Control function
The conguration of this option should be done through the master controller.
Conguration → Space heating → Cycle 2→Mixing valve
Mark Description Default Value Range Steps Units
RTV Rotation time 140 10-500s 10s s
PB Proportion Factor 6 0-20 0.2 %/°C
IRF Integral Factor 2.5 0-20 0.1 %/°C.min
Overheat protection oset 6 OFF, 3-10 1 °C
NOTE:
1. Mixing valve is eld-supplied and Conguration should be adjusted based on the selected Mixing valve and operation
conrmation.
2. [Overheat protection oset] is used in case of a mixing valve malfunction (i.e.: blocked). The protection has no eect in
case it is set to OFF. Overheat in Water Cycle 2 may cause alarm 73 if Overheat protection is set .
3. Mixing valve has 2 operation terminals of closing valve and opening valve. Optional output signal need be congured
as function of [Mixing valve Close] and [Mixing valve Open] and wire the Mixing valve based on the Conguration. Refer
to10.10.
4. ESBE ARA661 is recommended as Mixing valve and bypass pipe before Mixing valve should be tuned to balance water
circulation. Bypass pipe before Mixing valve can be skipped if equivalent Bypass replacement is tted.
Space heating is operated by Water Cycle 1 or combination of Water Cycle 1 and Water Cycle 2. And There are max. 4
room thermostats that can be incorporated to each Water Cycle (Cycle 1 and Cycle 2). It is possible to create Cycle 2
without Second water temperature control (no Mixing valve/WP2/Tow2) to just manage room thermostats and zone control.
NOTE:
1. Set [DSW5-3] as [ON ] to cancel sensor alarm of [Tow2].
2. Set water temperature for Cycle 1 equally to Cycle 2.
3. Set [Overheat protection oset] as [OFF]. Overheat in Water Cycle 2 may cause alarm 73 if Overheat protection is set.
