9.5 Fan control
The HLS/HLD unit has single speed fan control only.
The clean fan filter reminder function counts the fan operating hours and displays message
“FIL” to remind the user to clean the fan filter as soon as the threshold is reached. This
does not impact the thermostat’s operation, which continues to run normally.
The clean filter reminder is reset when the operating mode is manually set to Protection
and back. See section 9.1
Clean Filter
Fan operation in
AutoTimer
In Auto Timer mode, the default fan mode is automatic. The fan mode can be changed to
manual by pushing the “FAN” button. The fan returns to the automatic default mode after
each switchover from Comfort to Energy Saving mode and vice versa.
When the electrical heater is switched off, the fan overruns for at least 3 minutes (param-
eter P54 factory set by VES) to avoid over temperature of the electrical heater or prevent the
thermal cutout from responding. In case of fan failure, the thermostat cannot protect the
electrical heater against over temperature. That is why the electrical heater features a
separate safety device (thermal cutout).
Note:
For the
BMS option the fan run on must be controlled by others
