8.10 Anti-freeze protection of the hot water coil
For the anti-freeze protection of the hot water coil, the water controller is sent to the regulating device by
a TGA1 PT1000 sensor attached to the coil output collector (See diagram "4.2 Connection of valves and
antifrost sensor", page 9). The regulating device generates a signal at all times for the valve motor
which allows a suffi cient hot water fl ow to be maintained in order to prevent frost in the coil.
If the water controller drops below the critical point (7°C), the fan is stopped and the damper (accessory)
is closed and an alarm is activated.
The anti-freeze protection continues to be active when the fan is off .
8.11 Entry for an external fi re signal
The adjustment is confi gured to receive a fi re contact. If the fi re entry is activated, the unit is stopped.
When the unit has been stopped by the fi re entry, it can only be restarted after the alarm has been dis-
charged. An automatic re-start can be confi gured. Two terminals are available for this entry (see wiring).
