5.22.2. Temperature difference to switch on and off the return flow increase
(Δt on / Δt off)
A temperature difference between the storage sensor (5.22.4.) and the heating return flow
sensor (5.22.3.) to switch on (Δt on) and off (Δt off) the return flow increase function.
5.22.3. Return flow sensor
Teplotní čidlo umístěné na topné zpátečce – je očekávána nižší teplota než na čidle zásobníku.
5.22.4. Storage sensor
Temperature sensor for a storage tank (e.g. a thermal store) – a higher temperature is
expected than at the heating return flow sensor.
5.23. Circulation (DHW recirculation)
The menu is available only if the DHW circulation function is assigned to an output in
menu 7. Special functions.
Switching on the DHW recirculation pump when the temperature in the recirculation piping
drops below the min. value.
5.23.1. Min. DHW recirculation temperature (Tmin)
The min. DHW recirculation temperature to switch on the circulation pump. The circulation
pump will switch on when the temperature at the reference sensor (5.23.3.) drops below this
value.
5.23.2. Hysteresis for switching off the pump
Hysteresis for switching off the circulation pump. If the temperature at the reference sensor
reaches the set value (5.23.1. Tmin) + hysteresis, the DHW circulation pump will be shut
down.
5.23.3. Circulation sensor
Temperature sensor in the DHW recirculation piping.
5.23.4. Circulation pause time
Pause time before the circulation pump is started again after it was shut down, when also the
requirement
Tmin + Hysteresis
is met. Intended to prevent frequent starting of the circulation
pump.
5.23.6. Circulation periods
Time program of the DHW circulation pump. For each weekday, three time intervals can be
specified when the DHW circulation pump function is enabled. The function will be switched
on in these intervals only if the switch-on condition for DHW recirculation is met.
5.24. Room dehumidifier (Dehumidifier)
The menu is available only if the Dehumidifier function is assigned to an
output in menu 7. Special functions. A special room unit Caleon needs to be
connected to the controller.
Switching on dehumidifying operation in the selected operating mode when the max. humidity
set here is exceeded.
5.24.1. Operating mode
The operating mode of the dehumidifier function can be set here.
Summer
= Dehumidifier is active only in the HC summer mode (see 5.1.2. and 5.1.3.).
Circ.
= Dehumidifier is active only in the summer mode or if the HC circulation
pump is running in winter mode.
Year round
= Dehumidifier is active all year round disregarded of the heating circuit mode.
