HERMAL
The "thermal" function activates an automatic heat dissipation
algorithm. This logic is available only in Winter operating mode
and is activated only when there is no system low temperature
request.
You can set the following parameters:
Enable: Yes/No Enable/Disable function.
Tmp: Function activation system delivery temperature.
Hyst: Operating hysteresis.
Tstart:Pump operation time.
Tstop:Delay between dissipation cycles.
Cycles: Number of dissipation cycles before the alarm locks
the function.
Below are listed the default values and the pump activation
scheme according to the delivery temperature.

THERMAL OPERATING LOGIC:
The starting condition is that the system must be on standby
(no production request, recirculating mixing valves, pump off).
If, for any reason, the delivery temperature rises above 45+2°C,
then the thermal function will be activated. This will simply
activate the system pump (15 sec) and the zone output. If this
operation does not bring the temperature back to 45-2°C, the
function will be reactivated after a 90 sec delay for the number
of dissipation cycles (5 cycles). At the end of all the cycles, if the
temperature has not decreased, the thermal alarm will set off.
