pump is put into operation. A heating coil that has been installed is protected from icing by an
anti-freeze thermostat. If the supply air temperature drops below the temperature set on the
anti-freeze controller, the valves close and the circulating pump runs constantly, the heating valve
opens and a fault message is given. The device automatically runs „PRE-RINSING“ until heating
provides the desired operation temperature. The unit restarts then automatically. If the desired
operating temperature can not be achieved after 20 min., an error message is displayed. After-
wards, the unit turns itself completely off until the fault is repaired. (see 13.2. Error table F07)

valve is opened and at the same time the cooling unit enable output is activated.
The minimum switching time for ON and OFF is 5 minutes each, i.e. the cooling unit is switched on
and off a maximum of six times per hour.
