Input variables
The following values can be sent to the CORA-HKT (not changeable).
Room temp.
[°C]
The current room temperature can also come from an external sensor. Help
-
ful in case the HKT‘s own measured temperature is not reliable.
Set room temp.
[°C]
The target room temperature the HKT should aim for.
Heating
digital [On/Off]

= fully closed
100% = fully opened
If Heating and Cooling are
On

ously, the valve will be opened fully.
If both are
Off
simultaneously, the valve will
be closed fully.
Cooling

100% = fully closed
Set position
[0-100%]
The desired position of the valve can be set manually. Helpful in case several
HKTs in the same room regulate different radiators. See programming exam

cation
pulse
Every two weeks, the valve is opened fully, flushed with water for roughly 5
seconds, closed fully and then returned to set position. This serves to decal
-
cify the valve.
Through a pulse, the decalcification process can be started manually to pre
-
vent automatic decalcification at an undesired time. The manual start of the
process resets the timer for the automatic process.
The „fully opened“ position is defined by the initialisation run (see page 3), „Fully opened“
