Note!
Software versions 3.3, 3.4 and 3.5 of the operator terminal offer more functions than
the number of functions available. The only functions that can be selected are None
and Limit thermostat HC. With software version 3.6 and higher, these are the only 2
selectable functions.

Limit thermostat HC
If the extension module is used for the heating circuit, an external limit thermostat (e.g.
for floor heating) can be connected to input EX21 (AC 230 V).
If the limit thermostat cuts out, ...
-
the mixing valve is closed and the pump deactivated,
-
an error message Limit thermostat HCx is delivered,
-
status Limit thermostat cut out is generated.
If the function of the extension module is set to Heating circuits 1...3 or Heating
circuit/cooling circuit 1, and the function of input EX21 for the same module to Limit
thermostat HC, the module gives consideration to the state at input EX21 in that case,
for control of the relay outputs (pump and mixing valve opening/closing).
