, the setpoint for heating mode is reduced
by the set parameter. In cooling mode, the setpoint is increased
accordingly.
ECO setback
In ECO mode, the setpoint for heating mode is lowered by the
parametrised value.
ECO boost
In ECO mode, the setpoint for cooling mode is raised by the
parametrised value.
Presence/Eco
This parameter is used to define the interaction between the presence
function and ECO mode:
Hold: ECO mode is enabled/disabled independently of the occupied
status.
