controller configuration;
(defaults = hotel, relative, valve
protection enabled, NC, 0x40)
If the
Stop fan when heating /
cooling
function is activated, the
fan stops even if on manual
through register 24.
bit 0 ... presence mode
type (0
– hotel, 1 -
residential)
bit 1 … temperature
correction display
(0
–relative, 1 – absolute)
bit 2 ... stop fan when
heating
bit 3 ... stop fan when
cooling
bits 4-5 ... reserved
bit 6 ... valve exercising
(1
– enabled)
bit 7 ... valve type (0 ...
NC, 1 ... NO)

EEPROM
inputs configuration
DI1 ... presence
DI2 ... window / alarm contact
(default = inputs enabled, normally
open, i.e. active when contact on,
0x0F)
bit 0 … DI1 enabled for
operation mode control
bit 1 … DI2 enabled for
operation mode control
bit 2 ... DI1 sense
(0
– NC– normally closed,
1
–NO– normally open)
bit 3 ... DI2 sense
(0
– NC – normally closed,
1
– NO–normally open)

controller P-band
(input deviation
for output proportional part of
100 %)
or
hysteresis if On/Off
(hysteresis for heating is under the
setpoint, for cooling above the set-
point)

controller I
– constant; depends on
bandwidth if out of bounds, a new
recalculated value is set after
restart
in seconds; if set to 0,
integration part is
