EMERGENCY FUNCTIONING
The two following failure cases are fore-
seen when the thermostat operates in
the described manner.
NO WATER PROBE
- Ventilation is always active
- The season change is made on the
basis of the difference between the set-
ting made and the actual ambient tem-
perature. If the ambient temperature
exceeds by a value equal to the dead
band, the Heating setpoint switches to
the Cooling mode. If the ambient tem-
perature drops by a value equal to the
VENTILATION CYCLES OF 2-PIPE SYSTEM WITHOUT AMBIENT PROBE
AMBIENT PROBE ABSENT (4 PIPES)
In this case the thermostat operates as
follows:
- OFF - Aux Mode
The valves are closed
The fan is off
- AUTO, V1, V2, V3 mode:
The operating season is decided
according to the position of the tem-
perature selector and it is activated by
the respective valve as shown in the
Figure
The ventilation in this case is always
performed according to the ON-OFF
cycles, however, increasing the ON
phase from the central position. In
this way the maximum ventilation can
be required with the selector at the

it switches to the Heating mode.
- The turning on/off of the resistance
does not depend in this case on the
temperature of the water but on the
sheer demand for the thermostat opera-
tion
