The controller is equipped with a multicolour LED in the centre of the Lightwheel
indicating the following states:

Systems
System 1 (fl ow temperature controlled heating with optional effi ciency
control of the heat exchange – fl ow controlled cooling)
R2 = open
R3 = closed
The controller monitors the room thermostat (TA).

If the room thermostat demands heat, the pump (R1) starts and R4 is energised for
the heating demand. The temperature at S2 is monitored. The mixer is controlled so
,
®
that the adjusted temperature Tset is reached and maintained at S2.
If the TFcalculated option (return temperature monitoring S3, factory setting =
active) is activated, the controller runs a heat demand-based calculation of the set
fl ow temperature needed for keeping the system at the optimum temperature. For
this purpose, the return temperature (S3) is monitored. The calculated set fl ow
temperature is displayed as TFset..
The controller is equipped with a non-adjustable safety shutdown function. If the
temperature at S2 reaches or exceeds 90 °C, the mixer closes. The warning symbol
⚠ appears on the screen and the Lightwheel
at S2 reaches or exceeds 95 °C,R1 and R4 switch off. The Lightwheel
If the TMax option is activated, the value for the safety shutown function can be
reduced. If the temperature at S2 exceeds TMax by less than 5 K, the warning sym-
bol ⚠ appears on the screen and the Lightwheel
at S2 exceeds TMax by more than 5 K, R1 and R4 switch off. The Lightwheel
fl ashes red.
If the Cooling option is activated, the mixer is controlled so that the adjusted
cooling temperature TCool is reached and maintained at S2. The S7 contact can be
used for connecting a switch for remotely controlling the heating / cooling mode.
Contact open = cooling mode
Contact closed = heating mode
If the Condensation option is activated, the controller monitors a dew point
switch. If the dew point switch triggers an alarm, cooling stops and the warning
symbol is indicated. If the humidity falls again below the adjusted value, the cooling
mode continues.
